carbine length buffer

A carbine length buffer is a recoil management component designed for AR-15 rifles with collapsible (carbine-style) stocks. It fits inside a carbine-length buffer tube and works with the buffer spring to absorb recoil and ensure reliable cycling of the action. The carbine length buffer is compatible with AR-15 lower receivers, carbine length buffer tubes, buffer springs, collapsible stocks, upper receivers, and bolt carrier groups. It’s essential for smooth operation and consistent performance in AR-15 builds using carbine-length buffer systems.
