BCM MK2 Buffer Weight for MK2 AR-15 Receiver Extensions

Bravo Company MK2 Buffer with 4 Sliding Weights

The Bravo Company MK2 Buffer weight for their specialized MK2 Receiver Extension is an upgrade over standard AR-15 buffers. Each buffer contains four sliding weights, along with an internal flat wire spring to ensure even reciprocation of mass. When combined with the MK2 Receiver Extension and an AR-15 Rifle length recoil spring, this buffer effectively reduces recoil.

You can also find MK2 Buffer kits here, with options for T0, T1, and T2 buffers included.

Note: MK2 Buffers are proprietary to MK2 Receiver extensions. Do NOT use MK2 Buffers in standard carbine buffer tubes!

What Do These Weights Mean?

Each choice of buffer weight corresponds to how many of the internal weights are steel or tungsten. T0 means that there are no tungsten weights inside the buffer; it’s all steel. T2 means that there are 2 tungsten weights, and 2 steel weights. This range allows you to fine-tune your rifle to effectively tame recoil from almost any amount of over-gassing.
