    I currently have a set of magpul flip up sights on my AR and am looking for tips on getting the rifle "zeroed in". I found this video which I think will be helpful. http://www.youtube.com/watch?v=j5QCGWYfHWk
    If anyone has any tips or tricks with zeroing in a rifle with magpul sights I'd appreciate your help.
    :cool:

    No real trick to it. Go the the 25 yard range and get it centered on paper but don't need to be perfect. Then go to the 50 or 100 yard range and zero there. I prefer three round groups for zeroing.

    Nothing special, just decide which zero you want, I prefer a 50yd/200m, then go to the closer of the two distances, shoot 5-10rd groups, adjust the sights as needed, and repeat until zeroed. Then, if you can, check the zero at the longer distance and make any necessary adjustments.

    For AR irons, you adjust the front sight post for elevation, and the rear aperature for windage.

    Just don't over torque the screw on the sights or you'll be sending them back to Magpul like I had to.

    Over tightening a steel crew on a polymer part, use your imagination.

    Put gun on a bench/sandbags, set up target at 25y. Shoot a few rounds(3), check, adjust, repeat. Move target further away repeat again. When you get to your final distance, shoot a couple of 5-10rd groups. I happen to also like the "50/200y" zero. It ends up being more like 220y in my gun/ammo combo. Either way, bullet path is only about 2" off from zero to about 250y.

    As Captains1911 mentions above it is a 50 yard / 200 meter zero which is why your combo is almost 220 yards as 200 meters is almost 219 yards. :)

    Pretty much it will crack the groove that goes over the rail. On mine the crack wasn't very bad but even that much tilted the sight about 10 degrees.

    I have to say that the CS at Magpul was great. I sent them an email just describing what happened and I got a reply back in less than an hour. I sent the sight back to them and just waiting for it to be shipped back. They said the newer Magpul sights have a bar in them to prevent over tightening.
