Scout AKM Buttstock V1.1.2: Laffs Dynamics

A lightweight, fixed AKM buttstock designed for the use of optics. The overall length of the design is ~12mm longer than that of the soviet version. The cheek comb is also ~12mm higher than OEM, to aid in use of side rail mounted optics. (See Note 2) The hollow portion of the stock has printed reinforcements for enhanced durability, reducing damage from impact forces. 

This design either can be printed as two halves (plus the buttpad) or a single part, for printers with build volumes as large as CR10s. 

Update V1.1.2: Updated buttstock shank for tighter fitment within rear of the weapon receiver. Updated print settings based off the more common Ender 3 3D printers. Updated name of designer.

4x Dowel Rods: 1/4in diameter, 30mm long (See Note 3)

Gorilla Clear Glue 

Assembly:

NOTE: Skip to step 5 if printing the single part stock.

1) Lightly spray both stock mating faces and dowel rods with water. (Gorilla CLEAR glue cures with moisture.)

2) Apply gorilla clear glue into the dowel rod insertion holes, then press the dowels in.

3) Apply the adhesive the the mating face and dowel rod insertion holes of the stock half (Or whichever half doesn't have the dowel rods inserted.)

4) Press both stock halves together. Wipe away any adhesive squeezeout, and clamp together/put something heavy on the two halves for 2 hours minimum.

5) Screw the buttpad onto the stock's end. 

6) Press the buttstock into the rear trunnion of the AKM, and drive the mounting screws, holding the buttstock in place. 

Notes: 

1) Should the OEM rear trunnion stock retention screws be of a different diameter, simply drill the holes in the stock to the proper diameter before mounting. Doing this avoids the risk of cracking along layer lines, should you drive larger screws in. 

2) With an OEM buttstock, many AK weapon platform users have criticized that side rail attached optics are mounted too high, forcing users to use a "chin weld" instead of a cheek weld when aiming down sights. The higher cheek comb on this stock still allows the use of iron sights, whilst aiding in side rail attached optics usage. 

3) Due to the use of only 4 dowel rods (For 2 Part Stock Only) it's recommended to use metal based dowels to avoid flexing between the two halves. (Steel, brass, iron, etc.)
