Free NFA Gun Trust
- We offer a free NFA Gun Trust (a $250 value) to all customers which essentially establishes a joint ownership scenario in which you can legally share your silencer with designated others (as well as determining who will inherit your silencer). This lets others use your silencer.
- We do all the ATF paperwork which helps ensure you completed the gun trust correctly so ATF does not reject. We have completed over 15,000 silencer to gun trust transfers and counting! LEARN MORE
In the event you need you rifle barrel threaded to accept your new silencer, we will take care of that as well through our Threading Central. LEARN MORE
Unconventional design, unmatched performance, and familiar AR handling. The SIG MPX redefines the submachine gun category with a new level of operator safety, in-field adaptability and proven reliability in the harshest environments.
Completely ambidextrous, the SIG MPX is great for left- or right-handed shooters with its dual-sided selector switch, magazine release, charging handle and bolt release.
The SIG MPX operates from a fully-closed and locked rotating bolt, offering enhanced reliability and safety in use. A short-stroke gas piston allows the SIG MPX to run all weights and brands of 9mm ammunition with no adjustments to the gas valve.
A full-length picatinny rail allows for solid, consistent mounting of optics and targeting lasers.
