| I have an Ar-50 which has a 15 moa rail on it and I just purchased a LT107 mount with 30 moa built in. I have a swfa 16x fixed scope and will be shooting hopefully out to 600-800 yards soon but will zero it at 100 yards for now. Will this be to much built in moa adjustment or should I be fine? |

You could be in trouble.
I looked on the SWFA website and didn't see the total elevation adjustment listed. I think some Nightforce scopes have 110 MOA total adjustment, and some of the Vortex scopes have 65 MOA. With the Nightforce you'd have 55 MOA of downward adjustment to compensate for the 45 MOA built into your mounts, assuming it would zero at 100 while the scope was centered. With the Vortex, you'd only have 32.5 MOA of downward adjustment, leaving a 12.5 MOA hold under for a 100 yd zero. |

Because I got the mount for free and it is really nice. 
Try and trade it. |

I emailed SWFA and they replied that the scope should have 30 mils of vertical adjustment. according to google a mil = 3.4377 moa totaling 103.13 moa. I should be okay with this setup then, sorry i am new to all this and trying to get it sorted out. Thanks |

Thanks Still cutting it pretty close for a 100yd zero. That ~100 MOA may be evenly split at +50 and -50, it may not. You're taking up 45 of that with the mounts. Between that, tolerances, and height over bore, your 100yd zero is going to be within a few MOA of maxing out your vertical adjustment, which will amplify any scope cant or tracking errors the further out you get. |
