Geissele Automatics Super 42 Carbine Length Buffer Spring & Buffer Combo, H1
The Geissele Super 42 Spring 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.
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, a special rifle length version of our Super-42 is available on our website. We do not recommend the Super 42 with 300 Blackout subsonic ammunition. The Super 42 Spring may be too powerful and not allow the rifle to function properly.

HUGE improvement over my milspec buffer and spring. Took the “twang” out of each shot. Recoil seems a little bit better too. As for shipping, product came in two days, nicely packaged, with a free sticker and some Ramen! Not to mention the best price I’ve seen all year. I’ll be recommending Sol to all of my friends!

Excellent product. This buffer spring helped to reduce the twang in my AR15 and was very nicely packaged. Rooftop shipped quickly and had the best price. Package came with some ramen and a personalized note. Doesn’t get any better! Buy with confidence.

Works as it should, and my rifle fires even better now. Rooftop defense was great at shipping the item in a timely manner and adding in the ramen and hand held constitution made me a life time customer

Works great. If your rifle feels “clunky” when shooting this helps smooth things out. Does make perceived recoil feel a little lower however it can give a budget lower a much nicer feel at a good price.
