Excellent Mount by VirtualMayhem, Verified Owner, May 19, 2016
Purchased this 45 degree mount for an AR10 build. Quality construction - very well built and is being used for a backup red dot. Mounts to the rail well and it's not loose. I highly recommend this mount!

Solid mount by Matty, September 21, 2022
