How to Take Apart a Sears .410 Shotgun

Save

The Sears Model 21 is a .410-gauge pump-action shotgun manufactured by Hi Standard and sold by Sears, Roebuck & Co. during the 1960s. The guns sold relatively well and were considered at the time to be a good value for the money. Disassembling the Model 21 is relatively simple, and regular maintenance should be performed on the guns because of their age.

Things You'll Need

  • Long-handled screwdriver
  • Small screwdriver
  • 1/8-inch Allen wrench
  • Point the gun in a safe direction and verify that it is unloaded. You can do this by cycling the pump several times to make sure that no shells are ejected. Be sure to keep your finger away from the trigger during this step.

  • Remove the butt plate located at the very back of the shotgun stock by removing the two holding screws. Unscrew the stock bolt a couple of turns using the long-handled screwdriver to loosen the tension on the trigger guard retaining pins.

  • Push the two trigger guard retaining pins out of the side of the receiver -- the metal section of the shotgun directly forward of the stock -- with the small screwdriver; the trigger assembly should drop out.

  • Remove the magazine cap using the Allen wrench. The magazine cap is located on the front end of the magazine tube, which is just below the barrel and runs parallel with it. Push forward on the magazine tube to remove it as well as the spring and follower.

  • Hold the gun with the bottom of the receiver facing upward and move the bolt assembly approximately 1/2 inch from the closed position by gripping the pump action and pushing it toward the front of the gun. Squeeze the front end of the left cartridge stop toward the center of the receiver, enough to clear the action bar. Close the bolt by pushing the pump action all the way forward.

  • Push forward and upward on the action until the action bars clear the bolt assembly. The bolt will now drop out of the ejection port, located on the right side of the receiver.

Tips & Warnings

  • Always keep the gun pointed in a safe direction.
  • Always keep your finger off of the trigger and out of the trigger guard while performing firearms disassembly or maintenance.
  • All firearms are deadly weapons. Consult your operator's manual for safety guidelines before attempting disassembly.
