Do any of u know anything about these. I got a chance to get one and have never seen one. It's all blk kinda weird looking. The charging handle spring is missing. I have searched the web and can't find any parts or good info on it. Any help would be great.
Gwinn was the origin of what is now Bushmaster and was offered in both rifle and pistol configuration. I have owned both varieties. They usually work VERY well unless someone has tinkered with them. Surplus M16 parts were in all the ones I had a chance to look at or fondle. Tinkering usually led to illegality. ( full auto ) If you are a shooter I would suggest you "pass" on purchase as there are more modern and cost effective options.
