Most Helpful Positive Review AR10 spring
Had a cycling issue with an AR10 6.5 Creedmore build. I think it was cycling so fast the spent shell would not clear the chamber. This was the cheapest easiest thing to change and is rated for the AR10 carbine with 5.2 oz buffer for the AR10

Solid buffer for My 8.6 Blackout Pistol Build

by ReeceDOA, Verified Owner from GA, United States Written on March 10, 2026
Picked up the Sprinco AR10 Carbine Extra Power Red spring for my 8.6 Blackout pistol and couldn’t be happier. Cycling is noticeably smoother and more consistent compared to the stock spring, and it handles the heavier 8.6 loads without breaking a sweat.
Pros:
  • EASY INSTALL
Cons:
  • None
Best Used for:
  • 8.6 blackout
Would recommend: Yes

It’s longer

by Greg, from OH, United States Written on October 8, 2023
I haven’t actually shot the gun with this spring. I am hoping that it will help with my overgassed 16” 6.5 Creedmoor. It’s a couple of inches longer than the buffer spring I got from Areo Precision.
Pros:
  • Longer
Cons:
  • None
Best Used for:
  • Over gassed ar platform
Would recommend: Yes
