Update on the VG1-5 project

We have been working on the fire control group and once again have made a few changes for more reliable operation and safety. We continue to have issues with the disconnector operating properly. There were issues with the hammer spring improperly contacting the disconnector. An additional problem came about with insufficient spring pressure to hold […]

The MG-09 light machinegun

In answering question concerning the post on the AR-10 belt fed light machine gun Ihave spent some time going through the ” The Armalite AR-10″ book. On page 314 of the book is a picture of a MG-09 light machine gun. The funny thing is that I had just seem that same weapon. It was […]

Building an MP-44 semi part 2

We have shipped the test MP-44 trunnions to Pete and while we are waiting for his report back we are filling our time working on making stamping dies. In this case all the pieces are sized and we […]
