Firearms Conspiracy Explained
When three men purchased identical Glock 19 Gen5 MOS pistols from separate dealers within 48 hours using sequential money orders, ATF investigators didn’t see coincidence—they saw conspiracy. Firearms conspiracy charges carry heavier penalties than individual gun crimes, often turning misdemeanors into 20-year felonies.
The Legal Definition
Under 18 U.S. Code § 371, firearms conspiracy occurs when two or more people agree to violate federal gun laws and take at least one overt action toward that goal. Unlike state straw purchase cases (typically misdemeanors), federal prosecutors need only prove:
- An agreement existed (can be implied)
- Defendant knew the illegal objective
- Any participant committed an overt act
Example: Person A buys a Sig Sauer P365 for Person B (a prohibited possessor), then Person B pays $100 extra—that’s conspiracy, not just a straw purchase.
Common Scenarios
ATF prioritizes these patterns for conspiracy charges:
- Straw purchasing rings: Multiple buyers acquiring FN 509 Tacticals or other high-demand models for traffickers
- Document fraud: Falsifying 4473 forms while coordinating with others
- Interstate trafficking: Moving Glock switches or unserialized “ghost guns” across state lines
In 2023, a Phoenix group faced conspiracy charges after purchasing 37 Taurus G3c pistols in 90 days—all later recovered at Mexican crime scenes.
Penalties vs. Standard Charges
Conspiracy charges compound existing violations:
| Charge | Max Penalty |
|---|---|
| Straw purchase (standalone) | 10 years |
| Conspiracy to straw purchase | 20 years |
| Lying on 4473 | 5 years |
| Conspiracy + 4473 fraud | 25 years |
Prosecutors often use conspiracy charges to pressure lower-level participants into testifying against ringleaders.
Defense Strategies
Effective defenses require disproving key elements:
- No agreement: Show purchases were independent (e.g., two friends buying S&W M&P15 rifles separately)
- No knowledge: Prove defendant was unaware of others’ illegal intentions
- Withdrawal: Document attempts to leave the conspiracy before crimes occurred
Note: Simply not completing the crime isn’t enough—you must actively withdraw and notify co-conspirators.
