Instructions for the BRAZILIAN 1908 MAUSER

Install the (2) 10-32 set screws into the mount from the top (stop them when they are flush with the bottom). The 10-32 x ½ set screw goes in the front & the 10-32 x 3/8 set screw in the rear. The 10-32 x 3/8 set screw that threads into the hole where the ring goes needs to protrude from the bottom .053 or  1 ¾  turns of the thread. To get the set screw flush with the bottom of the mount hold something that is flat up against the bottom of the mount where the set screw will protrude.

Tighten the screw with an allen wrench until you can feel pressure on the flat plate you are holding against the screw hole. Now hold the mount in your left hand with the top up & insert the long end of an allen wrench into the set screw being careful not to rotate the screw. Rotate the mount until the short end of the allen wrench is at the12:00 position. Turn the allen wrench 1 ¾ turns. You will only need to adjust this screw if the rear of the scope is low or high & you will have to remove the scope to do this. If you are shooting low you will need to turn clockwise – high counter-clockwise. If you have to adjust this screw - move in very small increments. One revolution will move you 32 inches at 100 yards.

Center the mount over the rear sight with the two 6-32 screw holes in the side toward the front of the gun. Lower the mount onto the rear sight area. Line the 6-32 tapped holes in the mount up with the holes in the side of the receiver. It is very important that these holes line up to keep from damaging the threads when the screws are installed. Install the two 6-32 x 5/16^th socket head screws in these two holes. Snug them down but do not tighten. Insert the 10-32 x ¾ flat head screw into the mount & tighten. Tighten the front 10-32 x ½ set screw. Retighten the flat head screw. Boresight & do your final adjustments with the turrets. Do not move the 6-32 screws unless the 10-32 flat head screw & the 10-32 x ½ set screw are loose as you will damage them.
