This may take some time to complete so I am going to take pictures of the progress. P90 style BB gun, maybe full auto or burst fire, depends how it works, or maybe not at all.



Cut out the rough body shape from 3/4" plywood. Will be in two halves screwed together.

Been working on a block of aluminium I found, it houses a cylinder which will block the BB's when fired, it will be a 4 shot burst if it works 1" stainless steel chamber finished as well.

Had to change it a bit as I realized there wasn't enough pressure in the barrel to operate the blocking cylinder, had to move it to the pilot supply which stays at full pressure. Tried a gravity fed mag but that won't work unless it has some pressure on top to keep the BB's down when firing, finally got the burst fire to work




Looks like something I made a few years ago

How many shots per second do you think you can achieve? It looks compact, and will be excellent with wood placed. I like it.
In my automatic weapons, I use pressure in the magazine where the ammunition is housed. A small pressure of less than 1 bar is enough to put the ammunition in the firing tube, even against gravity. It is necessary that the ammunition have a little adjustment in the charger tube.

If it feeds ok I will try the magazine horizontal
