And plan on usings a limited selection of well-tested and adjusted ammo. The M1 Garand runs a gas-port that's 1/2" from the muzzle of that long rifle barrel, and it works well. But it runs a pretty big gas-port, and has a limited window of ammo that works right.
Yes this will only be feed handloads.
As I stated a adjustable gas block will be used, as well as a lowmass bcg and buffer system.
16 inch with rifle gas isn't unheard of, lots of 16 inch 556 barrels out there like this. But to best of my knowledge noone has done it with a grendel. Yet lol.
Probably only running 120 gold dots.
Anybody on here have any technical data from a 556 barrel like this? Are first hand knowledge of a 556 barrel like this to help me figure out what port size I might need too use?
