BT TM-15 issues
Recently i experienced an issue with my BT TM-15, when i screw the tank in the bolt goes forward without firing and sits open leaking massive amount of air till i remove the tank, then bolt(or action) returns to the resting position. I tore the marker apart and oiled it real good, but it still is leaking, Checked all o-rings and am still unable to find the source of the problem.
If you have any ideas or fixes please tell me. (Note that i was unable to open the actual bolt due to the sealed action the BT TM-15 has.)
