Parts of the Firearm

Overview

Learn the important components of your Bolt Action Model 770 firearm.

Congratulations on your choice of a Remington®. With proper care, it should give you many years of dependable use and enjoyment. For best results, we recommend that you use Remington Ammunition - the ammunition used in factory testing your firearm against our rigorous function and performance standards.

General Operation

All Remington® centerfire bolt actuated rifles operate the same. The firearm is capable of firing multiple shots after each pull of the trigger and cycle of the bolt. At the start of the firing cycle after the trigger has been pulled, a cartridge has be discharged, and the safety engaged; the action is unlocked and the firing pin is cocked by rotating the bolt handle upward. As the bolt moves rearward, the spent cartridge case is pulled from the chamber. When the spent cartridge clears the chamber the cartridge is expelled from the firearm through the ejection port. As the bolt moves forward a new cartridge is stripped from the magazine and is placed into the chamber. The cycle is completed by rotating the bolt fully downward, locking the bolt and cartridge into the firing position.

Important Parts of the Firearm

Serial Number and Cartridge Designation

The serial number is located on the shooter’s left side of the receiver. See Picture 2.

Specifications for the correct caliber and cartridge intended for use in your firearm is located on the shooter’s left side of the barrel. See Picture 3

WARNING! Only use the specified cartridge type and caliber of ammunition specified for your firearm as designated on the barrel. See To Load Your Firearm.

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 lifts the sear and 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.

04770parts.png

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

When you are ready to FIRE 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. See Picture 5.

05770parts.png

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

WARNING! The firearm will fire when the trigger is pulled and the safety mechanism is OFF or in the "F” or “FIRE" position.

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

WARNING! Do not alter, modify, bypass, or render the safety features inoperative.

The Locking Device

This firearm was originally sold with a key-operated locking device or an integrated security system (ISS) 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.

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 with your firearm, which should be kept unloaded and locked in a safe place.

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

The Integrated Security System

Some 710™ Models are equipped with an integrated security system (ISS). When activated the bolt can not be closed in the firing position.

The ISS is located on the left side of the bolt assembly in the bolt plug. See Picture 6.

The “J” shaped slot is the key hole for engaging and disengaging the security system. The red and white indicator dots indicates whether the security system is disengaged (Red) or  engaged (White). View the indicator dots from the top of the bolt assembly.

To Engage the Integrated Security System

  1. Always keep the firearm pointed in a safe direction.
  2. Verify the firearm is unload. See instructions How to Unload the Firearm.
  3. The bolt must be installed in the firearm before engaging the Integrated Security System. See instructions To Install the Bolt Assembly.
  4. Slide the bolt half way in the receiver.
    WARNING! Do not attempt to engage the Integrated Security System when the bolt is closed and locked in the firing position.
  5. Push the key fully into the “J” slot.
  6. Turn the key clockwise until it stops and white indicator (engaged) dot is visible.
  7. Remove the key by pulling it outward. The system is now engaged. The bolt CANNOT be locked into the firing position.

To Disengage the Integrated Security System (ISS)

  1. Always keep the firearm pointed in a safe direction.
  2. With the white indicator dot visible, insert key until it stops.
  3. Disengage the system by turning the key counter-clockwise until it stops and the red indicator (disengaged) dot is visible.
  4. Remove the key by pulling outward. The system is now disengaged. The bolt assembly CAN be locked in the firing position.

While operating the integrated security system, NEVER use excessive force to turn the key. If the key will not turn freely, contact a Remington® Authorized Repair Center.

If you lose the key, DO NOT attempt to disengage the security system using a foreign object. This will damage your firearm. Contact your Remington Authorized Repair Center for a
replacement key. See Getting Parts and Service instructions to locate the nearest Authorized Repair Center.
