Long overdue update on the project. Found a tank with a little bit of air in it, so could finally test my modifications to the BT-4. My goal was to eliminate blowback but only removed the hammer oring and added an oring to the value. Turns out that’s all I needed to do. The gun is now bolt action, needing to be manually recocked after every shot.
I need to finish building my custom hopper now and figure out how to feed the 10rd tubes into it. And the I’ll be ready for the big reveal!
