This kit includes all 21 of our current arbors so there are arbors for the 450 Bushmaster and the 7.62x39 included. The 45-70 is based on the 45 Colt cartridge so in order to bore sight 45-70 you would need the pistol bore sight kit, or you could use the AR45Colt arbor with the 30 Carbine laser bore sight (MBS30).

The Master 2 bore sight kit includes all of our existing bore sight arbors. Specifically the AR762 arbor will bore sight the 7.62x39 class cartridges, and the AR450BM will bore sight the Bushmaster chamber.

The only one that is an odd one is the 45-70. Because the cartridge is based on the 45 Colt, we use the pistol caliber laser/arbor from the 45 Colt to bore sight the 45-70.
