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.
Nice buffer
Works great in a phase 5 rifle length hex tube. definitely quieter that a standard spring. Cycles 11.5-17" 5.56 and 8" 300 blk subs and supers perfectly. Makes a great "do all lower" buffer system.
Pros:
- Quiet
Cons:
- Expensive
Best Used for:
- Rifle length ar buffer tube
Would recommend: Yes
Best spring by far
Put in an AR that runs hard and literally kills springs, after replacing the buffer spring a few times and having same result of working perfectly first time out shooting then all the sudden running super slow as the spring is dying. Decided to try the Geissele and went the extra mile of converting the buffer to rifle length with a BCM Mod 2 buffer tube and BCM T series buffer. Now it’s flawless have not had any problems since. If you are running a binary, FRT trigger or especially FA this spring is a must have. I actually purchased a back up Super 42 rifle length spring just in case but don’t think at this point I will ever need to use it. Geissele builds their parts like a tank. Could not be any happier!
Pros:
- Best in the business
Cons:
- None
Best Used for:
- High performance triggers
Would recommend: Yes
Ruger SFAR
This product will work in a Ruger SFAR buffer tube. Must be Rifle length spring. Ruger SFAR uses a carbine buffer weight and proprietary buffer spring. You can use this spring for SFAR to slow down the bolt cycle. I used it to cure over gassing issue.
Pros:
- None
Cons:
- None
Would recommend: Yes
Made M16A4 Build Under-gassed
I put this in a 20inch Aero Precision M16A4 build with a fixed front gas block and a fixed rifle stock. I installed the buffer spring and kept the stock rifle buffer. When I took it to the range to zero, the rifle was very under-gassed. The rifle would extract the fired round but did not have enough gas to put another round in the chamber. The bolt went forward each time and would not lock back on last round. After every round (around 100 all together ), I would have to drop the mag, manually lock the bolt back, insert the mag and hit the release to chamber a new round. Needless to say, I went home and put the original buffer spring back in.
Would recommend: No

SFAR recoil needs "tuning"
Needed to tune the recoil on my SFAR. This spring and new H1 buffer did just that. Caught everything on sale. Very happy with the results.
Pros:
- Price and Craftsmanship
Cons:
- USPS snail mail delivery
Would recommend: Yes

geissle makes the best springs
While springco is great, Geissele buffer springs just come out on top (unless you need something very specifically tuned). Silent and consistent, not much else to ask for.

Great spring!
Though this spring is significantly more expensive than standard rifle length springs, it is worth it. I have my own line of ARs that I build for my business specifically to my specifications and this is the spring I use. It is very consistent, smooth, and reduces spring noise dramatically. Additionally, the price through opticsplanet is almost the same as dealer cost through RSR. The only difference is, opticsplanet always has them stocked and RSR is very hit or miss on stocked inventory. If you haven't tried the Super 42 series of springs yet, I highly recommend them!
Pros:
- smooth operation
- Consistent Longterm Performance
- Spring Noise Reduction
Cons:
- None
Would recommend: Yes

Geiselle super 42 rifle recoil spring
These springs are essential, so smooth and eliminate that twang you generally get from the ar platform. I run these in every rifle I have. Well worth it.
