SBR a Calvary Arms plastic lower/buttstock?
Has anyone ever SBR'd a Calvary Arms plastic lower/buttstock?
I bagged one of the Noveske 10.5" .300 Fireball barrels a week ago. I thought about doing a Form 1 for an SBR on the plastic lower and another Form 1 on a titanium 9mm suppressor for it.
My concern is engraving the plastic lower, any challenges with that?
Does NFA require it to be metal?
Any thoughts please.
