The Geissele Super 42 Braided Wire Buffer Spring and H2 Buffer Combo is a premium drop-in upgrade engineered to deliver smoother operation, reduced felt recoil, and increased reliability in .223/5.56 AR-15 carbine buffer systems. The Super 42 spring features Geissele's proprietary braided wire design that provides a flatter spring rate curve and significantly longer service life compared to standard music wire springs. Paired with a heavy H2 buffer (4.6 oz), this combo further reduces bolt velocity and minimizes carrier tilt for more consistent cycling, especially on mid-length, suppressed, and short-barreled rifles.

This complete kit is a direct replacement for factory carbine buffer systems and is a favorite among professional shooters and armorers seeking enhanced performance and durability.
