Case Summary

Disposition

Reversed in Part

Smith pled guilty to possessing a machinegun but challenged both the constitutionality of 18 U.S.C. § 922(o) and a four-level Sentencing Guidelines enhancement for having a firearm with a modified serial number. The Fourth Circuit upheld his conviction, found § 922(o) constitutional, but reversed the serial-number enhancement, holding it applies only when all serial numbers are illegible, vacating his sentence and remanding for resentencing.

Legal Issue

Whether the four-level enhancement in U.S.S.G. § 2K2.1(b)(4)(B)(i) applies when only one of multiple serial-number markings on a firearm is rendered illegible, or whether the firearm must be rendered wholly untraceable (all serial numbers illegible).

Circuit Positions

Circuit 1Circuit 2Circuit 3Circuit 5Circuit 6Circuit 8Circuit 11

Enhancement applies if any one serial-number marking is illegible or unrecognizable (no requirement that all markings be obliterated).

Circuit 4(this circuit)

Enhancement applies only if all serial-number markings are illegible, rendering the firearm untraceable.

Conflict Summary

Most circuits hold that the enhancement is triggered so long as any single serial-number marking on the firearm is altered, even if other markings remain legible. The Fourth Circuit, in this opinion, holds that the enhancement applies only when every serial-number marking has been modified so that the firearm is no longer traceable, adopting a traceability requirement the other circuits reject.
