Also,a little trick I learned in the Marines when shooting open-sights is to put a 2" or so piece of tape over the place where the upper closes down and mates with the buttstock.This will help keep the gas fumes from screwing with your eye!!Originally posted by arrowbullet
If I have one word of advice, make sure that you're getting your eye close to the iron sites. The .223's are designed to be close, and if you're not, your groups are going to suck. I figured this out the hard way.
