Just about done.
Stock screw removed.
The bent c-washer captures the screw so you can take down the rifle for transport.
This is a rough approximation of how it loads.
BBs are inserted into the tube.
When the muzzle is raised a BB rolls into the valve assembly.
Without the barrel in place it’s easy to see how the magnet works.
The BB captured by the magnet.
The barrel at the receiver end. 4 ports for gas flow.
Again, a BB dropped into the hole is stopped by the barrel.
When the rifle is cocked by moving the hammer forward the BB drops down. When the rifle is fired the barrel moves back, picks up the BB and knocks open the valve.
As you can see here, the barrel sticking through the valve chamber would have knocked open the valve and gas would flow through the ports and propelled the BB out the barrel.
I think I may just clean the 3030 and see if I can get it to work before thinking of any refinishing. Now where’s my 5 gallon steel pail?
