Aliens Smart Gun Parts

thingiverse

Here are a number of dress up parts to convert a deactivated MG42 gun to look like the smart gun from aliens. These may work with airsoft versions of the gun but I don't know if they will be sized the same. The disc, disc standoff and drum cover are dress up parts for the machine gun drum magazine. The guard covers the trigger assembly and the block attaches to the rear of the gun and allows the motorcycle brake lever trigger to be attached as in the pictures. I epoxied all of the drum parts together and attached them to the real drum magazine with screws. The disc standoff is simply glued to the disc and gives enough space so that the drum magazine doesn't interfere with the catch mechanism on the main body of the gun. The rear block fits snugly into the back end of the gun and I have not needed to add any attachment screws. The block has a hollow section to enable cabling to run from the trigger to the motorbike brake assembly the trigger guard is attached via a couple of small machine screws that I tapped into the trigger assembly. it is held very tightly once all of the rest of the block and trigger cable tubing is in place. the diameter of the tube that runs between the trigger guard and the rear block is 20mm. I made this from steel tube rather than use a printed tube as I had it in stock. It wouldn't be too hard to model the tube and print it though. For the handguard that is attached to the rear block I used 50mm diameter aluminium tube cut to size and screwed through the extrusion at the rear of the block as shown in the pictures. EDIT 01/05/19: I added a model of the muzzle attachment. Mine is turned steel tube and the model is an exact replica of that.
