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.

Reduced spring power

by Clay, Verified Owner from LA, United States Written on June 11, 2026
Works well. Using on a 6in 300 blk barreled pistol . The faxon 6in has very little dwell time to build any pressure so this spring helped with short stroking .

fixes any issue

by Robert Twombly, Verified Owner from KS, United States Written on May 2, 2026
I bought various Sprinco buffer springs for my AR’s. With the right buffer spring and buffer weight you can fix any under or over gassing issue your AR has. I’ve used the yellow version for under gassed and the red version with the Odin Works adjustable buffer weight with my Partisan FRT trigger and that made it run like butter. The orange version works well in AR 10’s. I recommend buying every variant to have in stock for any issue you run into.

impressed with the outcome

by Daniel, Verified Owner from SC, United States Written on April 21, 2026
It’s a great upgrade over stock. Especially suppressed with h2 weight 4.8 with adjustable gas block. On 5.56 16” barrel mid length . Would purchase again
Pros:
  • Better than a cheapo unit
Cons:
  • None

Sprinco Power Spring - GREAT BUY

by Ray S, Verified Owner from MI, United States Written on April 14, 2026
Needing something a little better for my big bore AR-15 (.350 Legend and .450 Bushmaster). Made the recoil really controlled with an H3 Buffer. Planning to buy another one for a second lower.
