Is it a model 500 pump action? If so, or for that matter with most shoguns, you unscrew the cap over the magazine tube. Place the butt of the gun on a low table or other solid surface with the fore end at a reasonable height. Do this AFTER ensuring the gun is unloaded and it is on safe. Now, turn the cap on the end of the mag tube counter clockwise to unscrew it. Then remove it and set it asside. Now you should be able to pull up on the barrel which will allow the barrel ring to clear the mag tube. Then you twist the barrel to free the guides and pull it free. Good luck.
