WARNING! Only use the specified cartridge type and caliber of projectile specified for your firearm as designated on the barrel.  Use of an improper caliber or ignition component in your firearm could result in property damage, personal injury and/or death.

The Safety Mechanism:

The manual safety mechanism of your bolt action firearm provides protection against accidental or unintentional discharge under normal usage when properly engaged and in good working order.

This safety mechanism is not a substitute for following the rules of safe firearm handling.  The safety mechanism blocks the trigger, preventing the trigger from being pulled when fully engaged in the "S" or "SAFE" position.

The safety mechanism is located on the shooters right towards the rear of the receiver.  To engage the safety mechanism, pull the safety lever fully to the rear toward the "S" position until the safety arm stops.  See Picture 4.

ml pic 4.PNG

Always engage the safety mechanism by moving the safety lever fully rearward before handling, loading or unloading the firearm. 

Do not touch the trigger while moving the safety mechanism.  Your fingers and all other objects should be kept outside of the trigger guard and away from the trigger until you are actually ready to discharge the firearm.

Never attempt to pull the trigger when the Safety Mechanism is activated in the "S" or "SAFE" position.

When you are ready to discharge the firearm, disengage the Safety Mechanism by pushing the safety arm forward to the "FIRE" position, marked with a "F".  You have now disengaged the Safety Mechanism and the firearm is ready to FIRE.  Se Picture 5.

WARNING!  The firearm will discharge when the trigger is pulled and the safety mechanism is OFF or in the "F" or "FIRE" position.  Failure to control the muzzle direction of the firearm when it is discharged may result in property damage, personal injury, and/or death.

Even when the safety is engaged in the "S" or "SAFE" position, careless handling may cause the firearm to discharge.  See the "Ten Commandments of Firearm Safety".

Additional Features:

In addition to the manual safety mechanism, the Model 700 Ultimate ML rifles incorporate passive features providing additional protection against accidental or unintentional discharge under normal usage and when in good working order.  These passive features such as the firing pin system, steel alloys and/or their metallurgical treatments, the sear, the trigger engagements, the bolt lock-up system, the breech lock-up system, head space, and the trigger guard all work without direct input from the user as long as your firearm is kept clean and in good working order.

WARNING!  Do not alter, modify, bypass, or render these safety features inoperative.  Altering the firearm's safeties may lead to property damage, personal injury and/or death.

The Locking Device:

This firearm was originally sold with a key operated locking device to assist the owner in protecting against unauthorized use. These are storage locking devices. The firearm should be completely unloaded when stored or not in use.

These locking devices DO NOT eliminate the need for safe firearm handling and storage, including keeping this and every firearm unloaded and locked in a secure place when not in use. Read and follow these and other safety rules in this instruction manual. Failure to read, understand, and obey these rules can result in serious personal injury or death. See The Ten Commandments of Firearm Safety, in this manual.

Keep your locking device engaged when your firearm is not in use. Keep the keys in a secure place, inaccessible to others. DO NOT leave your keys or any ammunition components with your firearm, which should be kept unloaded and locked in a safe place. See Picture 6.

To secure your firearm with an external locking device, See instructions provided in packaging.

The Bolt Assembly:

The bolt assembly locks the ignition source into position, containing the ignition pressures.  The bolt assembly is a striker system, manufactured specifically for your firearm to maintain proper head space (distance between breech plug and the bolt head).

To Install the Bolt Assembly:

  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. Before inserting the bolt assembly into the receiver, make sure the firing pin assembly is cocked.  When cocked, the firing pin cocking arm will be located in the small cocked notch.  See Picture 7.
  4. If the firing pin assembly is NOT cocked (as shown in Picture 8), cock the assembly by holding the bolt body steady while turning the firing pin assembly clockwise until the cocking arm is resting in the small cocked notch as in Picture 7.

  1. Disengage the bolt stop by pushing the bolt release button while sliding the bolt assembly fully rearward until it is clear of the receiver.  See Picture 9.

The Trigger Assembly:

Pulling the trigger DISCHARGES the firearm.

The Model 700 Ultimate ML rifles are equipped with a custom designed adjustable trigger assembly, the X-Mark Pro.  The trigger assembly is a single action system which has been set at the Remington Factory for Optimal trigger pull weight.  The factory settings provide a crisp, clean trigger pull for superior out-of -the-box accuracy for hunters, plinkers, and general target shooting.  Rifles with trigger pull weight settings lower than the factory setting (below 3 lbs) are considered "Target" firearms, used only for precision competition shooting,under firing range or bench firing conditions. The Model 700 Ultimate ML rifles trigger pull force (weight) can be adjusted within limits.

All repairs to the trigger assembly must be made by the factory or a Remington Authorized Repair Center.

WARNING! Never place your finger on the trigger unless you are ready to discharge or fire the firearm.  Careless placement of a finger on the trigger may lead to an unintentional pulling of the trigger and discharge of the firearm.  This may lead to personal injury, property damage, and/or death.

WARNING! Never manipulate, adjust or change any of the internal components of your firearm unless specifically directed to do so in this instruction manual.  Improper manipulation of any internal component may effect the safety and reliability of your firearm and may cause property damage, personal injury, and/or death.

Trigger Pull Force Adjustment:

WARNING! Changes from factory trigger settings may cause accidental discharge which may lead to property damage, serious personal injury and/or death.

Trigger adjustments may be made ONLY in the following circumstances:

  1. Competitive Target Shooters:
    1. The trigger assembly of the Model 700 Ultimate Muzzleloader rifles should only be adjusted for use by experienced and responsible shooters in a controlled target shooting environment where the rifle is never loaded with an ignition source except when it is in the ready-to-fire position with the muzzle pointed safely down range.
    2. If an ignition source is loaded onto the breech plug nipple and then not discharged, it should be immediately removed from the rifle.  NEVER move the rifle away from the down range position without first removing the ignition source from the rifle.

WARNING! Never carry an adjusted rifle with an ignition source in the loading port or on the bolt plug nipple.  Trigger pull on rifles used for hunting or for noncompetitive target shooting must never be adjusted.  Carrying an adjusted rifle with a live ignition source on the breech plug nipple may lead to property damage, personal injury and/or death.

  1. Firearm Sale or Transfer: If your rifle's trigger pull force (weight) has been adjusted and you intend to sell or otherwise transfer possession of your rifle, you must:
    1. warn the purchaser or recipient of your rifle that its trigger assembly has been adjusted, and
    2. give the purchaser or recipient the Owner's Manual for review and reference.

To Adjust Trigger Pull:

  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 raising the bolt handle.
  4. Pull the bolt fully rearward.
  5. 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 ignition source from the firearm.
  6. Ensure there is not a powder charge and projectile in the barrel 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.  See Picture A.
  7. Place the 1/16" hex key wrench provided into the trigger pull force adjustment socket in the trigger.  See Picture 10.

ml pic 10.PNG

  1. Adjust the trigger pull force to the desired setting by turning the adjustment screw:
    1. counter clockwise will decrease the trigger pull force.
    2. clockwise will increase the trigger pull force.
  2. Remove the hex key wrench.
  3. To ensure the adjustment is set, cycle the bolt and pull the trigger (dry fire) several times.
  4. Ensure the trigger pull force is correct by measuring the trigger pull force several times with a force gauge or deadweight following the manufactures instructions.

WARNING! If the proper trigger pull force is not maintained from trigger pull to trigger pull, then see "How to Obtain Parts and Service". Using a firearm with a trigger pull force which cannot be maintained may lead to property damage, personal injury, and/or death.

Note: The trigger force can be increased until the trigger will not move ar release the sear.

The Barrel:

WARNING! The inside of the barrel must be clean and free of any obstructions. Discharging the firearm with a dirty and/or obstructed barrel may cause property damage, personal injury, and/or death. See "The Ten Commandments of Firearm Safety" and the "Muzzleloading Safety Rules," in this manual.

To check the Barrel for Obstructions:

  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 raising the bolt handle.

  1. Ensure there is not an obstruction in the barrel 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 does not incorporate an obstruction.  See Picture A.

ml pic a.PNG

To Remove a Barrel Obstruction:

WARNING! NEVER try to remove an object from the barrel by loading another charge or ignition source and firing.  Discharging a firearm with an obstructed barrel may lead to property damage, personal injury and/or death.

  1. Always keep the firearm pointed in a safe direction.
  2. Remove the obstruction from the muzzle, see "To Remove a Charge and Projectile".
  3. If the obstruction cannot be removed from the muzzle as stated in step 2, remove the breech plug, see "To Remove the Breech Plug".
  4. Wash out the deactivate powder charge and residue.
  5. Insert a cleaning rod or ramrod from the muzzle until the obstruction is detected.
  6. Lightly tap the cleaning rod or ramrod against the obstruction to free the object from the barrel.
  7. Push the rod completely through the barrel until the rod can be seen at the ejection port.
  8. If an object cannot be easily pushed out of the barrel with a cleaning rod, return the firearm to a Remington Authorized Repair Center for repair.  See "Repair Services".
  9. Clean and lubricate the complete firearm.  See "Cleaning, Lubrication and Maintenance".

The Breech Plug:

The breech plug holds an ignition source known as a primer and maintains the chamber pressure within the barrel.  The Model 700 Ultimate Muzzleloader (ML) uses a special primer called Remington U.M.L. Ignition Source, which burns cleaner and reduces the overall cleaning effort.  Since the Model 700 Ultimate Muzzleloader is a clean burning system it is not required to remove the breech plug for normal maintenance.  The breech plug is located at the rear of the barrel in the receiver.  See Picture 11.

ml pic 11.PNG

To Remove the Breech Plug:

Do not remove the breech plug under normal conditions or maintenance.

WARNING! Never attempt to remove a breech plug with a primer attached to the breech plug.  Not following these instructions may lead to property damage, personal injury and/or death.
