I have an AR-15 (Armalite 14.5 inch upper) that is throwing the cases at 2:00 to 2:30 about 5 feet away. The rifle is clean and oiled and the ammo is Federal 55 grain American Eagle. The butt stock is a full rifle style with a rifle buffer and spring (new and the proper length).
According to the experts a properly gassed rifle should throw the cases between 3 and 4 o'clock for optimum operation. My set up seems to be very reliable as is and fires and ejects the way it's supposed to. I'm not away of any harsh increased recoil.
My question is - Are most carbine length short barreled rifles slightly over gassed from the factory and is this an issue that I should be worried about as far as accelerate parts wear is concerned?
