M4 stock and MP5k adaptor

thingiverse

I wanted to outfit my custom-made Galaxy MP5k submachine gun with an authentic M4 stock without breaking the bank, so I decided to create one from scratch by designing and 3D printing it instead of buying one on the market. My prototype was printed at a precise resolution of 0.2mm using three outer shells and an interior infill percentage of twenty percent on my high-performance CTC printer. Instead of investing time in modeling and printing the buffer tube, I cleverly opted for a durable piece of conduit measuring 25 millimeters in diameter, which I securely fastened to the endpiece with reliable set screws. To assemble the stock's adjustable rail, I employed strong PVC welds that effectively attach it to the central tubing, guaranteeing stability and a sturdy hold on my submachine gun.
