The LBE Unlimited H3 Carbine-Length Recoil Buffer (brand part no. ARBUFFH3) gives AR-15/M16 builders a heavier buffer weight to help tune bolt-carrier cycling and felt recoil on a carbine-length gas system. LBE Unlimited machines the buffer body from silver aluminum and adds three internal tungsten weights, bringing total weight to 5.6 ounces without changing the buffer’s standard carbine-length dimensions. Among our AR lower parts, this H3 buffer suits builders running a carbine gas system who want to slow bolt-carrier velocity for a softer, more controlled cycle.

Frequently Asked Questions

What does adding tungsten weight to a buffer do? It increases buffer mass, which slows bolt-carrier velocity and can reduce felt recoil and bolt bounce on a carbine gas system.

Does this fit a standard carbine buffer tube? Yes, it’s built to standard AR-15/M16 carbine-length dimensions.
