1:16 twist on that barrel. Dedicated CMMG barrel with their chamber adapter for their 22 conversion kit that normally gets used in a .223 barrel. I think CMMG might have used to sell a pistol version of a 22LR AR and thats what these parts are meant for although I dont see them list it any more.
99-114% of what I shoot is cans so this one makes sense. Ive got dedicated 22LR ,9mm,.223 and 300 BO SBR's now.
Awesome. Thank you... I’m trying to figure out what length handguard would work best. Right now I have a 7” but if I can get away with a longer one I will. My Spectre II will be in jail for at least 6mo.
