Sig Sauer MCX Rattler Upper 5.56 NATO Conversion Kit, 5.5″ Barrel. This upper Sig Sauer MCX Rattler AR 5.56 NATO conversion kit with a 5.5″ barrel length comes with everything needed to put on any standard MIL-SPEC AR lower. This conversion kit includes: a 1/2″ x 28 threaded barrel, a complete bolt carrier group, a Sig Sauer MCX upper, side folding AR buffer tube knuckler, and an AR Two-Stage Matchlite DUO trigger kit. The SIG Matchlite Duo trigger unit provides a crisp and clean feel, and a new tapered bolt lug design extends bolt life while resulting in smoother cycling. The MCX Rattler upper receiver assembly features a standard free-floating M-LOK handguard with a top picatinny rail for sight and optic, as well as a short-stroke piston system and unique internal recoil system that eliminates the M4-style buffer tube resulting in a light-recoiling and compact platform able to be configured for any task.
