Hello all. My blow back luger has broken and wonder if any one can help. After starting firing it would not cycle manual cocking got it working again and after 3 or 4 shots it blew out all the CO2 and jammed.
After cycling the action it spat out a small brass screw.
This is obviously the cause of the problem but I have no idea where it goes or how to strip it.
Any ideas please?
