The Geissele Super 42 braided wire buffer spring is a concept that is similar to a spring that was used in the German MG4 machine gun. The unique spring design utilizes three independent strands of wire which helps to act as a harmonic damper and energy absorber. The springs can flex separately from each other which allows you to displace excess energy which decreases the overall chance of having a spring failure. The result of installing this kit will be improved function along with enhanced reliability with your AR-15 platform rifle. Additionally the Super 42 features a 15% stronger average return force than the standard buffer spring and as such the use of .300 AAC Blackout Subsonic loads is not recommended.

Could I use this buffer an spring in a 340 legend ar 15?
Answer:
This spring will work with 350 Legend AR15s. Buffer weight recommendations are dependent on barrel length and gas system length. If you barrel is less than 12" long, then this H3 buffer is a good option. If your barrel is 12-16" with carbine or mid-length gas system the manufacturer recommends the H1 or H2 buffer. If your barrel is 18" or longer with a mid-length or rifle length gas system, the manufacturer recommends the H1 buffer. Check out item # 2-GEI05-495 and 2-GEI05-495-H2.
