OPINION OF THE COURT
The Government appeals from the order of the District Court dismissing the indictment against Melissa Huet (“Huet”) with prejudice. Huet was charged with aiding and abetting possession of a firearm by a convicted felon, in violation of 18 U.S.C. § 922(g)(1) and § 2. The District Court dismissed the indictment on the basis that: (1) it failed to state an offense for aiding and abetting under § 922(g)(1) and § 2; and (2) even if it did state an offense, the charge violated Huet’s rights under the Second Amendment of the U.S. Constitution. For the reasons set forth below, we will reverse and remand.
I.
On June 5, 2008, a federal grand jury sitting in the Western District of Pennsylvania returned a three-count indictment against Huet and her paramour, Marvin Hall (“Hall”). Counts One and Two, respectively, charged Hall with possession of a firearm by a convicted felon, in violation of 18 U.S.C. § 922(g)(1), and transfer of unregistered firearms, in violation of 26 U.S.C. § 5861(e). Count Three (“Count Three” or “the Indictment”) charged Huet with knowingly aiding and abetting the possession of a firearm by a convicted felon, in violation of 18 U.S.C. § 922(g)(1) 1 and § 2(a) 2 . On January 29, 2010, Hall pled guilty to Count One, and was sentenced to time served. On November 22, 2010, the District Court issued an order dismissing Count Three with prejudice. The Government filed a timely notice of appeal.
The allegations in the Indictment stem from an undercover FBI investigation into the activities of Morgan Jones (“Jones”) in Clarion County, Pennsylvania. The investigation focused on attempts to purchase illegal firearms and explosive devices for criminal activities, as well as the potential manufacturing and detonation of explosive devices. During their probe, FBI agents met Hall and Huet, who lived together. Over the next nine months, agents gathered evidence allegedly connecting Hall and Huet to various criminal activities, and on June 6, 2008, a valid search warrant (the “search warrant”) was executed on the couple’s Clarion County home. Agents *593 seized an SKS, Interordinance M59/66 rifle (“SKS rifle”) from an upstairs bedroom.
Although Huet is legally permitted to possess a firearm, Hall was convicted in 1999 of possessing an unregistered firearm, in violation of 26 U.S.C. § 5861(d), and is therefore prohibited from owning or possessing a firearm. After being informed of the raid, Huet allegedly told investigators that the guns in the house belonged to her and that it was not illegal for her to purchase weapons. Despite Huet’s assertions that she alone possessed the SKS rifle, the Government sought and obtained an indictment charging Hall with illegal possession of the weapon, and Huet with aiding and abetting Hall’s possession.
Huet moved to dismiss Count Three pursuant to Rule 12(b)(3)(B) of the Federal Rules of Criminal Procedure 3 on the basis that the Indictment failed to state an offense under § 922(g)(1) and §-2. Count Three states:
From on or about August 10, 2007, to on or about January 11, 2008, in the Western District of Pennsylvania, the defendant, Melissa A. Huet, knowingly and unlawfully aided and abetted the possession of a firearm, that is an SKS assault rifle, in and affecting interstate commerce, by Marvin E. Hall, who had previously been convicted on or about March 12, 1999, in the United States District Court for the Western District of Pennsylvania ... of the crime of Possession of Unregistered Firearms, an offense which is punishable by a term of imprisonment in excess of one year. In violation of Title 18, United-States Code, Sections 922(g)(1) and 2.
In granting Huet’s Rule 12 motion, the District Court stated that “notably absent from the Indictment ... [were] any facts setting forth
how
defendant Huet aided and abetted defendant Hall in his unlawful possession of the SKS rifle.”
United States v. Huet,
No. 08-0215,
*594 The District Court’s view of the Government’s theory of the case similarly guided its approach to Huet’s Second Amendment challenge. Huet argued that even if Count Three did state an offense for aiding and abetting a felon in possession, under the factual scenario presented in this case, the charge violated her rights under the Second Amendment. The District Court agreed, finding that “to permit [the] Indictment to go forward ... would be [to] countenance] the total elimination of the right of a sane, non-felonious citizen to possess a firearm, in her home, simply because her paramour is a felon.” Id. at *11. “[T]o punish Huet, who has not been convicted of a felony ... as a principal, violates the core of the Second Amendment right to keep arms,” the Court opined, because the conduct alleged to have aided and abetted was “purely possessory.” Id. at *7; see id. at *11 (characterizing Government’s case as an attempt to “compound[] an inchoate offense upon another inchoate offense”). Although the District Court did not explicitly designate the Second Amendment violation as an alternative basis for dismissal, it clearly viewed it as such. Accordingly, we must address both the sufficiency of the Indictment and the Second Amendment challenge.
II.
The District Court had jurisdiction pursuant to 18 U.S.C. § 3231. We have jurisdiction over the District Court’s order dismissing the Indictment under 18 U.S.C. § 3731. “[W]hen reviewing a motion to dismiss an indictment, our standard of review is mixed.”
United States v. Shenandoah,
III.
A.
We first address the Government’s contention that the District Court erred in concluding that, under Federal Rule of Criminal Procedure 12(b)(3)(B), Count Three failed to state an offense for aiding and abetting a felon in possession of a firearm under 18 U.S.C. § 922(g)(1) and § 2.
1.
Federal Rule of Criminal Procedure 7(c)(1) requires only that an indictment “be a plain, concise, and definite written statement of the essential facts constituting the offense charged.” “[T]he Federal Rules ‘were designed to eliminate technicalities in criminal pleadings and are to be construed to secure simplicity in procedure.’ ”
United States v. Resendiz-Ponce,
“It is well-established that ‘[a]n indictment returned by a legally constituted and unbiased grand jury,
... if valid
*595
on its face,
is enough to call for trial of the charge on the merits.’ ”
United States v. Vitillo,
In determining whether an indictment validly states the elements of the offense, we need not blindly accept a recitation in general terms of the elements of the offense.
United States v. Panarella,
2.
To survive Huet’s motion to dismiss, the Government was required to adequately set forth the elements of aiding and abetting a felon in possession under 18 U.S.C. § 922(g)(1) and § 2. To establish a violation of 18 U.S.C. § 2, the government must prove: “(1) that the substantive crime has been committed; and (2) that the defendant charged with aiding and abetting knew of the commission of the substantive offense and acted with intent to facilitate it.”
United States v. Petersen,
In this case, we conclude that the Indictment adequately set forth the required elements under § 922(g)(1) and § 2, with “sufficient factual orientation” to allow Huet to prepare her defense and invoke double jeopardy.
See Kemp,
*597 We recognize that the .District Court may have adopted the novel procedure followed here to truncate what it perceived as an incurably weak Government case. However, in doing so, the District Court committed two errors: (1) it impermissibly expanded the scope of its review at the Rule 12 stage and evaluated the sufficiency of the evidence; and (2) it required the Government to meet a heightened pleading standard. We will discuss each of these issues in turn.
First, although the District Court purported to make a purely “legal” determination based on “undisputed” facts,
Huet,
Unlike other cases in which we have affirmed a district court’s dismissal of an indictment as insufficient, Huet’s case does not involve a question of whether the facts alleged in the indictment fall beyond the scope of the relevant criminal statute as a matter of statutory interpretation.
See Panarella,
Moreover, although we have left open the possibility that, in limited circumstances, a district court may be able to address the sufficiency of the government’s evidence in a pretrial motion to dismiss, this case does not present such a scenario.
See DeLaurentis,
Second, the District Court erred to the extent that it imposed a heightened pleading standard for offenses under 18 U.S.C. § 922(g)(1) and § 2. The District Court dismissed Count Three based on its determination that “[t]he facts in the Indictment fail[ed] to set forth
any
allegations to support the conclusion that ... Huet aided and abetted ... Hall in his unlawful possession of the SKS rifle.”
Huet,
In arguing for a heightened pleading standard, Huet attempts to distinguish the Supreme Court’s decision in
United States v. Resendiz-Ponce,
Moreover, the District Court’s suggestion that
Abuelhawa v. United States,
B.
1.
We turn now to Huet’s Second Amendment challenge. The Second Amendment provides: “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.” U.S. Const. amend. II. In
District of Columbia v. Heller,
Applying these principles, the Court invalidated a District of Columbia law that completely banned handgun possession in the home and required any lawful firearm to be kept disassembled and bound by a trigger lock at all times, rendering it inoperable.
Id.
at 628-35,
In United States v. Marzzarella, we articulated a two-step analysis for Second Amendment claims under Heller:
First, we ask whether the challenged law imposes a burden on conduct falling within the scope of the Second Amendment’s guarantee.... If it does not, our inquiry is complete. If it does, we evaluate the law under some form of means-end scrutiny. If the law passes muster under that standard, it is constitutional. If it fails, it is invalid.
Under the
Marzzarella
framework, the “presumptively lawful” regulatory measures identified by the Supreme Court in
Heller
carry the presumption of validity because they regulate conduct “falling outside the scope of the Second Amendment’s guarantee.”
United States v. Barton,
2.
The constitutional question here is presented in an unusual way due to the procedural posture of the case. The District Court’s characterization of Huet’s challenge as an as-applied attack is somewhat misleading. In contrast to a facial attack, an as-applied challenge “does not contend that a law is unconstitutional as written but that its application to a particular person under particular circumstances deprived that person of a constitutional
*601
right.”
United States v. Marcavage,
Huet argues that based on the circumstances of her ease, she cannot constitutionally be charged with aiding and abetting a felon to possess a firearm. Specifically, she contends that the Government’s only evidence is that she possessed the SKS rifle in her home while living -with a convicted felon. The District Court agreed, finding that “to permit [the] Indictment to go forward” would be to “countenance[e] the total elimination of the right of a sane, non-felonious citizen to possess a firearm, in her home, simply because her paramour is a felon.”
Huet,
We disagree. We cannot say that an indictment which properly alleges aiding and abetting a felon in possession under 18 U.S.C. § 922(g)(1) and § 2 violates the Second Amendment under
Heller.
Applying
Marzzarella,
a properly-brought aiding and abetting charge does not burden conduct protected by the Second Amendment.
See
Huet’s argument that her status as a non-felon brings her case within the scope of Second Amendment protection is unavailing. Relying on our decision in
United States v. Barton,
Because the conduct alleged in Count Three is beyond the scope of Second Amendment protection, our inquiry under
Marzzarella
is complete.
See
Our primary concern in
Marzzarella
was one of line-drawing, specifically, whether a firearm with an obliterated serial number was a “dangerous and unusual weapon.”
Huet’s case presents no line-drawing problem. Because § 922(g)(1) and § 2 do not restrict the right of possession of the aider and abettor, Count Three simply does not implicate Huet’s rights under the
*603
Second Amendment. Thus, unlike the restriction at issue in
Marzzarella,
we do not have to broaden any of
Hellers
presumptively valid categories to find that the conduct alleged in Count Three is outside the scope of Second Amendment protection.
See Marzzarella,
IV.
For the foregoing reasons, we will reverse the order of the District Court granting Huet’s motion to dismiss and remand for further proceedings. We hold that: (1) Count Three was sufficient to state an offense for aiding and abetting a felon in possession under 18 U.S.C. § 922(g)(1) and § 2; and (2) Count Three does not violate the Second Amendment.
Notes
. Section 922(g)(1) states:
It shall be unlawful for any person — who has been convicted in any court of, a crime punishable by imprisonment for a term exceeding one year ... to ship or transport in interstate or foreign commerce, or possess in or affecting commerce, any firearm or ammunition; or to receive any firearm or ammunition which has been shipped or transported in interstate or foreign commerce.
. Section 2(a) states: “Whoever commits an offense against the United States or aids, abets, counsels, commands, induces or procures its commission, is punishable as a principal.”
. Rule 12(b)(3)(B) provides: "[A]t any time while the case is pending, the court may hear a claim that the indictment ... fails to ... state an offense.”
. The affidavit provides, in pertinent part:
Huet indicated that she was angry that Hall had been showing off an SKS assault rifle. Huet said that if it happened again, she would take it "back” to Morgan. Huet further elaborated that she was worried that if Hall "gets in trouble with that, I get in trouble too. Cause it’s in my name, and he's got it.”
.At Hall's guilty plea hearing, the Assistant U.S. Attorney stated:
Mr. Hall lived with ... Melissa Huet, ... [who] had no prior record of which we are aware, but ... bought firearms in her name for Morgan Jones, who on the side sold firearms.... Miss Huet would allow Mr. Hall to have access to those firearms. In essence, that’s the very basis of the charge against Mr. Hall.
. Because we conclude that the Indictment should not have been dismissed, we do not address whether the District Court abused its discretion by dismissing the Indictment with prejudice.
. The only potential question of statutory interpretation — whether the SKS rifle was a "dangerous” or "unusual” firearm — was determined by the District Court when it took judicial notice of the fact that the SKS rifle was not an “assault weapon," but instead had been designated as a “curio” by the Bureau of Alcohol, Tobacco, and Firearms, and was used primarily by hunters and collectors.
See United. States v. Huet,
No. 08-0215,
. Although DeLaurentis indicated that there is an exception to the general rule barring district courts from considering the sufficiency of the evidence at the Rule. 12 stage, we have never explicitly held that such an exception *598 exists, much less defined its contours. We decline to do so now. We simply hold that, assuming an exception exists for cases involving a stipulated record or immunity issues, the circumstances of this case do not trigger it.
. We note that there is a split among our sister circuits as to whether a district court is ever permitted to rule on a motion to dismiss based on the sufficiency of the evidence. Some courts have indicated that in “rare” and “unusual” cases, it may be appropriate for a court to look to the sufficiency of the evidence.
See, e.g., United States v. Levin,
. In
McDonald v. City of
Chi., - U.S. -,
. Although some of our sister circuits have classified the "presumptively lawful” language in
Heller
as dicta,
