LBE Unlimited AR-15/M16 H2 Carbine Buffer – Aluminum

The LBE Unlimited H2 Heavy Carbine Buffer is a carbine-length recoil buffer engineered for AR-15/M16 platforms. It uses two tungsten weights and one steel weight to add mass and slow the bolt carrier group for more controlled cycling. Constructed with an aluminum body and supplied specifically for carbine buffer tubes, the buffer is intended for tuning cycling characteristics based on gas system and ammunition. The unit is a direct-fit carbine-length component from LBE Unlimited.
