Firearm Offenses: What Sentences Really Look Like
A first-time offender caught with an unregistered Glock 19 faces 18 months minimum in federal prison—no plea deals, no probation. That’s the reality under 18 U.S.C. § 924(c), and it’s why every gun owner needs to understand sentencing guidelines before making a single move with their firearm.
Federal Mandatory Minimums for Firearms
The federal system doesn’t play games with gun crimes. Get caught using a firearm during a drug trafficking offense or violent crime? That’s an automatic 5-year federal sentence tacked onto your existing charges—7 years if it’s a short-barreled rifle, 10 for machine guns. The ATF specifically targets cases involving modified triggers or auto-sears, like the FRT-15 that’s been making headlines. At FRTforsale, we stress legal compliance because these cases get prosecuted to the fullest extent.
State vs. Federal Firearm Charges
State penalties vary wildly. Texas gives probation for first-time unlawful carry (PC §46.02), while California slaps felonies for magazine capacity violations (PC §32310). But cross state lines with that same gun? You’re now looking at federal interstate transportation charges under 18 U.S.C. § 922(a)(3). Recent cases show prosecutors stacking state and federal charges—we’ve seen AR-15 builds land 15-year sentences when state “assault weapon” bans intersect with federal paperwork errors.
Enhancements That Add Years
Three factors turn misdemeanors into decade-long sentences: prior convictions, drug proximity, and modifications. A Hi-Point C9 with a scratched-off serial number gets you 2 years. That same gun within 1,000 feet of a school zone? 5 years minimum. Add a homemade suppressor or binary trigger, and you’re facing 10-15 under the NFA. The DOJ’s current priority is prosecuting unserialized “ghost guns,” with sentences running consecutively for each illegal firearm possessed.
Plea Bargains in Gun Cases
Unlike drug cases, firearm offenses rarely get reduced charges. Federal prosecutors routinely reject plea deals for crimes involving:
- Machine gun conversion devices (like Glock switches)
- Straw purchases tracked via Form 4473
- Felons in possession (even antique firearms)
The only reliable mitigation is proving the firearm was legally purchased—which is why FRTforsale provides full documentation with every transfer.
FAQs on Firearm Offense Sentencing
What are firearm offences?
Firearm offenses range from unlawful possession (like felons with guns) to trafficking and illegal modifications. Federal law defines these under Title 18, while states add their own restrictions like magazine bans or assault weapon laws.
Can you get probation for a gun charge?
Only in rare state cases for first-time misdemeanors. Federal gun charges carry mandatory minimums—probation isn’t an option for crimes like possession by prohibited persons or NFA violations.
Do background check errors affect sentencing?
No. “I didn’t know I was prohibited” isn’t a defense. Even if the NICS system fails, you’re still liable for unlawful possession under 18 U.S.C. § 922(g).
