ACE-MB-1 AKM STARVATION STOCK
Modular steel reinforced AK stock built around a $5 10x1 steel mending brace from a certain local hardware store. Basically a busted ass DIY knock off Jmac for peasants. Total build cost = $15. Enjoy! ~ <3 ~
materials
hardware
This stock is built around a specific set of mending braces. I don't know if it will fit others. You've got 3 choices depending on how fancy you wanna be.
All are measured 10 in. H X 1 in. W X .165 in. L.
The rest of the hardware, you likely already have.
- 2x M8x30 screws
- 2x M8x20 screws
- 4x M8 nuts
- 2x M5x20 screws
- 2x M5 nuts
- 4x M4x20 screws
- 4x M4 heatserts (optional)
filament
This stock was printed and tested with PA6-GF25 and SirayaTech PET-GF for the rigid parts and SirayaTech Flex TPU Air for the flexible parts. Use your own best judgement given your budget, equipment, and needs.
printing
Manufacturing this stock requires roughly 225 grams of rigid filament and 58 grams of flexible filament using the provided 3MF files - costing roughly $10 depending on the brand. It will take just over a day to print all of the parts successfully and assemble them.

orientation
3MF files are oriented correctly for clean and tough support-free prints. Print the shoulder pad mount with the flat part down. Print the cheek pad mount vertically (tallways). Print the receiver mount sideways at a 45deg angle on the chamfered face. Print both pads flat side down.
assembly
- Press M8 nut into the recess on the left face of the receiver mount.
- Press 2 M5 nuts into the recesses on the bottom face of the receiver mount. Thread an M5 screw just slightly into the nut from the bottom and use it the push the nut all the way into the pocket until it stops, then unscrew.
- Slide the mending brace into the cavity on the right side of the rear face of the receiver mount.
- Thread an M8 screw through the hole in the right face of the receiver mount all the way until it makes contact with the M8 nut of the left face, then tighten.
- Install 4 M4 threaded inserts in the holes on the top of the cheek pad mount and shoulder pad mount. (optional)
- Use the M4 screws to attach the cheek pad and shoulder pad to their respective mounts.
- Slide the shoulder pad mount with pad attached onto the other end of the mending brace using the pocket on the front face of the shoulder pad mount.
- Press one M8 nut into the pocket on the left face of the should pad mount.
- Thread M8 screw through the right face of the should pad mount until it passes through the M8 nut and tighten.
- Press 2 M8 nuts into the 2 pockets on the rounded face of the cheek pad mount.
- Align the cheek pad mount with the middle holes on the mending brace from the inside (right hand) of the stock.
- Thread M8 screws through the front face of the mending brace and through the nuts on the other side. Tighten. (optional)
- Slide the receiver mount into the receiver. Slide 2 M5 screws through the holes in the top of the receiver mount and screw through the embedded M5 nuts.
The pockets that the mending brace slides into are intentionally tolerant to account for shrinking. If there is play, you can print one of the shims and reinstall the brace with one.
