After the ban expires I want to change my plain post ban Bushy A-3 20in into an A4gery. What parts do I need exactly. I know the handgaurds are diffrent what kind are on the A4? I also would want the evil FS installed and bayo lug(just because I can)is it the standard A2 birdcage flashhider on the a4's?. Would the barrel need to be turned down? If so what profile or size would it need to be. Who would be the best people to perform this work?
