Trigger locked up

[sam beach WSW]

So my APS Demolition rifle had a problem yesterday after a practice game with my team. I went to fire off my rifle to clear my chamber and the trigger was locked my first thought was a semi auto lock up. So I flipped it to full auto and the trigger was still locked up I tried everything I could think of to free it but nothing worked. Does anyone have anything that might help.

Apart from opening it and taking a look, not really.

Safety lever on the gearbox stuck in the 'safe' position ? try giving it a damn good shake to see if it frees off. Otherwise it's removing the box time
