Frequently Asked Questions

What are the penalties for possessing illegal firearm modifications like auto sears or solvent traps?

Possessing unregistered NFA items such as auto sears, Glock switches, or solvent traps functioning as suppressors can lead to severe federal felony charges, including up to 10 years in prison and fines of $250,000 per violation.

Are pistol braces legal? What are the risks associated with them?

The legality of pistol braces has been complex due to fluctuating ATF rules. When used to convert a pistol into a Short-Barreled Rifle (SBR), they require NFA registration and a tax stamp. Failure to comply can result in felony charges.

What constitutes an illegal modification under the National Firearms Act (NFA)?

The NFA regulates items like machine guns, short-barreled rifles (SBRs), short-barreled shotguns (SBSs), silencers, and Any Other Weapons (AOWs). Modifications that turn a legal firearm into one of these NFA-regulated items without proper registration and tax payment are illegal.

Can I modify a magazine to hold more than 10 rounds?

In many states, including California, New York, and Washington, modifying or possessing magazines that exceed the legal capacity limit (often 10 rounds) is illegal. These restrictions are upheld as regulations on firearm components.
