Zeroing in

[romegg]

I just purchased a new Bushmaster XM15E2S-A1. This model has no elevation dial,and this is my first AR. Can anyone explain to me how to zero it in. Thanks

Normal BZO is done at 25m. You use the front sight elevation to hit POA=POI at 25m. This will allow you to hit torso size targets out to 300m. (if you do your part) The draw back to this is you will hit high everywhere in between.

You could also shoot it at any range and adjust the front sight post elevation to hit POA=POI. This would give you your zero at that range.

simple:
front sight is elevation. rear sight is windage.

Start by shooting in on paper close to see where you even are, then work out from there. I would strongly suggest a 50m/50y zero over the 25...

+1 on the 50yd zero option. I used the Improved Battlesight Zero by CHuck Santose. Doesn't exactly work by the numbers on an A1 sight but a 50 yard zero will give you a pretty flat POA out to 200 yards or so.

Here's a diagram that Kevin Boland from Knight's Armament posted on another forum.

This is the one I've been using as well. 50yd poa/poi.
