Post subject:  Gwinn Arm gun

Another toy from yesteryear. When I was a kid our library had a copy of Smith's Small Arms of the World, I think that was the first time I had seen a drawing of an experimental arm that was being developed as a survival gun for the military in the 60s. The Gwinn Arm Gun was never officially adopted but it is pretty neat PDW concept. They sold these .223 caliber survival guns on the commercial market in the 70s and 80s. Easy to feed as it used Colt AR-15 magazines. Technically a handgun it can pivot left or right, it ejects straight out of its top. Over the years I have owned several. Right now I only have this one, which is like new in the box with all its paperwork.

This is the company that eventually became Bushmaster, if you have a Bushmaster AR and look at the snake you will see the outline of this gun within the snake. This is the gun that started this company. They made a shoulder stocked full rifle version of this action as well, I had one but it was not very reliable so I let it go.

Here is the image I spoke of.

I remember reading about it back then. I never could get my head around how you were supposed to hold the end against your forearm. SW

Had one of those years ago, you're right not very reliable and definitely LOUD. They were supposedly a prototype for a pilot or aircrews survival weapon. I ended up selling/trading for something else and was glad I did.

I have had examples over the years that worked great and others not so much. I noted with the problematic ones soft parts that deformed, I think there were QC issues with some batches, but others were great.
