The TROY M7A1 PDW Stock kit is the anticipated retractable stock made to elevate 5.56 carbines, making them compact, measuring 3” shorter than traditional carbine stocks. Utilizing a proprietary, patent pending spring, bolt carrier system and heavy duty latch assembly, the refined design makes the M7A1 PDW Stock Kit rugged, reliable and sturdy. The design of the rods in the TROY PDW stock allows full access to operating features, even with a gloved hand, and even when the stock is completely retracted. After depressing a lever on the underside of the stock with their thumb, operators can extend the stock in one fluid motion. TROY’s stock has 6 positions of adjustment and built-in sling mounts, making it the total package. Stock kit includes PDW Stock, spring, complete proprietary bolt carrier group and buffer system. Available in Black and Flat Dark Earth. Full auto capable. Will work with 300 Blackout. For direct impingement weapons only (non-piston operated weapons). Patent Pending.
