My fn250b has a small tab/lever just below the nail feeder (with no nails in the gun the lever will be just below the nail pusher). Push on the lever with your thumb and the nose will open. This lever is held in place with one screw. If the tab/lever breaks off at the screw or if the screw falls out the lever and its spring will fall off and the front nose will just be loose/ nails will be pushed out. If someone rigged a part to keep the nose closed, you can order the correct parts at www.toolpartsdirect.com. Not really needed however because the gun does not jam that often. Good luck

Worn trigger and or worn firing valve. Remove the trigger and look for wear on contact surfaces (worn pin that holds trigger, worn inner lever inside trigger, worn or loose firing pin in valve ). Easy test for worn trigger. Remove the nails, remove trigger, fire the gun against wood with finger to test for proper action. If it works better without trigger, consider replacing trigger with new (I would also order the oring repair kit that includes the firing valve )
