Most Helpful Positive Review Reduced power for 300 AAC BO shooting
Had some issues with cycling on my 300 AAC BO pistol (7.5"), even when suppressed. Figured out it was being caused by short cycling, so got one of these reduced power springs to remedy that. Worked like a charm and now the gun cycles reliably. Definitely worth the upgrade.

best buffer spring out

by Gunguy, from RI, United States Written on February 11, 2025
I had the strike industries flatwire bufferspring thinking it was the latest and greatest but the strike industries was very loud everytime you pulled the charging handle back u hear that cheese grade sound and it was annoying i bought this and let me tell u this thing is VERY QUIET . Its like running a silent capture spring . Never knew a buffer spring could be this quiet and the coating on this makes it look really nice . This wil be the ONLY buffer prong i will ever use

Sprinco never disappoints.

by JeffH, Verified Owner from PA, United States Written on December 21, 2024
I run Sprinco in all 3 of my AR's. This particular one is used in a 7.62 pistol with a 10.5" barrel. It improved the cycling issues I was having with the standard spring. Recommended.
Pros:
  • High quality
Cons:
  • None
Best Used for:
  • 7.62 x 39 pistol (In my case).

great spring especially used in combination with kynshot

by hunterhos, Verified Owner from FL, United States Written on December 9, 2024
Really like these Springs to use in combination with the hydraulic kynshot buffer. Plus the very affordable so you can buy some of the different powers to get the right combination

Spring go boing

by Ron, Verified Owner from UT, United States Written on June 12, 2024
It's a spring that compresses when you push on it, and then expands when the pressure is released. If you listen closely, you can even hear a boing sound.
Would recommend: Yes
