UTG H2 Heavy Buffer for AR-15 / M-4 Carbines (4.6 ounces)
This buffer is made with an anodized aluminum housing and filled with two solid tungsten weights and one solid steel weight. The heavy weight and increased mass slows down the bolt carrier's rearward movement and provides more mass for feeding the next round from the magazine. 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.
Weight: 4.6 ounces
Fits any AR-15 type weapon with a collapsable stock
Works with all AR-15 calibers including .223/5.56mm, 6.8 SPC, .300 AAC Blackout, 7.62x39mm, 6.5 Grendel, etc.
