UTG Standard Buffer for AR-15 / M-4 Carbines (2.9 ounces)
This buffer is made with an anodized aluminum housing and filled with three solid steel weights for a total weight of 2.9 ounces. This lighter weight buffer provides lower mass which helps ensure the bolt carrier consistently goes all the way to the rear and locks back on an empty magazine for guns that cycle more weakly. This is a simple, high quality upgrade to your AR operating system. A great compliment to any quality rifle and works well with our high quality Sprinco or JP recoil springs. If your gun cycles weakly or doesn't lock back properly and needs more bolt carrier velocity, you can pair this buffer with a Sprinco Standard Power Spring (white). If your system cycles with plenty of force, you can use this buffer with a Sprinco Extra Power Spring (red) for a low mass system that doesn't slam to the rear as hard and has more force to chamber a fresh round.
Weight: 2.9 ounces
Fits any AR-15 type weapon with a collapsable stock
