Tws peep sight - Texas Weapon Systems Gen-3 Basic Rear Peep Sight for Gen-3 Top Cover

Small and lightweight addition to a railed dust cover. Would be better if redesigned with a square recoil lug and a little tighter fit on the rail's dovetail shape, but mine is on solid, so i cant complain too much. Also peep is somewhat coarse, wouldnt hurt to have a slightly smaller diameter peep, can fix that with some testors flat black model car paint. Use blue loctite on screw.
