by Alex O., Gear Expert, November 9, 2021
I have a scope on top of my AR and was looking for something to mount on at 45⁰ to rotate for closer engagement. Can this,? any suggestions? Expert Answer

The SIG SAUER ROMEO5 1x20mm Red Dot Sight could be used as a 45 degree offset optic with the correct mount. However, I would recommend using a smaller and lighter optic such as the Swampfox Liberty 1x22mm RMR Dot Sight (linked below) paired with the Strike Industries Strike Ambush 45-Degree Optic Mount, also found by using the second link below:

Helpful Positive Review Rugged and handy by LER Bob, Verified Owner, December 11, 2024
It has been surviving under a heavy barrage of full power 12 gauge loads in a light shotgun. It turns off when unused and turns on when the gun is raised. Rain hasn't been an issue while hunting. I lost the bikini cover but use a small neoprene cover...
