Not a fan of the original A2 style grip? Upgrading your pistol grip on your rifle or pistol is as simple a process as just unscrewing your old grip and screwing in your new grip! If you're looking for a better texture, finger grooves, a rubber overmold, or even a beavertail to fill up your hand. You can certainly find a grip that works for you! The Pistol Grip houses a critical component in the function of your lower receiver, the safety selector spring. This spring applies pressure against your safety selector holding it in place and making the tactile 'click' when switching between safe and fire. Thanks to the interchangeability between AR-15 and AR-10 rifles, the pistol grip for an AR-15 can be used on both DPMS Pattern LR-308 rifles and AR-10 battle rifles.
