I have a question for the masses out there. I have an old A1 CAR15 with an 11.5 inch barrel and a 5inch flash hider. I have a Bushnell Holosight mounted on the rail so it co-witnesses with the irons. I also have a Tacbeam laser that is mounted on the side of the rail to my left. My question is at what range would you set the laser to co witness with the Holosight and the irons. I’m a citizen at this point and all I do is some close quarters drills and compete in three gun shoots. My experience goes back to when this weapon was made. So I predate both red dots and lasers. Guess I need o be drug into the 21st. :shoothea:
