The DT-PR stock is the Precision Rifle (PR) variant of our new Dual-Tension (DT) series of carbine stocks. It incorporates Magpuls proprietary, patent-pending DT adjustment system, mitigating play between the buffer tube and the stock, resulting in a tighter fit across the stocks entire length of pull. It also minimizes snagging of facial hair and skin where the shooters face contacts the stock. | Magpul MAG1447BLK DT-PR Carbine Firearm Stock
