Rb5000 - performs as advertised - KynSHOT AR-15 .223/5.56mm Carbines Recoil Buffer w/Collapsible Stock

Easy drop in replacement for the stock buffer in my M&P 15 Sport III. A little different feel pulling charging handle back the first time. My bolt did not seem to go back enough. However, that last bit of pull needs to compress the hydraulic part of buffer. Once I figured that out, the bolt locked back when needed with charging handle. Wasn’t sure if the last round in magazine would lock bolt back. Took it to the range and fired about 100 rounds no problem. I definitely feel a slightly reduced recoil.
