SUMMARY ORDER
Sean Stuckey appeals from a judgment of conviction, following a six-day jury trial, for one count of possessing a firearm and ammunition, which had been shipped and transported in interstate commerce, after having been convicted of a crimé punishable by imprisonment for a term exceeding one year, and after having had three previous convictions for a violent felony, in violation of 18 U.S.C. §§ 922(g)(1), 924(e). Stuckey was sentenced to 188 months’ and ten days’ imprisonment, followed by five years of supervised release. We assume the parties’ familiarity with the facts and procedural history of this case, and the issues presented on this appeal.
Stuckey contends that the district court erred by not ordering a competency hearing sua sponte. After a careful review of the record, we conclude that the district court acted within its discretion in not deciding, on its own motion, that there was “reasonable cause to believe that the defendant [was] suffering from a mental disease or defect rendering him mentally incompetent to the extent that he [was] unable to understand the nature and consequences of the proceedings against him or to assist properly in his defense.” United States v. Quintieri,
Stuckey asserts that several statements evincing Stuckey’s knowledge of the presence of the gun and ammunition in his room were allegedly made in violation of the Miranda rule. See Miranda v. Arizona,
“Under the plain error test of Rule 52(b), before an appellate court can correct an error not raised at trial, there must be (1) error, (2) that is plain, and (3) that affects substantial rights. If all three conditions are met, an appellate court may then exercise its discretion to notice a forfeited error, but only if (4) the error seriously affects the fairness, integrity, or public reputation of judicial proceedings.” United States v. Vasquez,
Stuckey argues that the district court erred in admitting as evidence the gun, magazine clip, box of ammunition, and loose rounds of ammunition allegedly found in his room. This argument fails because, although a perfect chain of custody may not have been established, there was enough evidence of authenticity to permit a reasonable juror to conclude that the physical evidence admitted was the evidence found in Stuckey’s room. See United States v. Dhinsa,
Having reviewed the record, moreover, we find no support for Stuckey’s argument that there was insufficient evidence to convict him.
Stuckey’s argument that 18 U.S.C. § 922(g) is unconstitutional under Columbia v. Heller, — U.S. -,
Finally, we reject Stuckey’s argument that the district com't did not explain Stuckey’s sentence sufficiently to satisfy 18 U.S.C. § 3553(c). The district court gave an explanation of its reasons sufficient to enable us to review the propriety of the sentence.
For the foregoing reasons, the judgment of the district court is hereby AFFIRMED, except insofar as we hereby REMAND to the court for amendment of the judgment form as set forth above.
