A Magpul MOE SL-M stock on a 1913 side-folding hinge, a free-float M-LOK handguard, and installed folding backup iron sights round out this NFA-regulated SBR.

    This MCX-SPEAR is a factory short-barreled rifle chambered in 7.62x51 NATO with a 13 in barrel, regulated under the NFA. The short-stroke gas piston system works with a two-position adjustable gas regulator, which includes a clear "SUPPRESSED" indicator on the handguard for quick reference.

    Controls are fully ambidextrous, including the safety selector and magazine release. Dual charging handles—one at the rear and a left-side non-reciprocating handle—offer flexible manipulation. A flat-faced, two-stage match trigger provides a consistent break. Length of pull is 12.5 in.

    The barrel uses a 1:10 twist and a 5/8-24 threaded muzzle fitted with a three-prong flash hider. The free-float M-LOK handguard and full-length Picatinny top rail provide mounting space for accessories as needed. Installed folding backup iron sights are included.

    Furniture includes a Magpul MOE SL-M stock mounted on a 1913 side-folding hinge with collapsible adjustment. The rifle is finished in coyote tan, with a capacity of 20+1 and one included 20-round Lancer L7AWM magazine.
