The BCM MK2 represents a thoughtful approach to managing recoil energy in the AR platform. This complete assembly arrives ready to install, making it suitable for both new builds and existing rifle upgrades.
The system works by optimizing the relationship between buffer weight and spring rate, resulting in noticeably reduced felt recoil without sacrificing the reliability that AR shooters depend on. In fact, the design improves overall system reliability through better bolt carrier group cycling.
This is a complete kit—no additional components needed. It fits any standard AR-pattern rifle and installs in place of your existing buffer tube assembly. The 8-position adjustable design allows you to fine-tune your setup for different ammunition types or shooting applications.
Whether you're building your first AR or optimizing a trusted rifle, managing recoil improves accuracy, reduces fatigue, and makes shooting more enjoyable. The BCM MK2 delivers these benefits without compromise.
