You will notice the how complex this is and that it is a riveted unit. In addition some of the major components are forged and not just machined from stock. Now while I would like to make this, it is impossible to reverse engineer this without taking it apart. I have yet to find anyone willing to allow me to disassemble this unit. So we have studied the space available in the receiver to allow us to build a fire control system there.

This is a  picture of completed fire control mechanism with out the disconnector.

This system is designed to be safe and pass the ATFE tests. I hope this helps with the reasons for the design changes we have made.

The objects are still the same. That is discussing the design, prototyping and the building of small arms, their parts and accessories.

The first project is the Gustoff Volkssturmgewehr, model MP-507, and commonly called the VG1-5 in the states. This rifle was designed at the end of World War 2 by the German arms manufacturers and was to be issued to the home guard. For a detailed overview you should read Desperate Measures – The Last-Ditch Weapons of the Nazi Volkssturm published by Collector Grade Publications.

I have always wanted one of these rifles, however with a price tag of $35k to $53k it is way past my budget. So it is time to build one or at least a facsimile of one.

The first hurdle was to design a new fire control system – the original design is nightmarish to make, and still not change the overall appearance of the  rifle.

This is the solid model concept drawing of the fire control mechanism. This model allows me to look at part size and relationship.
