Recoil Reducing AR-15 Buffer Kit

Bravo Company’s MK2 Recoil Mitigation System effectively reduces recoil with a few changes to key components. This kit uses a longer, 8 position buffer tube, as well as a buffer containing 4 sliding weights, rather than the usual 3. Along with an M16A4 rifle buffer spring, this kit reduces velocity in the action, and provides an easier, steadier recoil impulse.

These complete kits come in a variety of weights for different builds. We also have additional weights for heavier buffers here.

Does It Actually Work?

In a word, yes. Ask anyone who has run a VLTOR A5 recoil assembly – the idea is much the same here. By increasing the load of the buffer spring, extending travel of the buffer, and upgrading the weight, this system effectively mitigates felt recoil compared to a short carbine buffer assembly. The buffer weight actually includes a spring as well, ensuring the increased mass reciprocates properly.
