How do you disassemble a model 31 Remington shotgun?

Answer 1

Make 100% sure it is unloaded before you start. Open the action a little bit, then unscrew the barrel nut until you can see space between the plunger and the detent. Turn the barrel and magazine assembly 90 degrees and pull it out (yes, the 31 is a takedown gun). Push out the big pin in the receiver from right to left (looking down on the gun from firing position). Turn the gun upside down. Push the trigger assembly toward the front of the gun until it aligns with the slots, and pull the trigger assembly out of the gun. For BASIC disassembly, most users should stop here. The slide/bolt assembly is a little more complicated, and unless you have some patience, experience, or mechanical knowhow, getting them back together can be a little frustrating. For those who want to go farther, look up a copy of "The NRA guide to Firearms Assembly," or find a M31 manual on E-bay for under $10.
