ReeceDOA's Review of Sprinco USA SPRINCO AR10 Carbine Buffer Spring

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
