I hear it's all the rage to shoot pistol rounds out of a 16"+ barrel... would love to see what folks have bought or built.
I'll go first, the photo is of my recently built 45 ACP left-hand DI AR carbine. How's that for a unicorn gun!
I haven't done formal accuracy testing, but with good ammo seems to be a tackdriver at 25 yards and no slouch at 50 yards.
Looking forward to doing some reloading to see what it will do with some juiced 45 ACP rounds.
