DIY AK bullpup progress. Here are some pictures of my recent progress. I’ve begun disassembling my AK. I’ve taken more pictures of the dimensions so that I can more easily acquire the wood shape I need while I’m in the factory.
I found out that the extension on the plastic receiver is really part of it. So I’ll work with it, since it is a more secure point of attachment when I make the wooden butt. The butt will be a curved cut piece of wood at about 21mm thick. Its hollow at the part that fits the dynamo/motor and trigger guard, but it won’t be in the space between the two (where it will be still solid wood.
The butt being wood, I’ll find something to cover it or shield it. I need a metal clip to cover the main securing point.
Right now I’m stuck because I don’t have any materials. I have to find time to go to the factory and get the following:
- Discarded Office Floor Rugs for my work surface
- Wood Pieces for the 2cm butt plate.
- metal pieces for trigger mechanism.
- Redundant pieces for multiple tries.
- Thick wire to hold up paper targets for practice
- I also need small tamiya connector types.
AKs are still the most bang for buck. Being able to convert them to bullpup, availability of parts, highest capacity mag, the cheaper price, and thicker built version 3 gearbox.

measure for the 2cm butt. Its got to curve, hollow out for both the trigger guard and the motor. I plan one solid block. Anchoring points is at the back, the base of the motor and the trigger guard. What ever wood I can get my hands on.

measuring if I can convert my older Nicads into One stick type.
 the only part I’ve finished making, given the materials I have. |
MP44. The internals are pretty good, I’m wondering what would happen if I changed the spring to SP140 or SP150 and moved the Ver2 gearbox to my G3?
Springs? Why don’t companies have a standard way of measuring resistance? There are tools in measuring how much force is needed to compress a spring. As to efficiency of energy return after compression, now I leave that to brand.
In my Game Theory class, when companies don’t have a “Standard” by which to measure each other, it is a deliberate strategy so that its harder to compare each products performance. This gives the “Good” brands more power.
if I were an up and coming spring producer, I would try to use a easier metric to measure. Simply measuring with mechanical properties like joules and pascals would have been enough. Once you have the formula for Joules, you can use it to figure out speed of various BB weights.
