Need a flip up sight sight on this gun since I bought a scope. This Larue BUIS is in BRAND NEW condition. I bought it, put it on a gun that does not get out much. Literally like 2-3 range days is all it saw. Perfect shape. These are $121 plus shipping NEW with same plane sight. Will sell for $100 shipped or trade for like new flip up sight of equal quality/value.
