Men, i just purchased this colt 6920 socom ar15. Topped it with a trijicon acog. I had to remove the buis on the rail, to get proper eye relief. Is it just me or is this common? So much for having back up iron sights. I moved the scope back as far as i could with that buis on just didnt feel comfortable. Another problem i encountered was the front sight is in my sight picture with my scope in all positions. It is annoying, is there a way to remove it? Is there something i should replace it with? I love my colt, just looking for some good ole sniper hide advise. Thanks and god bless
