TROY's M7A1 PDW Stock kit is the highly anticipated retractable stock made to elevate 5.56 carbines making them compact by 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 allows full access to operating features with a gloved hand and 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 a fluid motion. TROY's PDW Stock has 6 positions of adjustment and built-in sling mounts, making it the total package. Kit includes PDW Stock, spring and buffer system. Available in Black and FLat Dark Earth. Patents pending.
