Cleaning, Lubrication, and Maintenance

OverviewEdit section

Routine maintenance is essential to keeping your Bolt Action Model 783 firearm in top condition for years to come.

 

WARNING! Before cleaning, make sure your firearm is completely unloaded (both the chamber and the magazine) and engage the safety mechanism by placing the safety lever in the “S” or "SAFE" position. Failure to follow these instructions may lead to property damage, personal injury and/or death.
WARNING! After each use, follow the lubrication and maintenance directions in this Owner’s Manual. If the firearm is immersed in water, it must be thoroughly cleaned and lubricated as soon as possible. In case of saltwater immersion, first flush all parts with fresh water, then dry, clean and lubricate the firearm. If the firearm does not function properly, have it
checked and corrected by a Remington Authorized Repair Center before further use. Failure to follow these instructions may lead to firearm malfunctions which could result in property damage, serious personal injuries and/or death.

Note: The chamber and bore should be cleaned before loading and firing the firearm the first time.

Lubrication:

Over-lubrication should be avoided at all times. A light application of RemTM Oil helps to prevent rusting.

WARNING! Excessive use of a lubricant could adversely affect the function and safe operation of your firearm. Failure to properly maintain your firearm can not only damage
your firearm, it can expose you and others to unnecessary risks of personal injury or death.

When the firearm is to be stored, it should be carefully cleaned and thoroughly oiled. Outside metal surfaces should be wiped with RemTM Oil occasionally. When the firearm is to be reused, all excess lubrication must be removed. The chamber and bore must be thoroughly wiped dry. For safe and dependable operation of your firearm, the barrel and action must be cleaned periodically.

WARNING! The use of nonrecommended lubricants or solvents could adversely affect the function and safe operation of your firearm. Do not use congealing lubricants. The use of noncongealing lubricants such as Rem OilTM is strongly recommended. The use of improper lubricants may lead to property damage, personnel injury and/or death.

NOTE: Remington’s 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.

To Clean the Barrel:

WARNING! Unload the firearm before cleaning. Look into the ejection port and visually check the chamber and magazine to make sure the firearm is completely unloaded. Always wear eye protection when handling, disassembling and reassembling the firearm. Failure to follow these instructions may lead to property damage, personal injury and/or death.

  1. Always keep the firearm pointed in a safe direction.
  2. Engage the safety mechanism by moving the safety arm fully rearward to the “SAFE” or “S" position.
  3. Remove the magazine box from the firearm by pressing the magazine latch release button while pulling the magazine box from the magazine well. See Picture 13.
  4. Open the action by raising the bolt handle.
  5. Disengage the bolt stop by pushing the bolt release button while sliding the bolt assembly rearward until it is clear of the receiver. See Picture 10.
  6. Look into the ejection port, visually check the chamber and magazine to make sure the firearm is completely unloaded.
  7. Use the instructions and equipment provided in a quality cleaning kit such as a Remington Cleaning Kit. For recommendations, see your dealer or a Remington Authorized Service Center.
  8. Saturate cleaning patch with Brite Bore™ or equivalent.
  9. Attach the patch to a cleaning rod tip.
  10. Pass the patch through the bore from the chamber end to the muzzle several times removing loose residue and fouling.
  11. Select the correct caliber cleaning brush and attach a brush to the cleaning rod.
  12. Spray bore brush with Brite Bore or equivalent.
  13. Push the cleaning rod through the barrel several times.
  14. Remove the brush from the rod and attach a tip with a cleaning patch.
  15. Push the cleaning patch through the bore.
  16. Repeat steps 11 through 15 several times, using a new cleaning patch each time until the patch is removed from the barrel without fouling residue.
  17. Push a clean patch saturated with Rem™ Oil through the barrel.
  18. Push a clean dry patch through the barrel to remove excess lubricant.
  19. Apply a light application of Rem™ Oil to the outside of the barrel with a soft clean cloth.

WARNING! After cleaning, Make sure the barrel is free of obstructions, see “To Check the Barrel for Obstructions.” Discharging the firearm with a dirty and/or obstructed barrel may lead to property damage, personal injury and/or death.
