Arсhie Roy Jackson and James Bernis Midkiff were convicted of charges stemming from a conspiracy to manufacture and distribute methamphetamine. Jackson challenges the district court’s denial of his motion to suppress evidence found during a search in and around his home. Midkiff contends that the district court erred by increasing the quantity of drugs attributable to him for sentencing purposes and allowing the government to amend the indictment.
I
Jackson and Midkiff were indicted by а federal grand jury for their participation in a conspiracy to manufacture and distribute methamphetamine. They, along with several co-conspirators, utilized a number of remote rural locations in Louisiana to set up methamphetamine labs. They used these labs to “cook” methamphetamine, which they later distributed. In addition to the drug crimes, both men were accused of knowingly possessing a firearm in furtherance of a drug trafficking crime in violation of 18 U.S.C. § 924(c). Midkiff also was charged with being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1). Federal arrest warrants were issued for both men.
*239 Before Jackson was arrested, the state case agent in the federal investigation sought a search warrant for Jackson’s residence from a state court judge. The agent executed an affidavit supporting the warrant application, and, based on the affidavit, the state court issued a search warrant for Jackson’s residence.
Thus, at the time the officers went to Jackson’s residence, they had both a state search warrant and a federal arrest warrant. When the officers entered Jackson’s home, they observed him place something under the couch on which he was sitting. They quickly arrested Jackson and then conducted a sweep of the home to ensure that no one else was present. They also examined the couch and disсovered that the item Jackson placed under it was a bag of marijuana.
The officers continued their search of the residence and the outdoor area surrounding the home. Inside the house, they discovered a locked safe. Jackson provided the officers with the combination to the safe, inside of which they found guns and some crushed pseudoephedrine tablets, which are used to produce methamphetamine. Outside the house, they fоund chemicals and equipment used in the manufacturing of methamphetamine.
Before trial, Jackson filed a motion to suppress the evidence discovered during the search of his home. The district court denied the motion. Following a jury trial both Jackson and Midkiff were convicted of, inter alia, conspiracy to distribute methamphetamine, establishment of manufacturing operations, and attempt to manufacture methamphetamine. The jury indicated on a spеcial jury form that it found Jackson and Midkiff guilty of a conspiracy involving 50 grams or less of methamphetamine, but not guilty of a conspiracy involving 50 to 500 grams or 500 grams or more. Midkiff was also convicted of the firearms violations.
The United States Probation Officer issued a presentence report (“PSR”) attributing 1,318 grams of methamphetamine to Midkiff based on extrapolation from estimates provided by co-conspirators. Midkiff filed an objection to the PSR “in its entirety,” along with two other objections that are not relevant to the appeal. The Probation Officer responded to the objection, and the district court credited the response as adequate. The court adopted the factual statements in the PSR and found that it reasonably addressed the relevant conduct and accurately reported the applicable statutory sentences. In accordance with the Sentencing Guidelines, the cоurt sentenced Midkiff to 168 months for the drug crimes and 360 months for the gun crimes, to run consecutively. 1

Jackson argues that the district court erred when it denied his motion to suppress evidence found in and around his home during a search authorized by a state search warrant. He contends that the affidavit supporting the search warrant was based on incorrect and incomplete information, thus rendering the good-faith exception to the exclusionary rule inappliсable. He also argues that the search cannot be justified by the protective sweep rule because most of the evidence was found in the yard and not in the house itself.
We accept a district court’s factual findings on a motion to suppress
*240
based on live testimony at a suppression hearing “unless clearly erroneous or influenced by an incorrect view of the law.”
United States v. Foy,
Although the parties’ briefing primarily addresses the good-faith exception, our examination of the record does not indicate that the district court based its decision to deny Jackson’s motion to suppress on the good-faith exception. Before ruling on the motion, the district court heard testimony from the officer who provided the affidavit suрporting the search warrant and from one of the officers who conducted the search. After hearing argument from counsel, the district court stated:
[T]he ruling of the court is going to be [that] it’s not a bare bones affidavit. But I think that if it were based on the affidavit alone, it would be suppressed. However, I do agree with the government in this particular case that the inevitable discovery doctrine works. I also think that you’ve got the independent source verification by the officer who sees the marijuana when he comes into the residence, and he was a different officer from Officer Ortiz, in any event. So I think those two doctrines allow this particular search, that the items seized to be admissible, and so the motion to suppress in this case will be overruled on that basis.
Based on this oral ruling, it is unclear whether the district court found that the good-faith exception applied. 2
What is clear, however, is that the district court based its ruling at least in part on the inevitable discovery doctrine. Because of this alternate grounds for denying the motion to suppress, we do not reach the merits of the good-faith exception argument. Instead, we analyze the district court’s determination that the evidence from the search of Jackson’s home and the surrounding areas is admissible under the inevitable discovery doctrine.
See United States v. Grosenheider,
*241
“The exclusionary rule of the Fourth Amendment generally prohibits the introduction at trial of not only primary evidence obtained as a direct result of an illegal search or seizure, but also evidence discovered later that is derivative of an illegality, or constitutes ‘fruit of a poisonous tree.’ ”
Grosenheider,
The inevitable discovery rule applies if the Government demonstrates by a preponderance of the evidence that (1) there is a reasonable probability that the contested evidence would have been discovered by lawful means in the absence of police misconduct and (2) the Government was actively pursuing a substantial alternate line of investigation at the time of the constitutional violation.
United States v. Lamas,
It is undisputed that, even without the state search warrant, the federal arrest warrant gave the officers the authority to enter Jackson’s residence to arrest him.
See Payton v. New York,
In addition to the marijuana, the officers found equipment and other materi
*242
als used in the manufacturing of methamphetamine outside the house. Because these items were located in the area surrounding the residence and the officers had authority to enter this area as they executed the arrest warrant, they could be seized pursuant to the plain view doctrine, which allows police to sеize items without a search warrant. Such a warrantless seizure is permissible if: (1) the police lawfully entered the area where the item was located; (2) the item was in plain view; (3) the incriminating nature of the item was “immediately apparent;” and (4) the police had a lawful right of access to the item.
United States v. Buchanan,
In this case, the officers did not seek a search warrant based on the evidence which could have been seized pursuant to the arrest warrant because they already had a state search warrant. But, had they had reason to question the validity of the state search warrant or had there been no state search warrant, we have little doubt that the officers nonetheless could have secured a search warrant and conducted the sеarch that yielded the disputed evidence.
As to the second requirement for invoking the inevitable discovery doctrine, it almost goes without saying that the government was actively pursuing a substantial alternate line of investigation at the time of the alleged constitutional violation.
Lamas,
Jackson’s only argument addressing whether the evidence would have been inevitably discovered without the allegedly improper state search warrant focuses on the protective sweep that was conducted contemporaneously with the arrest. Jackson argues that the protective sweep could nоt legitimize the search because many of the seized items were found outside the house, and thus outside any area the police might reasonably have searched to ensure their safety. Regardless of the merits of this argument, there are, as discussed, other grounds supporting the application of the inevitable discovery doctrine. Jackson has waived any challenges to these other grounds by failing to address them in his briefing.
See Goodman v. Harris County,
In conclusion, because the police would have inevitably discovered the evidence even had the state search warrant never issued, it need not be suppressed. The exclusionary rule is meant to put the police “in the same, not a worse, position than they would have been in if no police error or misconduct had occurred.”
Nix v. Williams,
*243 III
Midkiff presents two arguments on appeal. First, Midkiff contends that the district court erred in relying on the PSR’s recommendations in making its sentencing determinations because the PSR relied on a quantity of drugs that had not been submitted to the jury and proved beyond a reasonable doubt in accordance with
Apprendi v. New Jersey,
A
On a special jury form, the jury found Midkiff and his co-conspirators guilty of conspiracy to distribute 50 grams or less of methamphetamine, but not guilty of conspiracy to distribute 50 to 500 grams or 500 grams or more. Nonetheless, the Probation Officer attributed 1,318 grams of methamphetamine to Midkiff based on extrapolation from estimates provided by co-conspirators. This increased Midkiffs base offense level by at least eight. See U.S.S.G. § 201.1(c). Midkiff objeсted to the PSR “in its entirety,” but did not specifically object to the amount of methamphetamine attributed to him. He now argues that the entire PSR was tainted by the preparer’s subjective belief, which conflicted with the unanimous findings of the jury regarding drug quantity.
It is unnecessary to decide whether to apply our typical standard of review or plain error review because both our precedent and Supreme Court precedent foreclose Midkiffs argument regardless of the standard we apply. We have held that a “district court correctly calculated the quantity of drugs [for sentencing purposes] notwithstanding the fact that the jury specifically acquitted [the defendant] of the large drug quantities later found by the judge.”
United States v. Pineiro,
“In making its factual findings for sentencing, a district court may adopt the findings of the PSR without additional inquiry if those facts have an evidentiary basis with sufficient indicia of reliability and the defendant does not present rebuttal evidence or otherwise demonstrate that the information is materially unreliable.”
United States v. Ford,
Finally, we note that Midkiffs sentence of 168 months imprisonment on the drug conspiracy count is less than the maximum sentence authorized by the jury’s verdict.

We have previously found no
Apprendi
еrror where a district court determined the quantity of drugs under the preponderance of the evidence standard and sentenced the defendant to a term of imprisonment within the statutory range authorized by the jury’s verdict.
See United States v. Doggett,
B
Midkiff also argues that his convictions for possession of a firearm in furtherance of a drug trafficking crime and possession of a firearm by a convicted felon should be reversed because the serial number provided in the indictment for the firearm at issue was not the same as the serial number for the firearm introduced as evidence at trial. He argues that the district court erred by permitting an amendment to the indictment after the close of all evidence, particularly when the government had knowledge of the discrepancy early in the trial, if not earlier, and failed to move to amend until evidence was closed.
Generally, indictments can only be amended by a grand jury.
United States v. Adams,
Although we have never addressed this question directly, precedent from this circuit and others suggests that the particular attributes of a firearm are not actual elements of the offеnse.
See, e.g., United States v. Munoz,
We also have noted that “[a]n amendment will be allowed if a defendant’s rights are not affected and he is adequately apprised of the charges against him so that he is protected against surprise at trial .... ”
Young Bros.,

In conclusion, we find the appellants’ arguments unavailing and affirm the convictions. We also find no error in Midkiffs sеntence.
AFFIRMED.
Notes
. Because Jackson does not challenge his sentence, we limit our discussion of sentencing to Midkiff.
. On the one hand, a determination that the affidavit is more than "bare bones” is relevant to determining good faith. See
United States
v.
Cisneros,
. The independent source doctrine cases are applicable in this context because the two doctrines "are actually two sides of the same coin.”
Grosenheider,
. We previously have held that
Watts
remains valid after
United. States v. Booker,
. Because on his prior felony drug conviction, Midkiff was subject to an enhanced penalty of 30 years imprisonment on the conspiracy charge. See 21 U.S.C. § 841(b)(1)(C).
