NFA Weapon – What You Need to Know
Federal firearms charges carry some of the harshest penalties in the entire federal system. Calculate sentencing for unregistered NFA weapons (machine guns, silencers, SBRs).
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 NFA Weapon
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.
Why You Need the Right Federal Defense Attorney
Federal firearms cases have mandatory minimums, consecutive sentencing requirements, and guideline calculations that can produce devastating results for defendants who don’t have experienced representation. 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 items require NFA registration under 26 U.S.C. § 5861, and what are the penalties for violations?
The National Firearms Act requires registration and a $200 tax stamp for machine guns, short-barreled rifles (barrel under 16"), short-barreled shotguns (barrel under 18"), suppressors/silencers, destructive devices, and "any other weapons" (AOWs, $5 tax). Possession of an unregistered NFA item under § 5861(d) carries up to 10 years imprisonment and a $250,000 fine. Under USSG § 2K2.1, the base offense level for NFA violations starts at 18-22 depending on the weapon type — significantly higher than standard firearms offenses. Defense counsel should challenge the ATF's classification of the item, as the definition of "short-barreled rifle" versus "pistol" depends on the weapon's original configuration and intended design, which can be genuinely ambiguous.
How does the "constructive possession" doctrine apply to NFA items found in shared spaces?
Constructive possession of NFA items requires proof that the defendant had knowledge of the item and the ability to exercise dominion and control over it. In cases where NFA items are found in shared residences, vehicles, or storage units, the government must prove more than mere proximity — there must be a nexus connecting the specific defendant to the item. Defense counsel should present evidence of other individuals with equal or greater access to the location, the absence of the defendant's fingerprints or DNA on the item, and the lack of any purchase records or internet search history linking the defendant to NFA items. The knowledge element is particularly important: the defendant must have known both that the item existed and that it was an NFA-regulated weapon.
