Geissele AR-15 Carbine Buffer Tube Assembly Super 42 H2

This Geissele Premium Mil-Spec buffer tube assembly gives an AR-15 build a complete carbine recoil system in one box: a carbine length, mil-spec diameter tube with 6 stock positions, a mil-spec castle nut and end plate, an H2 buffer and the Geissele Super 42 spring.

The Super 42 uses a three strand wire design that damps spring vibration, cuts the familiar buffer spring twang and gives about 15 percent more average return force than a standard spring. The tube is machined aluminum and fits most mil-spec diameter AR-15 stocks.
