RECOIL SYSTEM SUPER 42 H3 HK416 MR556 GEISSELE 🇺🇸

The Geissele Super 42 Spring has approximately 15% more return force than the standard carbine buffer spring which is comparable to the factory HK416 recoil spring making it a viable drop in option for HK416 and MR556 rifles.

This system was designed to improve function and reliability, its unique spring design uses three independent strands of wire, a design made famous by the German MG42 Machine Gun. The three springs act independently to absorb energy by allowing the springs to flex separately, this flex helps displace excess energy which decreases the chance of spring failure. As an added bonus, it removes the annoying spring reverberations (twang) heard and felt by the shooter through the buttstock.

Included:

• Geissele Super 42 braided wire recoil spring
• Geissele H3 Recoil buffer

Weight – 5.4oz (The correct weight for use with HK416 and MR556 rifles)

Weight System – Three tungsten weights

Made In USA

NOTE:  The Super 42 is for use with Carbine length buffer tubes and is not compatible with rifle length or A5 buffer tubes/receiver extensions. The Super 42 is not recommended with 300 Blackout subsonic ammunition, the spring may be too powerful and not allow the rifle to function properly. The Super 42 spring and Geissele buffer are designed to work together as a set (the spring will not fit over a standard buffer). If installed with a standard buffer damage to the rifle or receiver extension will occur.
