I bought the recoil buffer and it's a nice steel replacement for the old aluminum gas piston. Only the tolerances are so tight that it doesnt seem to work with the stock receiver button and recoil spring. Instead, the loose fit between the recoil spring and the button that releases the receiver cover causes the recoil spring guide to bind on the bottom of the inside of the gas piston. So if you are going to get the WE recoil buffer I highly suggest that you also improve the other parts by getting the ra-tech Dynamic Spring Kit. It's an abomination to the realism of the internals though, so I am going to try to file down the inside of the recoil buffer and see if it works.
