Here At Gun Lab we actually have a number of projects going on. While we are waiting for our heat treating to come back for the VG1-5 and AR-180b parts we started on the AR-180B upper receiver. This receiver is design to fit on the Nodak-Spud lower as well as the AR-180B lower and the original AR-180.
The project was started July 20th when a friend sent me a original flat for the AR-180. That evening I sat down and started the solid model drawing for the upper receiver. It was not a priority project here and was put on the back burner until the projects on the mill were completed. However, by July 30th I had completed the solid model and had completed the first set of basic modelling for the stamping die.
This first picture is of an original AR-18 flat that has had ribs pressed in.
This picture shows what it would look like after the next stamping. The basic shape is cut out.
In looking at an original AR-180b upper you can see a few of the manufacturing changes. Looking at these pictures and at the actual part you can see that a laser cutter was used versus stamping them out. The cost difference is huge.
Once the basic design is completed we start working on each component of the design and changing the parts and assembly as we go along. Finally we come up with a working model.
To the final products.
This is were we stand now on 8-17 and starting from 7-20. Less then 30 days from concept through design and modeling to programming and machining.
