What is the center height of a reddot to the center of the barrel bore using a basic AR-15 Upper reciever, if the reddot is a 1/3 witness setup. I need it in inches.
I believe it's 2.55906" (65mm) for the irons. Add 0.275591" (7mm) for a 1/3 cowitness red dot = 2.83465" (72mm)
Rough estimate 2.6" + 0.3" = 2.9"
Different mounts/risers have different heights.
I forgot about that one. Are they still in business?
He never got into business. He was doing a kickstarter or some such. And got absolutely railed by arfcom. Pun was totally intentional.Quote:
