Frequently Asked Questions

What does the ‘T0’ designation mean? It refers to a specific weight point in BCM’s MK2 buffer lineup; check BCM’s published buffer weight chart to compare it against other MK2 weights.

What does a buffer do? The buffer absorbs part of the bolt carrier’s rearward energy during cycling and helps drive it back into battery, and different weights can tune felt recoil and reliability.

Does this fit any AR-15 lower? It’s built to fit standard AR-15 buffer tubes; confirm your buffer tube type (mil-spec vs. commercial) with us before ordering if you’re unsure.
