Yesterday I picked my first Bushmaster, second AR15. I trying to figure out what all the marks on the barrel mean.

The ones I know are:
5.56 NATO = chamber
1/9 = barrel twist
H BAR = Heavy Barrel.

The ones I Don't know:
B = Bushmaster???
MP = ????

MP always stands for magnetic particle tested. Barrel has been tested for defects.

Nice weapon.

B IS for bushmaster by the way. If it's like my pre-ban bushy it'll just eat up the federal 62 grain american eagle stuff , really good plinking ammo, but I wouldn't pick it for defense, it has a habit of punching neat little holes.
