Geissele Super 42 Rifle Length Spring

The Geissele Super 42 Rifle Length Spring for the M16 or AR15 gives you the performance and user experience improvement of the Super 42 spring for your rifle length buffer tube. This unique spring design uses three strands of wire. This acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your M16 or AR15 rifle more reliable while diminishing the “twang” sound from the butt stock. The Geissele Super 42 Rifle Length Spring works with a standard rifle length buffer and buffer tube.

NOTE: The Super 42 Rifle Length Spring is compatible with a mil-spec rifle length buffer.

NOTE: Not compatible with a carbine length buffer tube. If you have a carbine length buffer please see the Super 42 Braidied Wire Buffer Spring and Buffer Combo instead.
