Most Helpful Positive Review Silence is golden
Purchased this to go in my 18" "SPR" type build I put together several years ago. Rifle has a plane jane A2 stock/rifle length tube setup, rifle lenght gas. Rifle has been a sweet shooter since day one...dead-nuts reliable and soft shooting. Only thing that sucked was that A2 twang. Decided to give this a try with some OpticsPlanet bucks I had. Surprised to say it all but eliminated any sound from the stock.

Geissele Buffer Spring

by Grimey556, Verified Owner from IN, United States Written on September 3, 2026
What can I say it's one of the best springs on the market. Works really well with the A5 system whether it be 556 or your AR47 in 7.62. The thing I like the most about these Springs is how quiet they are when you are running suppressed. They don't make the boing noise like most springs do.

super 42 spring

by jo, Verified Owner from NC, United States Written on August 28, 2026
The Super 42 rifle spring made a noticeable difference in my rifle’s ejection. Before installing it, my ejection pattern was inconsistent, but after the upgrade, the rifle ejects much more consistently and reliably. It’s a simple upgrade that noticeably improved the overall cycling and function of my setup. Definitely worth it if you’re looking to improve ejection consistency.

Super 42 Difference

by Vince, from UT, United States Written on August 23, 2026
The Geissele Super 42 made a tremendous difference in the recoil of the rifle. It no longer feels and sounds like a toy. I feel that it also made feeding rounds a lot smoother.

Geissele Super 42 Rifle Length Spring

by Ronin48, Verified Owner from NC, United States Written on June 16, 2026
Well, I don't have a MG42 machine gun but I know that's what inspired Geissele to make this buffer spring. It's definitely has that extra push and I feel it probably will never take a set or wear out....I can't afford the amount of ammo that would probably take. I started with Geissele by buying their excellent triggers and I have to say, I'm most impressed with them and I thought the same quality I'm sure goes into all of their products. I'm very pleased with this spring.
Pros:
  • All AR rifle builds
Cons:
  • None that I can find....
Best Used for:
  • AR rifle builds, professional/tactical use.
Would recommend: Yes

Cons:
  • Only works with Geissele
