Trouble with m203's
 

Well I got my new m203 short for Christmas. The problimb is it doesn't launch the shells. When I load the shells with gas and bbs and lock and load the m203 does not fire. But the shells will fire when I press in the button without the launcher they go off. Any help will be greatly appreciated.

The launcher isnt supposed to launch the shells, but rather fire the shell inside like a shotgun.

Does your M203 have a trigger safety?

If so, the safety might be on when you made your attempt.

If this is the case, disengage the safety and try again.

Pull REAL goddamn hard, most M203s have a 15lb trigger pull, 20-30 if your using CO2
