Fixes any issue - Sprinco USA Sprinco Power Buffer Spring, AR15 Carbine

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.
