The Marlin model 336 rifle is a very popular gun used for big game hunting for years.  It's a fantastic rifle, and I love mine.  But recently I've had a problem where after I load ammo and work the action, it gets stuck.  The only way to fix it is to disassemble the gun and put it back together.  How does it happen?  This video explains it.
