Cleaning, Lubrication, and Maintenance

Overview

Routine maintenance is essential to keeping your firearm in top condition for years to come.

Lubrication and Maintenance

WARNING: Look into the ejection port and check the chamber and the magazine to make sure there are no shells in the firearm before cleaning or storing.

Cleaning

The amount of shooting between cleaning will vary greatly depending on climate, weather conditions, ammunition used and the amount of lubrication.

The Model 11-87™ Autoloading Shotgun and Model 1100™ Autoloading Shotgun are gas-operated firearms. Gas operation provides significant recoil reduction by bleeding gases off the barrel to pressurize a piston which unlocks and functions the action. These gases carry combustion residues which can foul the magazine tube and/or piston/piston seal assembly, particularly when the firearm is subjected to: cold damp conditions, over-lubrication or use with ammunition that is not clean-burning.

To Clean the Barrel

  1. Use the instructions and equipment provided in a good cleaning kit. For recommendations, see your Remington® Authorized Service Center.
  2. Select the correct gauge cleaning brush and attach the brush to the cleaning rod.
  3. Put the cleaning brush into gun-cleaning solvent.
  4. Push the cleaning rod through the barrel several times.
  5. Remove the brush from the rod, attach tip with cleaning patch and push through the bore.
  6. Repeat several times, using a new, clean patch each time until the patch is not dirty.
  7. Remove all of the shooting residue from the locking notch in the barrel. See Picture 26.

Over-lubrication should be avoided at all times. A thin coat of Rem™ Oil is all that is needed to prevent the possibility of rusting. See Note below.When the firearm is to be stored, it should be carefully cleaned and thoroughly oiled. Outside surfaces should be wiped with a light coat of Rem™ Oil occasionally. See Note below.

When firearm is to be reused, all excess lubrication must be removed. The chamber and bore must be thoroughly wiped dry.

NOTE: Remington Rem™ Oil is available from your local dealer. If your dealer is out of stock, ask him to order Rem™ Oil from his Remington distributor.
