What gas system length? Carbine length or mid length? You are going to have one of the two since its a 16 inch barrel. Your buffer and spring will depend on that gas length. If its an AR pistol then you will be running a carbine length (unless they have a pistol length) and your buffer and spring should be for that length. My M4 mid length uses an H1 buffer. I think but not for sure carbine length uses H2 buffer so you better check. Best of luck with it.
