Q Shorty Stock Mil-Spec Black

The Q Shorty Stock Mil-Spec Black is a compact receiver extension assembly engineered for mil-spec AR-15 and M4 platforms. Designed as a drop-in replacement for standard carbine stocks, this shorty configuration reduces overall length while maintaining full operational compatibility with mil-spec bolt carrier groups and receiver extensions. The shortened profile makes it ideal for configurations where space is at a premium—vehicle-mounted systems, entry teams working in confined spaces, and shooters who prioritize handling speed over maximum sight radius.

This complete assembly ships with all necessary components: the stock itself, recoil spring, 3 oz buffer (tuned for 5.56 and .300 Blackout), and assembly tool. Total weight is 14.5 ounces including spring and buffer, keeping your upper receiver system light without sacrificing reliability. Installation requires standard tools—a torque wrench capable of 35 foot-pounds, 3/4-inch drive socket, Blue Loctite, mag-well vice block, and bench vise—making field replacement feasible for operators comfortable with basic armorer-level maintenance.

The mil-spec designation confirms adherence to military technical standards for receiver extension geometry, buffer tube diameter, and spring rates. This ensures compatibility across any mil-spec lower receiver and upper receiver pairing, whether commercial, military-surplus, or new manufacture. The black finish resists light corrosion in field environments, though regular maintenance remains essential for systems exposed to moisture or salt air. Best suited for duty applications, training platforms, and builds where compact length and proven mil-spec compatibility outweigh extended cheekweld considerations.
