View Full Version : AR-15 Front Sight -- How to adjust windage

04-15-2009, 10:36 AM
I have a Bushmaster HBAR carbine upper with the standard front sight, which has 4 holes for elevation adjustments. But how can I adjust the windage on the front sight? I need to move it left!

Windage is typically found on the rear sight.

You can't adjust windage on the front sight, only on the rear. If you find that you have to make an excessive number of clicks in order to zero, you may have a canted front sight or another issue which needs to be checked out.

yes, perhaps it is canted, I have to do 10-15 clicks to the right from zero to get in the black at 100 yards

White Oak Precision Service Rifles have windage adjustable front sights, those are the only ones I know of.

Windage adjustable A2 front sight bases aren't just on White Oak barrels. RRA, CLE, Bushmaster, Armalite, and other manufacturers will typically put such windage adjustable front sight bases on their "National Match" rifles.

It's nothing special. It's simply a modification where the barrel has flats drilled into it so set screws in the FSB will position the base.
