Sorry I was out of town. Yes the RSTA will work on a 17s. The shims will work also but it is a real pain to deal with. If I was doing it I would get the flash hider and not the brake just to save the trouble. As far as the 13" barrel is concerned then you need to make sure that you have about 4" of barrel. One of the benefits of this silencer is less blowback and backpressure and it allows you to run a longer silencer without adding more to the end of the barrel.
