Description The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the spring to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable.

Recoil Technologies AR-15 9mm 5.5oz Carbine Buffer This 9mm buffer is designed to be used on new or converted AR-15 shooting 9mm. Depending on a number of factors including barrel length, a heavier buffer may work much better than the standard 3 oz buffer. It is also used to reduce cycle rate of the AR-15 and felt recoil. This is a 5.5 ounce filled buffer to facilitate correct timing, cycling and firing of 9 mm and 9 mm +P loaded ammunition.
