So if you have a 16" barrel and a carbine gas system, what buffer would you run?
A lot depends on the size of gas port they drilled but I run an H2 on my Colt carbine. An H3 might be better but only the gun can tell you for sure.
That's the problem with "hobby" guns (for lack of a better word) they have to port em large enough to run the weakest 223 ammo out there. When you switch to 5.56 full pressure loads, the things are way over gassed.
And no buffer is gonna keep you on target without running a brake.
