Re: What Distance Should you Zero your AR 15?

It has been my habit for a long time now to zero my iron sights and RDS optics at 50 yards, and magnified optics for whatever the optic manufacturer recommends, for the caliber of the rifle. For example, the Primary Arms 1-6x24 FFP SLX scope with their ACSS Raptor reticle recommends a100 yard zero for .223/5.56x45, and a 50 yard zero for .308/7.62x51.

A while back, I removed the ACOG and reinstalled the carry-handle rear sight on my A4 clone, and then tried the USMC armorer's modification to the rear sight drum (info here) that adds click values for 50 and 100 yards and allows a 50 yard zero. I have zeroed it at 50 yards, but haven’t yet confirmed the bullet rise/drop at one, two, three, four, five, and six hundred.
