Do you have problems with the eye relief and not being able to mount the sight far enough back?
I've got a Burris AR-536 but I had to stick my nose close to the rear sight and pull my should back to make it work. Not comfortable at all.
Do you have problems with the eye relief and not being able to mount the sight far enough back?If all you want is 4x magnification then I recommend the Primary arms 4x or 5x prism optic. Those things just work. Then buy a bradly cheek rest you are going to need it. If the price/quality is too low for you then go vortex, leupold, bushnell...
But for the price these things just perform and are a great straight forward battle sight.
