Geissele Super 42 AR-15 Carbine Braided Spring and H3 Buffer

The Geissele Super 42 combo pairs a braided wire buffer spring with an H3 buffer for carbine length AR-15 buffer tubes. The spring uses three independent strands of wire, the same idea as the German MG42, so the strands flex separately and soak up energy that would otherwise wear out a spring.

It holds its length and force longer than a stock spring, kills the twang you hear through the stock, and has about 15% more return force to strip rounds from the magazine when the rifle is dirty or running steel case ammo. It does not fit rifle length or A5 buffer tubes.
