This MPX comes new in the box but with a few enchantments. We have added Franklin Armory;s Binary Trigger which is a 3-Position Trigger. In position 3 it will fire 1 round on Pull and 1 round on Release. This makes it one of the fastest semi-automatic triggers on the market. The BFSIII is ideal for Tactical and Competition use. The BFSIII provides greatly reduced split times between rounds and the ability to place two separate shots into a tighter group. We have also added the SB Tactical MPX PSB. This is a 3 position adjustable brace deigned by veterans and made here in the USA. Lastly we have added our Texas Shooter’s Supply Iron Sights.
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.
