Installation instructions for the Mas 36

To install this mount, it is necessary to remove the rear sight from your Mas 36.

After removal of the rear sight file any burrs off of the .098 diameter pivot pin you removed when taking off the rear sight. Place the right bottom part of the S&K mount into the .350 wide slot at the rear of the receiver. Slide the .098 pivot pin into the hole on the receiver & then into the hole in the mount (it will not fit in from the left side). Tap the pin in with a punch until it is flush with the right side of the receiver. Insert the (2) 10-32 x 1/2 socket set screws through the left side of the mount & VERY LIGHTLY tighten. Insert the 10-32 x 1/2 socket set screw down through the top of the mount at the rear & tighten. Tighten the (2) side screws.
