The Boxer clone has the same 510 setup as the Frankenskull clone. It works great with their attys but not with standard attys which won't make contact. Some attys you can screw the pin out a little to make contact, but the best solution is to shim up the 510 pin on the
mod. Cut off a thin piece of the squonk tube, just enough to make a washer. Remove the 510 pin and place this under the existing washer and put it back together, making sure you don't leave out anything. It should now fire with a standard atty.
