Hi all, to say the last 2 hours of my life have been rocky would be an understatement but I'll cut to the chase. How does one remove the upper reciever of this shotgun from the lower? I made the mistake of removing the rear most pin which sucked my trigger up into my reciever when I cycled the action. As it stands I am unable to fix the problem externally and have removed everything (barrel, bolt, stock, etc) in an attempt to find how it comes apart but to no avail. Any and all help would be greatly appreciated 
Apologies if the formatting is poor, I am on mobile because I refuse to leave the garage until this is fixed.
