Hi iv got a huge problem with a proto slg , the bolt will not push forward in the breech it seems like the bolt is too big for the gun im not sure if it is a dud iv tried everything as well as taking off all the o `rings and still no joy just to note that i have a fresh battery in and it is turned on when i am trieng to push the bolt foward while pulling on the trigger and the sear is mooving ,
The marker did work fine but all of asodden stopped working and it will leak as well if gassed up .
