Super nice product well made.
USDirty bird optimized buffer kit
I bought this for my M&P15 to replace the stock buffer and spring. I’ve shot 200 rounds since. The cycling right off the bat is a lot smoother and the recoil is considerably less than before. The H2 buffer and heavier spring is a perfect combo
