Modification instructions for Rear Sight Clearance on the M-39 “Finnish Heavy Barrel.” The rear sight area in the stock must be relieved for the barrel to seat.

Step 1: Place the barreled action in the stock for positioning. The rear sight assembly on the M-39 rifle will not allow the stock to seat properly.

Step 2: Material must be removed from the shaded areas for the stock to seat properly. Cut a slot approx. 1/16” x 5/16” wide x 3/8” deep on both the front left and                                                 

front right sides of the stock as indicated by Figure 1-A. This may best be accomplished using a Dremel type tool with a cutter.

Step 3: To obtain the correct clearance, simply file approx. 1/8” off
the corner as indicated in Figure 1-B.

Step 4:  Your barreled action should now drop into the stock.

 

Stock Adjustment Installation

Step 1: Due to the many variations of the Mosin Nagant and the range of the angle between the barrel and receiver, a washer may be needed to improve the position of the barrel in the stock.

Step 2: Once you have determined that a washer will be needed for the proper fit, disassemble the firearm as instructed on the previous page. Place the top receiver screws through the receiver then slide the 5/16” washer provided onto the end of the bolt.

Step 3: Next, insert the barreled action with the bolt and washer into the top of the stock and insert the magazine assembly into the bottom of the stock.

Step 4: Tighten the bottom magazine assembly screw first then the top receiver screw. When the washer is installed, there might still be a small gap between the barrel and the stock. This will not affect the performance of the firearm.

 

Cartridge Interrupter Installation

Step 1: Due to the many variations of the Mosin Nagant you may need to remove some material from the stock wall for the cartridge interrupter to work properly.

Step 2: Use a Dremel or similar tool to remove material from the stock wall.

Step 3: The side wall of the stock gets thicker as it moves down the side, be sure to angle the Dremel so the wall has the same thickness on the top as it does on the bottom.
