I had not considered cocking it, but would have run into it some point... Was thinking it thru only from an air path perspective...
I had been contemplating a riser plate, thick enough for the breech screws to attach to, yet not allow them to protrude into the striker path. Solder the riser plate to the tube.
About the 2 oring barrel mount.... wouldnt the space between the rings-dead space at this point-- bleed off some of the air? better off to cut the barrel back past the TP? or would you need to cut a new leade at that point?
back to the drawing board in my head.....
