Great Red & Green Dot for the money by Joe, Verified Owner, January 1, 2016
Great quality at a reasonable price. The cantilever mount is the perfect height for co-witness with the iron sights on my AR. Controls are conveniently located and easy to manipulate even gloves. Anti-glare coating works well. Only complaint is I wis...

Good quality for the buck by Steve, November 17, 2015
I got this just in time for deer season and put it on a rifle that I was having trouble holding a red dot on. This held up well and I got a 8 point buck with it the first day. I like this red dot very much but not for my deer hunting. I miss a scope ...

Great budget piece by Loren Strait, Verified Owner, October 19, 2025
Mounted with a 3x magnifier. The 30mm tube gives decent field of view and the emitter sits tucked up out of the way where it’s not a distraction. Cantilever mount is included and looks sharp. Can’t speak to its durability yet. I’ve had a couple cheap...
