A couple of pictures of the rifle with the stock extended. This is one with the stock […] Here at gun Lab what we do is study weapons and at any time you could come across anything. A set of EM-2 locking flaps, a Destroyer carbine, a Vickers cut away lock, Hand drawn prints for a weapon or a French MAS 36 22 trainer cartridge adapter. Anything and […] Op 7 has been completed. This is a major mill stone on making the MP-44 trunnions. The rest of the machining will be done on the manual mill.

This is […] Operation 6 has been completed on the MP-44 trunnions. A couple of problems were noted. The first is the difference in length on the front of the trunnions and the second was the fit up of the locking shoulder.

With the first 5 operations completed we will be starting on op6 soon. This is a master cam simulation of the process. […] The next machining operation has been completed on the trunnion.
