There are 2 types of 264 LBC-AR reamers. One has a neck of .295 and the other has a neck of .300. The tight chamber is for bolt guns and high performance AR, does not like some factory ammo. The .300 neck is for AR will shoot all factory ammo.
To determine what you have, shoot some ammo and measure the brass at the neck, it will be either .295 or .300.
