Sillasse Bryan appeals from a judgment of conviction of the United States District Court for the Eastern District of New York (David G. Trager, Judge). Bryan was convicted on July 3, 1996, after a jury trial, of conspiring to engage in the sale of firearms without a license as well as actually engaging in the sale of firearms without a license in violation of 18 U.S.C. §§ 371, 922(a)(1)(A). The Court sentenced Bryan to a term of 57 months in prison and to supervision upon release for three years.
Bryan seeks reversal of his conviction on three grounds: first, that the jury had before it insufficient evidence upon which to convict him of the violations charged; second, that the court erred in failing to charge the jury properly with respect to the credibility of certain witnesses for the government; and, third, that the court erred in instructing the jury that an overt act not set forth in the indictment may constitute an act in furtherance of a conspiracy under 18 U.S.C. § 371. Each of these claims is without merit.
Bryan’s first contention is that the jury had insufficient evidence on which to convict him of the willfulness necessary under 18 U.S.C. § 922(a)(1). Defendant’s argument, however, rests on a misunderstanding of the law of this circuit. The willfulness element of unlawful sale of firearms does not require proof “that defendant had specific knowledge of the statute he is accused of violating, nor that he had specific intent to violate the statute.”
See United States v. Ali,
*92
With the proper understanding of the requirement of willfulness in this circuit, defendant’s insufficiency argument is unavailing. It is axiomatic that a defendant faces a heavy burden when challenging the sufficiency of the evidence to support a jury’s verdict.
See, e.g., United States v. Soto,
Defendant’s second argument on appeal concerns the court’s instructions regarding the credibility of two of the government’s witnesses, women who aided Bryan in purchasing firearms during his trips to Ohio. As an initial matter, we note that defendant’s counsel failed to object to the credibility charge given by the district court. Joint Appendix 128-29. Thus, notwithstanding the inclusion of the sought after charge in defendant’s proposed instruction submitted to the court, we review for plain error.
See, e.g., United States v. Wong,
Defendant’s first contention in this regard surrounds his unsuccessful efforts to have the court instruct the jury that two of the government’s witnesses w^ere drug abusers and that they were abusing drugs at the time certain events at issue allegedly occurred. Even assuming that refusal to give this instruction was error and was clear at the time — matters we seriously doubt — we cannot conclude that the district court’s refusal “affect[ed] substantial rights.” Fed. R.Crim.P. 52(b). In order for an error to affect substantial rights, “[i]t must have affected the outcome of the district court proceedings.”

*93 Defendant’s second contention regarding the district court’s charge to the jury is that the court’s instruction insufficiently addressed the conflict inherent in accomplice testimony. Here we find that the district court committed no error, let alone plain error. The district court took care to instruct the jury of the dangers of accomplice testimony and of the need to give the two witnesses’ testimony special attention because both had entered into cooperation agreements with the government. In part, the district court charged:
Because of the very nature of accomplice testimony ... it must be scrutinized with great care and viewed with particular caution when you decide how much of that testimony to believe. You should, for example, ask yourselves whether an accomplice witness would benefit more by lying or telling the truth.
Joint Appendix at 108. Moreover, after specifically identifying the government’s two accomplice witnesses and mentioning their plea agreements, the court instructed:
The government is permitted to enter into such agreements. But witnesses who testify pursuant to such agreements have an interest in this case different from an ordinary witness. This is why you must carefully scrutinize whether the testimony of such a witness was made up in any way because the witness believed or hoped that he would receive favorable treatment by testifying falsely.
Id. at 109. In light of this language, defendant’s contention that the district court erred is meritless.
Finally, defendant argues that the district court erred in charging the jury that an overt act not included in the indictment can constitute the foundation of a conspiracy conviction. Defendant’s argument fails. The court has specifically held that a conspiracy “conviction may rest on an overt act not charged in the indictment.”
United States v. Armone,
For the foregoing reasons, we find defendant’s arguments to be without merit. Accordingly, we affirm the judgment of the district court.
Notes
. This appeal was resolved by summary order on February 10, 1997. Upon request of the parties and because we conclude that publication is warranted, we issue this opinion which in substance restates and expands upon that order.
