United States v. Jones, 927 F.3d 895 (5th Cir. June 21,
2019).

The Fifth Circuit affirmed the defendant’s 84-month sentence for being a felon in possession of a firearm, holding that the §2K2.1(b)(4) enhancement for an altered or obliterated serial number was warranted where the metal plate reflecting the serial number had been removed from the firearm’s frame but it had a legible serial number on its slide. Joining the First, Eighth, and Eleventh Circuits the court held that §2K2.1 requires that only one serial number be altered or obliterated even if others are clearly legible, and that a serial number is “altered or obliterated” when it is “materially changed in a way that makes accurate information less accessible.

Guideline § 2K2.1(b)(4) applies a four-level enhancement to a defendant’s base offense level “[i]f any firearm … had an altered or obliterated serial number.  In United States v. Perez, 585 F.3d 880 (5th Cir. 2009) the Fifth Circuit addressed the meaning of “altered or obliterated” and adopted the Ninth Circuit’s holding in United States v. Carter, 421 F.3d 909 (9th Cir. 2005) that “a firearm’s serial number is ‘altered or obliterated’ when it is materially changed in a way that makes accurate information less accessible. The Fifth Circuit held in Perez that an attempt to scratch the serial number off of a firearm made accurate information less accessible, even though the serial number was “actually readable.

The First Circuit noted that the guideline requires “only ‘an altered or obliterated serial number. U.S. v. Serrano-Mercado, 784 F.3d 838 (1st Cir. 2015) and reasoned that[a]pplying an enhancement for firearms that have a single totally obscured serial number may serve as a deterrent to tampering, even when incomplete. And, relatedly, the single-obliteration rule could facilitate tracking each component that bears a serial number, given that various parts of firearms may be severable.

The Fifth Circuit joined the First, Eighth, and Eleventh Circuits in holding that the applicable guideline “requires only that one serial number be altered or obliterated, even if others are clearly legible.
