The Geissele Super 42 Buffer Spring/Buffer Combo 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 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 AR-15 more reliable.
Compared to the stock spring, The Geissele Super 42 Spring has a
decreased tendency to lose length and force over a given round count. As
an added bonus, it removes the annoying 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. This will assist in stripping rounds out of the magazine when
operating with a dirty weapon or when using steel-case ammo. Not
Compatible with Rifle Length or A5 Buffer Tubes/Receiver Extensions.
