When a champion PCC shooter like Lena Miculek runs a gun in competition, you know its serious. That's why the SIG Sauer MPX PCC is definitely worth a look for fans of pistol-caliber carbines. This gun is built to run. Each SIG Sauer MPX PCC starts with the same bombproof operating system that made the MPX so popular with professionals and civilians across the world. Added to that durable, reliable operating system are a few enhancements, like the Timney MPX trigger, a trimmed-down, slim, M-LOK handguard, a folding stock adjustable for overall length and a recoil-reducing compensator.
