    Per the instructions from CA, the Barrel nut gets torqued to 30 ft/lbs, loosened, then torqued to 45 ft/lbs. It is loosened again and then torqued to 60ft/lbs. The hand guard screws are torqued as follows: Front screw - 25 in/lbs and rear screw - 20 in/lbs. I hope this helps.

    The Colt CCU upper I got shot very accurately once I got the Aimpoint T1 zeroed. I use DD back up sights set up at the ends. I couldn't zero it at 25 yards (POI is 2 inches to the left) even with the rear sight adjusted all the way to the left. I suppose it is easy to loosen up the screws and rotate the rail a little bit to the left and resecure the screws. but mine has 3 hand guard screws, 2 that uses a larger Hex wrench than the 1on the other side. what should the torque be on the middle one?
