Anyone know a good conversion system that has a selective gas option for less and more, and also comes with a seperate carrier? I have a 16 inch Bushmaster I want to put it on. Thanks for any help
You should check out Adams Arms as well. I just went through a pistol/carbine and the instructor was carrying a colt ar with the Adams Arms piston conversion on it. The gun hadn't been cleaned in 2500 rounds (intentionally) and was still functioning flawlessly. After seeing the conversion in action, I am planning on putting the kit on my RRA.
