The BCM MK2 Buffer Mod 1 T2 (brand part number BCM-BFMK2-M1-T2) is a 5.6-ounce tuning buffer from Bravo Company built as a standalone upgrade for AR-pattern rifles already running the MK2 Recoil Mitigation System. It exists to let a shooter fine-tune reliability and ejection pattern on a rifle that’s running over-gassed, whether that’s from a suppressor, a short barrel, or an adjustable gas block set too far open. The T2 weight sits at the heavier end of BCM’s MK2 buffer options, giving the system more mass to work with when a rifle needs extra dwell time to cycle cleanly.

Key Specifications

• Weighs 5.6 ounces, positioned as a heavier tuning weight within the MK2 buffer lineup.
• Designed as a standalone upgrade for rifles already running the BCM MK2 Recoil Mitigation System.
• Lets the shooter fine-tune ejection pattern and reliability on an over-gassed rifle, suppressed or unsuppressed.
• The T2 designation marks it as a heavier tune option compared to lighter buffers in the same MK2 line.
• Requires an existing MK2 Recoil Mitigation System; it is not a standalone buffer for a standard mil-spec buffer tube.

Frequently Asked Questions

Can I use this buffer in a standard AR buffer tube without the MK2 system? No. BCM specifies this buffer as an upgrade for rifles already equipped with the MK2 Recoil Mitigation System, not a standalone replacement for a standard carbine or rifle buffer.

Why would I want a heavier T2 buffer? A heavier buffer adds dwell time to the cycling process, which can smooth out ejection and reliability on a rifle running excess gas, common on suppressed or short-barreled builds.

Does it work on suppressed rifles? Yes, it’s specifically useful for tuning reliability and ejection pattern on rifles running over-gassed conditions, which includes many suppressed setups.
