Installation instructions for the MOSIN NAGANT 91/30 & 91/59

Push the pin out at the front of the rear flip up sight. Remove the spring by sliding it forward and lifting it out. Slide the flange nut into the undercut at the rear of the sight where the spring was. Place the mount over the flange nut with the (2) 4-40 tapped holes toward the barrel end. Line the 4-40 holes in the mount up with the holes in the side of the receiver and put in the (2) 4-40 socket head screws. DO NOT TIGHTEN!!!

Place a pin, drill, etc. through the countersunk hole in the top of the mount and into the hole in the special nut. Move the nut around with the pin until the round part of the nut slips into the counterbore in the bottom of the mount. Put the 10-32 x 5/8 flat head screw through the mount and into the nut.

Tighten this screw and the (2) 4-40 screws. Put the 10-32 x ½ set screw down through the front tapped hole in the top of the mount and tighten against the receiver. Put the 10-32 x 5/16 set screw into the rear tapped hole and tighten. This screw can be used for some vertical adjustment. If you find your gun is shooting low, loosen the 10-32 flathead, tighten the 10-32 x 5/16 set screw and re-tighten the 10-32 flathead. For every ¼ turn of the flathead screw you will move approximately 8” at 100 yards.
