Contributing member by Wacman, April 5, 2016
i used this scope mount on my AR-15 and could not be happier. i pared it with a Nikon 1.5x6x32 orange dot scope, and it is spot on for performance. i use this regularly in competitions and it has stayed stable the entire time.

Nikon M mount by tbaugh, Verified Owner, April 6, 2016
Nice mount holds "0" well. The only thing I didn't like is you have to remove back up sights and slide it over the rail to install. I like to be able to switch from a scope to a red dot. this mount is made to be installed and left on the rifle.
