A few years ago I bought an at lower just to have. I just purchased an upper with forward assist from midway and have plans to buy a bolt carrier group and charging handle from PSA. My main question revolves around the barrel. I think that I want a 16 or 18 inch stainless barrel with a 7 or 8 twist with wild or 556 chamber that I can blast with and punch paper,targets, a d animals when pa legalizes semi autos. I'm thinking that a profile similar to a colt 6920 would be about right.

My barrel budget is about 300 bucks and idont need a bolt. I see a few white oak armament barrels for 250. How are they? What other brands are good? My neighbor who was an army armorer is going to help with assembly.
