So... I'm new and panicking. I bought a new Bushy flat top XM-15 at a local gunshow (after selling everything I own and saving pennies for months  ) and couldn't be happier (no Bushybashing please). However, when I went to the range to zero her, I realized that the front B.M.A.S. flip-up sight is canted ever so slightly to the left, and to compensate, I have to crank the rear sight almost all the way to the left. The cant is just barely visible to the naked eye, but I'm a bit OCD. At 25 yards I managed to pull off consistent 4 MOA 5 round groups. My question is this: Will the canted sight effect accuracy at longer ranges? Will it effect the fuction of my rifle or is it just visual? I'd really like to avoid sending my entire upper reciever away to Bushmaster for three weeks. Any help would be awesome, and any remedy to fix the sight would be even better.

I would send it back and have them fix it.
It's just going to bug you, and they need to hear about these issues from the end-user community in order to address them from a QC standpoint. If the turnaround is only three weeks you can live without it for that long without climbing the walls. Besides, you said you don't have money for range trips any time soon anyway. My Bushmaster is one of my favorite ARs. |

Quoted: 8 clicks of windage either direction is well within the acceptance standard for the military of up tp 12 clicks. Maybe that's cool for the .mil, but I'd send it back to Bushmaster. I had the exact same problem with a 20" Bushmaster upper a while back. Sent it back, and two weeks later, it came back with a test target and perfectly centered rear sight. Now it's dead on and I have plenty of adjustment, both ways. |

I just checked a rifle and I got 38 clicks to one side, so that means he needed about 30 clicks to zero. |
