This is the Ruger 22/45 Lite. As you can see, it is sporting Advantage Tactical Sights. It just so happens that when the factory sights are removed, our shotgun base fits neatly over the frame and barrel, just enough to obscure the factory sight cuts. We then drilled our shotgun base, according to the optical sight hole pattern on the Ruger. That’s all there was to it. We didn't even have to relieve the port, as there has been no problems with spent brass encountering the mount.
With this concept, one can now shoot iron sights, remove the mount, and switch to optics. When going back to the ATS, the zero should be the same. This is the answer to those who want to shoot .22 steel competitions in the limited category. It also makes for a nice light pistol for a back pack trip. I also believe that the Ruger Lite hole pattern is the same as Tactical Solutions hole pattern for their barrel, though the Ruger would take what is called a 648 screw, while the Tactical Solutions barrel would take a 640 screw.
So, what do you think? Would any of you like to see us produce this? We've got two working prototypes and they both work great. Please voice your opinion, as we wouldn't do it, should the demand not be great enough.
