A couple uppers in the works.

16" 300 BO, pistol gas and 16" 7.62x39, carbine gas. Both are .750" and under freefloat handguards.


To operate suppressed, subsonic and supersonic, will I need adjustable gas blocks, and any recommendations, suggestions or things to avoid?


Much appreciation for anything useful to go from.


If I need to I'll make a cutout on the handguards to access the screw or whatever on the gas block. Is that a "thing" that's done? Might I need different/special buffers?
