Before the Court are two appeals challenging gun-control legislation enacted by the New York and Connecticut legislatures in the wake of the 2012 mass murders at Sandy Hook Elementary School in New-town, Connecticut. The New York and Connecticut laws at issue prohibit the possession of certain semiautomatic “assault weapons” and large-capacity magazines. Following the entry of summary judgment in favor of defendants on the central claims in both the Western District of New York (William M. Skretny, Chief Judge) and the District of Connecticut (Alfred V. Covello, Judge), plaintiffs in both suits now press two arguments on appeal. First, they challenge the constitutionality of the statutes under the Second Amendment; and second, they challenge certain provisions of the statutes as unconstitutionally vague. Defendants in the New York action also cross-appeal the District Court’s invalidation of New York’s separate seven-round load limit and voiding of two statutory provisions as facially unconstitutionally vague.
We hold that the core provisions of the New York and Connecticut laws prohibiting possession of semiautomatic assault weapons and large-capacity magazines do not violate the Second Amendment, and that the challenged individual provisions are not void for vagueness. The particular provision of New York’s law regulating load limits, however, does not survive the requisite scrutiny. One further specific provision — Connecticut’s prohibition on the non-semiautomatic Remington 7615 — unconstitutionally infringes upon the Second Amendment right. Accordingly, we AF
BACKGROUND
I. Prior “Assault Weapon” Legislation
New York and Connecticut have long restricted possession of certain automatic and semiautomatic firearms that came to be known as “assault weapons.” In 1993, Connecticut’s General Assembly adopted the state’s first assault-weapon ban, which criminalized the possession of firearms “capable of fully automatic, semiautomatic or burst fire at the option of the user,” including 67 specifically enumerated semiautomatic firearms.
The following year, after five years of hearings on the harms thought to be caused by certain firearms, the U.S. Congress enacted legislation restricting the manufacture, transfer, and possession of certain “semiautomatic assault weapons.”
Following the passage of the federal assault-weapons ban, both New York, in 2000, and Connecticut, in 2001, enacted legislation that closely mirrored the federal statute, including the two-feature test for prohibited semiautomatic firearms.
On December 14, 2012, a gunman shot his way into Sandy Hook Elementary School in Newtown, Connecticut and murdered twenty first-graders and six adults using a semiautomatic AR-15-type- rifle with ten large-capacity magazines. This appalling attack, in addition to other recent mass shootings, provided the immediate impetus for the legislation at issue in this appeal.
New York enacted the Secure Ammunition and Firearms Enforcement Act (SAFE Act) on January 15, 2013.
The SAFE Act also bans magazines that can hold more than ten rounds of ammunition or that can be readily restored or converted to accept more than ten rounds.
The SAFE Act’s large-capaeity-maga-zine ban contains an additional, unique prohibition on possession of a magazine loaded with more than seven, rounds of ammunition.
III. The Connecticut Legislation
Several months after New York passed the SAFE Act, and after extensive public hearings and legislative and executive study, Connecticut adopted “An Act Concerning Gun Violence Prevention and Children’s Safety” on April 4, 2013, and later amended the 8 on June 18, 2013.
The June 2013 amendment to the Connecticut legislation criminalizes the possession of “[l]arge capacity magazine[s]” that can hold, or can be “readily restored or converted to accept,” more than ten rounds of ammunition.
IV. Procedural History
Plaintiffs — a combination of advocacy groups, businesses, and individual gun owners — filed suit against the governors of New York and Connecticut and other state officials, first in the Western District of New York on March 21, 2013 and then in the District of Connecticut on May 22, 2013. In both actions, plaintiffs sought declaratory and injunctive relief for alleged infringement of their constitutional rights. Specifically, plaintiffs contended that the statutes’ prohibitions on semiautomatic assault weapons and large-capacity magazines violate their Second Amendment rights, and that numerous specific provisions of each statute are unconstitutionally vague. In the New York action, plaintiffs also challenged the seven-round load limit as a violation of the Second Amendment.
Following plaintiffs’ motions for preliminary injunctions, parties in both suits cross-moved for summary judgment. On December 31, 2013, Chief Judge Skretny of the Western District of New York granted in part and denied in part the cross-motions for summary judgment.
On January 30, 2014, Judge Covello of the District of Connecticut granted defendants’ motion for summary judgment in its entirety.
Plaintiffs thereafter appealed. In the New York action only, defendants cross-appeal the District Court’s judgment insofar as. it invalidated the SAFE Act’s seven-round load limit ánd voided as unconstitutionally vague the SAFE Act’s prohibitions on the misspelled “muzzle break”
DISCUSSION
These appeals present two questions: first, whether the Second Amendment permits the regulation of the assault weapons and large-capacity magazines at issue here; and second, whether the challenged provisions of the statutes provide constitutionally sufficient notice of the conduct proscribed.
We review de novo a district court’s order granting summary judgment, construing the evidence in the light most favorable to the non-moving party.
V. Second Amendment Challenge
We conclude that the core challenged prohibitions of assault weapons and large-capacity magazines do not violate the Second Amendment. Guided by the teachings of the Supreme Court, our own jurisprudence, and the examples provided by our
a. Heller and McDonald
The Second Amendment provides that “[a] well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.”
Having established these basic precepts, Heller concluded that the District of Columbia’s ban on possession of handguns was unconstitutional under the Second Amendment
Heller stopped well short of extending its rationale to other firearms restrictions. Indeed, Heller explicitly identified as “presumptively lawful” such “regulatory measures” as “prohibitions on the possession of firearms by felons and the mentally ill, ... laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, [and] laws imposing conditions and qualifications on the commercial sale of arms.”
Aside from these broad guidelines, Heller offered little guidance for resolving future Second Amendment challenges. The Court did imply that such challenges are subject to one of “the standards of scrutiny that we have applied to enumerated constitutional rights,” though it declined to say which,
b. Analytical Rubric
Lacking more detailed guidance from the Supreme Court, this Circuit has begun to develop a framework for determining the constitutionality of firearm restrictions.
First, we consider whether the restriction burdens conduct protected by the Second Amendment.
This two-step rubric flows from the dictates of Heller and McDonald and our own precedents in Kachalsky and Decastro.
c. First Step: Whether the Second Amendment Applies
As an initial m'atter, then, we must determine whether the challenged legislation impinges upon conduct protected by the Second Amendment. The Second Amendment protects only “the sorts of
i. Common Use
The parties contest whether the assault weapons at issue here are commonly owned. Plaintiffs argue that the weapons at issue are owned in large numbers by law-abiding Americans. They present statistics showing that nearly four million units of a single assault weapon, the popular AR-15, have been manufactured between 1986 and March 2013.
This much is clear: Americans own millions of the firearms that the challenged legislation prohibits.
The same is true of large-capacity magazines, as defined by the New York and Connecticut statutes. Though fewer statistics are available for magazines, those statistics suggest that about 25 million large-capacity magazines were available in 1995, shortly after the federal assault weapons ban was enacted, and nearly 50 million such magazines—or nearly two large-capacity magazines for each gun capable of accepting one—were approved for import by 2000.
Even accepting the most conservative estimates cited by the parties and by ami-ci, the assault weapons and large-capacity magazines at issue are “in common use” as that term was used in Heller. The D.C. Circuit reached the same conclusion in its well-reasoned decision in Heller II, which upheld the constitutionality of a District of Columbia gun-control act substantially similar to those at issue here.
To be sure, as defendants note, these assault weapons and large-capacity magazines are not as commonly owned as the handguns at issue in Heller, which were “the most popular weapon chosen by Americans for self-defense in the home.”
ii. Typical Possession
We must next determine whether assault weapons and large-capacity magazines are “typically possessed by law-abiding citizens for lawful purposes.”
The parties offer competing evidence about these weapons’ “typical use.” Plaintiffs suggest that assault weapons are among the safest and most effective firearms for civilian self-defense.
Even if defendants are correct,
Looking solely at a weapon’s association with crime, then, is insufficient. We must also consider more broadly whether the weapon is “dangerous and unusual” in the hands of law-abiding civilians. Heller expressly highlighted “weapons that are most useful in military service,” such as the fully automatic M-16 rifle, as weapons that could be banned without implicating the Second Amendment.
Ultimately, then, neither the Supreme Court’s categories nor the evidence in the record cleanly resolves the question of whether semiautomatic assault weapons and large-capacity magazines are “typically possessed by law-abiding citizens for
In the absence of clearer guidance from the Supreme Court or stronger evidence in the record, we follow the approach taken by the District Courts and by the D.C. Circuit in Heller II and assume for the sake of argument that these “commonly used” weapons and magazines are also “typically possessed by law-abiding citizens for lawful purposes.”
d. Second Step: Level of Scrutiny
Having concluded that the statutes impinge upon Second Amendment rights, we must next determine and apply the appropriate level of scrutiny.
Though Heller did not specify the precise level of scrutiny applicable to firearms regulations, it rejected mere rational basis review as insufficient for the type of regulation challenged there.
i. The Core of the Right
By their terms, the statutes at issue implicate the core of the Second Amendment’s protections by extending into the home, “where the need for defense of self, family and property is most acute.”
ii. The Severity of the Burden
In Decastro, we explained that heightened scrutiny need not apply to “any mar
The practice of applying heightened scrutiny only to laws that “burden the Second Amendment right substantially” is, as we noted in Decastro, broadly consistent with our approach to other fundamental constitutional rights, including those protected by the First and Fourteenth Amendments.
The scope of the legislative restriction and the availability of alternatives factor into our analysis of the “degree to which the challenged law burdens the right.”
The laws at issue are both broad and burdensome. Unlike statutes that “merely regulate the manner in which persons may exercise their Second Amendment rights,” these laws impose an outright ban statewide.
Heightened scrutiny need not, however, “be akin to strict scrutiny when a law burdens the Second Amendment” — particularly when that burden does not constrain the Amendment’s “core” area of protection.
Accordingly, we conclude that intermediate, rather than strict, scrutiny is appropriate. This conclusion coheres not only with that reached by the D.C. Circuit when considering substantially similar gun-control laws, but also with the analyses undertaken by other courts, many of which have applied intermediate scrutiny to laws im
e. Application of Intermediate Scrutiny
Though “intermediate scrutiny” may have different connotations in different contexts,
i. Prohibition on “Assault Weapons”
To survive intermediate scrutiny, the “fit between the challenged regulation [and the government interest] need only be substantial, not perfect.”
In making this determination, we afford “substantial deference to the predictive judgments of the legislature.”
Both states have done so with respect to their prohibitions on certain semiautomatic firearms.
The record reveals that defendants have tailored the legislation at issue to address these particularly hazardous weapons. The dangers posed by some of the military-style features prohibited by the statutes — such as grenade launchers and silencers — are manifest and incontrovertible.
The legislation is also specifically targeted to prevent mass shootings like that in Newtown, in which the shooter used a semiautomatic assault weapon. Plaintiffs complain that mass shootings are “particularly rare events” and thus, even if successful, the legislation will have a “minimal
Defendants also have adduced evidence that the regulations will achieve their intended end of reducing circulation of assault weapons among criminals.
Ultimately, “[i]t is the legislature’s job, not ours, to weigh conflicting evidence and make policy judgments.”
ii. Prohibition on Large-Capacity Magazines
The same logic applies a fortiori to the restrictions on large-capacity magazines.
We therefore conclude that New York and Connecticut have adequately established a substantial relationship between the prohibition of both semiautomatic assault weapons and large-capacity magazines and the important — indeed, compelling — state interest in controlling crime. These prohibitions survive intermediate scrutiny.
iii. Seven-Round Load Limit
Though the key provisions of both statutes pass constitutional muster on this record, another aspect of New York’s SAFE Act does not: the seven-round load limit, which makes it “unlawful for a person to knowingly possess an ammunition feeding device where such device contains more than seven .rounds of ammunition.”
As noted above, the seven-round load limit was a second-best solution. New York determined that only magazines containing seven rounds or fewer can be safely possessed, but it also recognized that seven-round magazines are difficult to obtain commercially. Its compromise was to permit gun owners to use ten-round magazines if they were loaded with seven or fewer rounds.
On the record before us, we cannot conclude that New York has presented sufficient evidence that a seven-round load limit would best protect public safety. Here we are considering not a capacity restriction, but rather a load limit. Nothing in the SAFE Act will outlaw or reduce the number of ten-round magazines in circulation. It will not decrease their availability or in any way frustrate the access of those who intend to use ten-round magazines for mass shootings or other crimes. It is thus entirely untethered from the stated rationale of reducing the number of assault weapons and large capacity magazines in circulation.
To be sure, the mere possibility of criminal disregard of the laws does not foreclose an attempt by the state to enact firearm regulations. But on intermediate scrutiny review, the state cannot “get away with shoddy data or reasoning.”
We turn now to plaintiffs’ second challenge to the New York and Connecticut laws — their claim that provisions of both statutes are unconstitutionally vague. The New York defendants cross-appeal Chief Judge Skretny’s ruling that two provisions of the SAFE Act are void because of vagueness.
a. Legal Standards
Grounded in due process principles, the void-for-vagueness doctrine provides that “[n]o one may be required at peril of life, liberty or property to speculate as to the meaning of penal statutes.”
Because plaintiffs pursue this “pre-enforcement” appeal before they have been charged with any violation of law, it constitutes a “facial,” rather than “as-applied,” challenge.
Seeking to avoid this prohibitively high bar, plaintiffs urge us to follow the different approach that a plurality of the Supreme Court took in City of Chicago v. Morales.
b. Application
i. “Can be readily restored or converted to accept”
Both the New York and Connecticut statutes criminalize the possession of magazines that “can be readily restored or converted to accept” more than ten rounds of ammunition.
This statutory language dates at least to the 1994 federal assault-weapons ban and later appeared in New York’s 2000 law. As Chief Judge Skretny noted, there is no record evidence that it has given rise to confusion at any time in the past two decades.
Plaintiffs’ purported concern — that this provision might be unfairly used to prosecute an ordinary citizen for owning a magazine that only a gunsmith equipped with technical knowledge and specialized tools could “readily convert”
In sum, we affirm the judgments of both District Courts finding that this phrase is not unconstitutionally vague.
ii. Capacity of Tubular Magazines
The New York plaintiffs contend the SAFE Act’s ten-round magazine restriction
iii. “Copies or Duplicates”
Plaintiffs challenge the Connecticut statute’s definition of assault weapon to include certain specified firearms and any “copies or duplicates thereof with the capability of’ the listed models.
We review the statutory language within its context, relying if necessary on the canons of statutory construction and legislative history.
In this manner, the Connecticut legislation avoids the deficiency of an assault-weapons ban struck down by a sister Circuit as unconstitutionally vague in Springfield Armory, Inc. v. City of Columbus.
We therefore agree with Judge Covello that the “copies or duplicate” provision of the Connecticut statute at issue here is sufficiently definite to survive a void-for-vagueness challenge.
iv. “Version”
We apply similar logic to our analysis of New York’s prohibition of semiautomatic pistols that are “semiautomatic version[s] of an automatic rifle, shotgun or firearm.”
We disagree. The SAFE Act’s terminology has been used in multiple state and federal firearms statutes, including the 1994 federal assault-weapons ban, as well as in government reports, judicial decisions, and published books.
v. “Muzzle Break”
Finally, Chief Judge Skretny also struck down as impermissibly vague a provision of New York’s SAFE Act that listed among prohibited military-style features such muzzle attachments as “a flash suppressor, muzzle break, muzzle compensator, or threaded barrel designed to accommodate a flash suppressor, muzzle break,, or muzzle compensator.”
This is, in our view, an overstatement. Because the misspelled homophone “muzzle break” has no accepted meaning, there is no meaningful risk that a party might confuse the legislature’s intent. Further, its placement within a list of muzzle attachments makes the misspelled term’s meaning even clearer. What is more, because the adjacent statutory term “muzzle compensator” is synonymous with muzzle brake, and thus independently covers,the prohibited conduct, this issue is of little moment. Nonetheless, vagueness doctrine requires only that the statute provide “sufficiently definite warning as to the proscribed conduct when measured by common understanding and practices.”
CONCLUSION
To summarize, we hold as follows:
(1) The core prohibitions by New York and Connecticut of assault weapons and large-capacity magazines do not violate the Second Amendment.
(a) We assume that the majority of the prohibited' conduct falls within the scope of Second Amendment protections. The statutes are appropriately evaluated under the constitutional standard of “intermediate scrutiny” — that is, whether they are “substantially related to the achievement of an important governmental interest.”
(b) Because the prohibitions are substantially related to the important governmental interests of public safety and crime reduction, they pass constitutional muster.
We therefore AFFIRM the relevant portions of the judgments of the Western District of New York and the District of Connecticut insofar as they upheld the constitutionality of state prohibitions on semiautomatic assault weapons and large-capacity magazines.
(2) We hold that the specific prohibition on the non-semiautomatic Remington 7615 falls within the scope of Second Amendment protection and subsequently fails intermediate scrutiny. Accordingly, we REVERSE that limited portion of the judgment of the District of Connecticut. In doing so, we emphasize the limited nature of our holding with respect to the Remington 7615, in that it merely reflects the presumption required by the Supreme Court in 'District of Columbia v. Heller that the Second Amendment extends to all bearable arms, and that the State, by failing to present any argument at all regarding this weapon or others like it, has failed to rebut that presumption. We do not foreclose the possibility that States could in the future present evidence to support such a prohibition.
(3) New York’s seven-round load limit does not survive intermediate scrutiny in the absence of requisite record evidence and a substantial relationship between the statutory provision and important state safety interests. We therefore AFFIRM the judgment of the Western District of New York insofar as it held this provision unconstitutional. ,
(4) No challenged provision in either statute is unconstitutionally vague. Accordingly, we AFFIRM the judgments of the District of Connecticut and the Western District of New York insofar as they denied vagueness challenges to provisions involving the capacity of tubular magazines, “copies' or duplicates,” or a firearm’s ability to “be readily restored or converted.” We REVERSE the judgment of the Western District of New York insofar as it found language pertaining to “versions” and “muzzle breaks” to be unconstitutionally vague.

. Though we assume without deciding that the bulk of the challenged legislation is entitled to Second Amendment protection, we decide as much with respect to Connecticut's prohibition of the Remington Tactical 7615, a non-semiautomatic pump-action rifle. See Defendants' Br., No. 14-319-cv, at 58.
Heller emphasizes that the “the Second Amendment extends, prima facie, to all instruments that constitute bearable arms.” Heller, 554 U.S. at 582, 128 S.Ct. 2783. In other words, it identifies a presumption in favor of Second Amendment protection, which the State bears the initial burden of rebutting. See Ezell, 651 F.3d at 702-03 ("[I]f the government can establish that a challenged firearms law regulates activity falling outside the scope of the Second Amendment ... then the analysis can stop there....” (emphasis supplied)); cf. Virginia v. Black, 538 U.S. 343, 369, 123 S.Ct. 1536, 155 L.Ed.2d 535 (2003) (Scalia, J., concurring in part, concurring in the judgment in part, and dissenting in part) (defining "prima facie evidence” as that which, “if unexplained or un-contradicted, is sufficient to sustain a judgment in favor of the issue which it supports” (quoting Black's Law Dictionary 1190 (6th ed.1990))). Because the State, focused on semiautomatic weapons, see post note 112, has failed to make any argument that this pump-action rifle is dangerous, unusual, or otherwise not within the ambit of Second Amendment protection, the presumption that the Amendment applies remains unrebutted.
To be sure, Heller also noted that certain “presumptively lawful regulatory measures” ostensibly fall outside of the Second Amendment’s prima facie protections. Id. at 627 n. 26, 128 S.Ct. 2783. Nonetheless, like the D.C. Circuit in Heller II, we conclude that these particular restrictions are not entitled to "a presumption of validity.” Heller II, 670 F.3d at 1260 (emphasis supplied).
We emphasize that our holding with respect to the Remington 7615 — at both steps of our analysis — reflects the State's failure to present any argument at all regarding this weapon or others like it. We do not foreclose the possibility that states could in the future present evidence to support such a prohibition.
.Plaintiffs’ effort to avoid' the two-step framework laid out here is unavailing. They argue that the application of means-ends scrutiny in this case would be an "exercise in futility.” Plaintiff’s Br., No. 14-36-cv, at 13 (quoting Kachalsky, 701 F.3d at 89 n.- 9); Plaintiff's Br., No. 14-319-cv, at 12 (same). We reject that argument. As plaintiffs themselves concede, this Court made very clear in Kachalsky that "Heller's reluctance to announce a standard of review” should not be interpreted as a “signal that courts must look solely to the text, history, and tradition of the
. 304 U.S. 144, 152 n. 4, 58 S.Ct. 778, 82 L.Ed. 1234 (1938); see Heller, 554 U.S. at 628 n. 27, 128 S.Ct. 2783.
. 554 U.S. at 628 n. 27, 128 S.Ct. 2783. At the same time, Heller’s approval of certain "presumptively lawful regulatory measures,” id. at 627 n. 26, 128 S.Ct. 2783, has been construed by some to rule out strict scrutiny as well. Indeed, Justice Breyer’s dissent states, without opposition from the Court's opinion, that "the majority implicitly, and appropriately, rejected] th[e] suggestion [to apply strict scrutiny to gun regulations] by broadly approving a set of laws ... whose constitutionality under a strict scrutiny standard would be far from clear.” Id. at 688, 128 S.Ct. 2783 (Breyer, J., dissenting). Chief Judge Skretny cited this interpretation with approbation. NYSRPA, 990 F.Supp.2d at 366. Upon closer' inspection, however, we think it likely that the Heller majority identified these "presumptively lawful” measures in an attempt to clarify the scope of the Second ' Amendment’s reach in the first place—the first step of our framework—but not to intimate a view as to whether strict scrutiny applies in the second step.
. See Ezell, 651 F.3d at 703.
. Heller, 554 U.S. at 628, 128 S.Ct. 2783. This conclusion is predicated on our earlier assumption that the commonly used firearms at issue are also typically used for self-defense or other lawful purposes, and thus the prohibitions implicate the Second Amendment right. See ante V.c.ii.

Kwong v. Bloomberg, 723 F.3d 160, 167 (2d Cir.2013). The regulation in Kwong involved neither the outright prohibition of weapons in common use nor any direct limitation on the exercise of Second Amendment rights within the home.

Plaintiffs’ related argument — that the availability of unbanned firearms "is irrelevant under Heller," see Plaintiffs’ Br., No. 14-36-cv, at 32 — rests on a misapprehension of the Supreme Court's logic. To be sure, Heller did indicate that "[i]t is no answer to say ... that it is permissible to ban the possession of handguns so long as the possession of other firearms ij..e., long guns) is allowed.” 554 U.S. at 629, 128 S.Ct. 2783. But Heller went on to explain that handguns are protected as "the most popular weapon chosen by Americans for self-defense in the home.” Id. Of course, the same cannot be said of the weapons at issue here. Heller explicitly endorsed prohibitions against any "weapons not typically possessed by law-abiding citizens for lawful purposes,” including, for example, short-barreled shotguns. Id. at 625, 128 S.Ct. 2783. Our consideration of available alternatives' for self-defense thus squares with Heller’s focus on protecting that "core lawful purpose” of the Second Amendment right. Id. at 630, 128 S.Ct. 2783.
