Most Popular Buffer for AR-15 / AR-10 / AR-9 Builds in 2026
The top 15 most-used buffer in 2026, ranked by how often they appear in builds tracked on AR15.Build. Updated nightly.
The buffer's weight directly affects how fast your bolt cycles — too light and you get failures to feed, too heavy and the bolt may not fully cycle. Heavier buffers are commonly used with shorter gas systems and suppressed builds to slow bolt velocity and reduce wear.
