Curmudgeon's Review of Burris FastFire Reflex Red-Dot Sight Mounting Plates
I must own 10 of these bases for various pistols that I use the Fast Fire system on. 6 are Ruger Mark II, III, and now IV. The Ruger bases fit the curvature of the action perfectly and are easy to install once you remove the Ruger Rear Sight. NOW THAT CAN BE A CHALLENGE ON SOME GUNS!
The best thing about them is that the sight returns to zero after removing the sight to change batteries or do some other maintenance. I was pleasantly surprised the first time I did this. It returned to within 1/2" of the previous zero, making adjustment and re zero very easy. The worst was only 1.5" off. The \ trick I found that makes it easy is to put the sight and base in place loosely. Move it back and forth until the base finds its natural place, check to make sure the sight is centered over the action. Tighten with a torque wrench to the 12in-lb they specify. Zero and shoot away.
I have had these retain zero to within 1/2" for as much as 5 years or until the battery died (4+years)
