What should be expected from an Aero Precision, or other low end rifle regarding A2 sight alignment? I returned an AP AC15 mid because A2 sight misalignment. AP replaced the barrel in a fairly quick turn around, but the new barrel still took 10 clicks to sight in. I viewed a professional video review where it was stated that the rear sight had to be adjusted to the right on an AP rifle that was sent, knowing that a review would be done.
I think that the current barrel is no warranty issue, but I wonder how many low end rifles are delivered with a misaligned A2? It bothers me that the rear sight peep is so off center. Would it be worth a trip to a gunsmith, or would AP have trued it better if they could have? Thanks for your time and info. |

While I also get a little obsessive about having my guns assembled just perfect, and everything lining up just perfect, 10 clicks on the rear sight is not a big deal at all.
It also can happen with any gun/brand - if you rail, or your sight mount, or your barrel, etc. are just a few microns off, you will see a few clicks worth of difference at 100 yards. Tolerance stacking happens to the best of the best too. Cheers, S. |

If you really want it exact, you could always remove the pinned FSB and go to one of those clamp on FSBs.
Not as secure, for sure, but you could adjust it dead on for your rear sight, if it really matters to you. That's what National Match shooters do for competition shooting with competition grade iron sights. But, they don't have to use those rifles in combat or under stressful defensive situations. One hard blow to the side of such a FSB might move it. At best, it would throw your windage way off. At worst, it could misalign the gas port and cause a FTF condition. |

My DPMS NM set screw FSB was bumped 2 MOA when my cart fell off a 2500HD. I made sure the screws were snug and left it the hell alone, but noted my new zero was 2 MOA left of center and continued to shoot the same Master scores. |

Quoted:... It bothers me that the rear sight peep is so off center.... Why do you think they are adjustable? It is so you can adjust them for a zero because all rifles shoot a little bit different. If you want or think that a rear sight should be perfectly centered, you live in a fantasy world. Just zero it and learn to shoot it well. When you are looking through the sights, you can't tell they are off to one side anyway. If you can, you are not concentrating on shooting. |

OK, thanks for all the input. I will stop obsessing, and shoot the crap out of it!
I've never had a handgun that required a sight alignment (lucky I guess.) The rifles I zeroed in the military never needed more than 3 clicks adjustment. I've only owned 2 other rifles, and they were nearly dead on, as well. |
| When you plug the barrel into the upper, there is usually a wee bit of slop in the fit of the pin and upper slot. You can twist the barrel "taking out the slop from the appropriate side" to regain some of those unwanted clicks. I have known guys to take a few file strokes (a few NOT several) in that upper slot to bring the barrel and zero to an acceptable center. This is used in Extreem situations. |
