SIG MCX

Rare card · No. 33998

The SIG MCX is a family of rifles designed and manufactured by SIG Sauer, produced in both selective fire assault rifle configuration and semi-automatic only models. It features a short-stroke gas piston system, which is inherited from the earlier SIG MPX submachine gun. The semi-automatic only variant of the MCX is available in rifle, carbine, short-barreled rifle, and pistol (short-barreled rifle configured with a pistol brace or without a buttstock at all) configurations. The MCX served as the basis for SIG Sauer's NGSW-R submission, the SIG MCX-SPEAR, designed to chamber the .277 Fury cartridge, and was formally adopted as the M7 rifle by the U.S. Army in 2022.
