Cleaning, Lubrication and Maintenance

Overview

Routine maintenance is essential to keeping your Model 700 Ultimate Muzzleloader in top condition for years to come.

Cleaning, Lubrication and Maintenance

WARNING! Before cleaning, make sure your firearm is completely unloaded 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 bore should be cleaned before loading and discharging the firearm the first time.

Lubrication:

Over-lubrication should be avoided at all times. A light application of Rem™ Oil or Remington’s MZL™ Patch & Lube 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 Rem™ Oil or Remington’s MZL™ Patch & Lube. 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™ Oil is strongly recommended. The use of improper lubricants may lead to property damage, personal 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. 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. Open the action by rotating the bolt upward then pulling the bolt fully rearward.
  4. Ensure the firearm is not primed by looking into the ejection port, visually checking the loading port and breech plug nipple for an ignition source.Remove the Remington U.M.L. Ignition Source from the firearm.
  5. Ensure there is not a powder charge and a projectile in the barrel or any obstruction by inserting the ramrod with jag provided into the bore until it stops.  If the single wide notch near the end of the ramrod is even with the muzzle, then the firearm is unloaded and does not have an obstruction. See Picture A.
