The kit works as intended, however it does require a good amount of careful shell-cutting and fitting for it to work correctly. It is not as simple as cutting a few tabs and dropping it in. You'll want to pay careful attention to where cuts are made to ensure that the bolt and barrel remain perfectly in-line with each other and that the bolt can be pushed all the way forward into the barrel to ensure a sealed fit. It does work though, and is a solid, secure fit when positioned correctly. Note that Instructions for cutting found online are not perfectly correct, but close enough to get you started.
