To disassemble a Stevens Model 300 shotgun, first ensure the firearm is unloaded by checking the chamber and magazine. Next, remove the forearm by unscrewing the screw located at the front of the receiver. Then, unscrew the trigger guard and remove it, which will allow you to take out the trigger group.
