Obliterated Serial Number – What You Need to Know
Federal firearms charges carry some of the harshest penalties in the entire federal system. Calculate sentencing for possessing firearms with altered serial numbers under 18 USC §922(k).
If you’re facing firearms charges, here’s what you need to understand: 18 USC §924(c) imposes mandatory consecutive sentences – 5 years for possession, 7 for brandishing, 10 for discharge – and these sentences run on top of any other sentence. A second §924(c) conviction carries 25 years to life. This is serious. But there are defenses, there are arguments, and there are strategies that an experienced federal defense attorney can use to fight for a better outcome.
How Federal Firearms Sentencing Works
The first question in any §924(c) case is whether the predicate offense qualifies as a “crime of violence.” After the Supreme Court’s decision in Davis v. United States (2019), many offenses that previously served as §924(c) predicates no longer qualify. This is a major development – and it means that §924(c) charges can sometimes be challenged and defeated entirely. Many attorneys don’t even raise this argument. We always do.
For felon-in-possession cases under §922(g), the guideline calculation under §2K2.1 depends heavily on your prior convictions. If you have a prior “crime of violence” or “controlled substance offense,” the base offense level jumps significantly. But the definition of these terms has been subject to extensive litigation, and what counts as a qualifying prior varies by circuit. You need an attorney who stays current on this case law – because it changes frequently.
The Armed Career Criminal Act (ACCA) adds another layer. If you have three qualifying predicate offenses, you face a 15-year mandatory minimum. But qualifying priors are determined using the categorical approach, which requires examining the elements of the prior offense – not the underlying facts. Many convictions that look like they qualify on the surface actually don’t when you apply the correct legal analysis.
What Most People Don’t Realize About Obliterated Serial Number
The biggest thing people miss in firearms cases is that §924(c) charges are negotiable. The difference between pleading to a §924(c) count and having the firearm reflected only in a guideline enhancement can be the difference between 5+ years of mandatory consecutive time and a 2-level increase. This is where experienced plea negotiation makes all the difference.
For felon-in-possession cases, constructive possession is often more defensible than people realize. The government has to prove you had knowledge, access, and dominion over the firearm. If the gun was found in a shared residence or vehicle, that’s not automatic possession – and a suppression motion challenging the search can sometimes eliminate the evidence entirely.

You need an attorney who understands the post-Davis landscape, knows how to challenge predicate offenses, and can negotiate effectively with federal prosecutors to eliminate or reduce the most damaging charges.

Frequently Asked Questions
What does "obliterated serial number" mean under 18 U.S.C. § 922(k), and how is constructive knowledge established?
Section 922(k) prohibits possession of a firearm with an altered, removed, changed, or obliterated serial number. The statute does not require complete obliteration — partial alteration that makes the number unreadable is sufficient. The government must prove the defendant knew the serial number had been altered, but courts accept constructive knowledge where the alteration was visible to the naked eye. Defense counsel should retain forensic firearms examiners to assess whether the alteration was actually visible without magnification, and whether factory defects, rust, or wear — rather than intentional removal — caused the illegibility. Post-Bruen challenges to § 922(k) have had mixed results, with courts generally finding historical analogues in founding-era requirements to mark weapons for identification.
How does a § 922(k) charge interact with other firearms offenses, and what is the sentencing impact?
Section 922(k) is frequently charged alongside § 922(g) (prohibited person) when a convicted felon possesses a firearm with an obliterated serial number. Under USSG § 2K2.1(b)(4), an altered or obliterated serial number adds a +4 level enhancement to any firearms offense, significantly increasing the guideline range. Defense counsel should challenge grouping — if the § 922(k) violation and § 922(g) violation involve the same firearm and single act of possession, they should be grouped under § 3D1.2 rather than treated as separate counts. The serial number enhancement applies even if the defendant did not personally remove the number, making the knowledge element critical for both the charge itself and the sentencing enhancement.
