Take a close look in the muzzle end with magnification and light. You may be able to see things which are just not right.
If there is noticeable scoring BCA should take it back. I sent two barrels back and they sent me 1 MOA ones.
Before barrel. 7.62x39

After barrel. 7.62x39 This one shoots MOA with steel jacketed Tula ammo so it is GTG even with the minor gouges.
