Sighting In
 
Hello

Has anyone else had trouble sighting in a Bushmaster M4A3 using a GG&G BUIS. I'm printing almost 8" high at 100 yards and I've run out of adjustment for my front sight. If I go with a taller front sight post it will stick out past the "ears" and could snag on stuff.

I'm not familiar with your rifle, but I suspect the front and rear buis sights are either not compatible, or you have a carry handle A2 rear sight and the front buis sight is not standard height. If you have a removeable carry handle you can buy a rear sight to match the front sight. If your rifle is a flat top you need to buy matched front a rear sights, like the Mangonel flip-up. They are NOT cheap!
