Lubrication and Maintenance

NOTE: The chamber should be cleaned before loading and firing the firearm the first time. Follow the cleaning instructions below.

Over-lubrication should be avoided at all times. A thin coat of Rem™ Oil 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.

When the 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.
