The Sig MCX is engineered from the ground up to be silenced, light, and short. With an innovative short-stroke gas piston operating system, users can change barrels, calibers, stocks, and handguards in the field. Hardened and replaceable upper receiver wear points, ambi AR-style controls, and backward compatibility with legacy AR lower receivers. The SIG MCX eclipses everything that has preceded it. This PDW SBR version features a 9" barrel with a skeletonized folding stock, further reducing weight, while not sacrificing stability.
