Went out shooting with my cousin today and run into a major problem with my rifle. After shooting about 15 times today I put a round in the chamber went to pull the trigger and nothing happened. After removing my cartridge from my rifle I closed the bolt and the firing pin shoot forward like I pulled the trigger. Got my rifle home today and took it apart. I tried to go back through the instructions thinking a screw had backed out and allowing it to go off. I couldn't get the trigger to reset and the safety want engage. Has anyone run into this problem?
