Remove stock from shotgun
To remove the stock from an Ithaca model 900 SKB shotgun, first ensure the firearm is unloaded. Then, locate the stock bolt, which is usually found at the rear of the receiver. Use the appropriate tool to unscrew the stock bolt, and gently pull the stock away from the receiver. Be cautious not to damage any components during the removal process.
