XS Sight Systems is well-known for its tritium Big Dot and 24/7 sights for semi-automatic handguns, revolvers and rifles. The U.S.-made units are machined from steel and come neatly packaged with a polymer drift and thread-locking compound to facilitate user-installation at home even if you don’t have a sight pusher. XS also makes a nifty scout scope mount for Mausers that does require a bit of minor gunsmithing, but is not too far beyond the guy with average skills. It also has Picatinny rails for lever-action classics such as Marlin’s 1894 and 1895 that allow the mounting of scout and conventional optics and add to the guns’ factory sight radius by moving the rear sight mounting position to the rear of the receiver, rather than on the barrel, which is where a unique screw assembly fits into the factory sight’s dovetail to secure the rail. It’s all easier to mount than it is to describe and can be done on the kitchen table.
