I finally got around to putting this rifle together. I am not quite sure what is going on, but at 50 yards it shoots fair. I strung 6 shots in 2 inches which would make me think it is a trigger pull issue. At 100 yards, I am at about an 18" group. I have pulled off the brake, pulled the handguard, retorqued the barrel nut 4 times. I havent pulled the gas block yet. I shot the two boxes of ammo I had on hand, no one here in Trinidad sells it, so i in have to order more. I think I may drop it off at the gunsmith tonight to see of he has any other ideas.
