Battle Arms AR-15 Carbine Buffer System - Enhanced Performance & Durability

The Battle Arms Development AR-15 carbine buffer system delivers mil-spec reliability for builders and shooters who need a straightforward replacement or upgrade. Whether you're assembling a new rifle from the ground up or swapping out a worn buffer on an existing build, this H3-weight unit drops straight into any collapsible AR-15 or M16 buffer tube without modification. At 5.4 ounces, it's engineered to handle the cycling demands of intermediate cartridges and maintain consistent performance across a wide range of shooting conditions.

Battle Arms Development builds these buffers to outlast typical mil-spec components, so you're not replacing them every few thousand rounds. The straightforward design means no surprises during installation—it works with standard collapsible stocks and requires no special tools or gunsmithing. Reliability and durability matter when you're counting on your carbine, whether that's on the range, in the field, or for defensive carry.

If you're running an AR-15 or M16 and notice sluggish cycling, failure to return to battery, or just want fresh mil-spec internals, this buffer pairs with your existing tube and spring setup. The H3 weight is a proven middle ground for most shooters: heavier than standard to smooth out recoil impulse without over-dampening the action.
