Geissele Super 42 H3 Buffer, Braided Wire Spring, Carbine Length for AR-15

Geissele Super 42 H3 Buffer Spring for AR-15.\n\nThe Geissele Super 42 Spring is designed to improve the function and reliability of AR-15 pattern rifles. Its braided wire spring design uses three independent strands of wire, acting as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This design helps displace excess energy which decreases the chance of spring failure and helps make your AR-15 more reliable. Compared to the stock spring, the Super 42 Spring has a reduced tendency to lose length and force over a given round count. It also reduces spring reverberations (twang) heard and felt by the shooter through the buttstock. The Super 42 Spring has a ~15% stronger average return force than the standard buffer spring, which can aid in stripping rounds from the magazine when operating with a dirty weapon or steel-case ammo.\n\nNote: The Super 42 is for use with Carbine-length buffer tubes and is not compatible with rifle-length or A5 buffer tubes/receiver extensions.\n\nProduct Specifications:\n- Series: H3\n- Model: Super 42\n- Firearm Fit: AR-15\n- Material: Braided Wire\n- Size: Carbine
