CERTAIN IT IS UNLOADED. Never point any firearm at anything you do not intend to shoot. Be extremely alert and aware of all persons and property within the range of your ammunition. 2 NEVER RELY TOTALLY ON YOUR FIREARM’S MECHANICAL SAFETY DEVICES. LIKE ANY MECHANICAL DEVICE, A SAFETY CAN SOMETIMES FAIL; IT CAN BE JARRED OR INADVERTENTLY MANIPULATED INTO AN UNSAFE CONDITION.
MAGAZINE TO MAKE CERTAIN THAT THE FIREARM IS COMPLETELY UNLOADED. Make certain the firearm does not inadvertently contain any ammunition. Always keep the chamber empty and the safety in the on safe position unless shooting is imminent. If your firearm is equipped with a detachable magazine, be aware that removing the magazine does not mean your firearm is completely unloaded, a cartridge could be in the chamber.
6 DROPPING OR JARRING A LOADED FIREARM CAN CAUSE AN ACCIDENTAL DISCHARGE. This can occur even with the safety in the on safe position or the hammer in the decocked position. Be extremely careful while hunting or during any shooting activity, to avoid dropping any firearm. 7 SHOOTING FROM ELEVATED SURFACES IS DANGEROUS. Doing so may increase the risk of mishandling a firearm. The following rules should always be observed. Always make certain that the surface being used is safe and stable.
Completely unload the firearm as described in Section 15. After assuring yourself that the firearm is completely unloaded, look through the barrel to be sure it is clear of obstructions. If an obstruction is seen, no matter how small it may be, clean the bore with a cleaning rod and patch as described in Sections 20 of this owner’s manual. 10 BE ALERT TO THE SIGNS OF AMMUNITION MALFUNCTION. IF YOU DETECT AN OFF SOUND OR LIGHT RECOIL WHEN A CARTRIDGE IS FIRED, DO NOT LOAD ANOTHER CARTRIDGE INTO THE CHAMBER.

DO NOT USE HANDLOADED, RELOADED OR STEEL-CASED AMMUNITION. The barrel and action of this rifle have been made with substantial safety margins over the pressures developed by established U.S. commercial loads.
18 ALWAYS UNLOAD YOUR FIREARM’S CHAMBER BEFORE CROSSING A FENCE, CLIMBING A TREE, JUMPING A DITCH OR NEGOTIATING OTHER OBSTACLES. Never place your firearm on or against a fence, tree, car or other similar object. For law enforcement and military personnel, refer to the procedures of your department. 19 BE DEFENSIVE AND ON GUARD AGAINST UNSAFE GUN HANDLING AROUND YOU AND OTHERS. Don’t be timid when it comes to gun safety.

5.1. DESCRIPTION The FN SCAR is a gas-operated, semi-automatic repeating rifle. SCAR rifles are a direct result of the U.S. Military’s search for a modular battle rifle that is easy to use and extremely reliable. SCAR rifles have been developed using the latest computer software, extensive materials testing, real-world research and end user assessments from special operations forces operators. This information has culminated in the next generation of technologically-advanced rifles.
to the rear; the trigger is downward or underneath; the barrel is upward or on top. For general parts nomenclature, refer to Figures 1 and 2. 7. SERIAL NUMBER The serial number is located on the left side of the receiver, just below the upper rail. Record the serial number at the front of this owner’s manual for future reference. 8.
FIGURE 3 FIGURE 4 Safety shown in the on safe position. Safety selector in the fire position SCAR rifles utilize an ambidextrous safety selector located on the trigger module just rearward and above the trigger. This location allows the safety selector to be easily manipulated with the thumb of the firing hand. With the safety selector in the “S” position, the rifle is in the “on safe” position, and rearward movement of the trigger is completely blocked (Figure 3).

FAILURE TO FOLLOW THESE WARNINGS COULD RESULT IN SERIOUS INJURY OR DEATH. 10.1. BOLT RELEASE FUNCTION The bolt release is located on the left side of the rifle, just above the magazine release (Figure 5). It automatically engages after the last cartridge in the magazine has been fired and locks the bolt to the rearmost, open position.
DO NOT USE AMMUNITION OTHER THAN WHAT IS DESIGNED FOR USE IN YOUR SCAR RIFLE. EXAMINE EVERY CARTRIDGE YOU PUT IN YOUR FIREARM. DISCHARGING FIREARMS IN POORLY VENTILATED AREAS, CLEANING FIREARMS OR HANDLING AMMUNITION MAY RESULT IN EXPOSURE TO LEAD AND OTHER SUBSTANCES KNOWN TO CAUSE BIRTH DEFECTS, REPRODUCTIVE HARM AND OTHER SERIOUS PHYSICAL INJURY. HAVE ADEQUATE VENTILATION AT ALL TIMES. WASH HANDS THOROUGHLY AFTER HANDLING AMMUNITION.
However, some jurisdictions limit the magazine capacity to 10 cartridges. All SCAR rifles sold in those jurisdictions will be shipped with limited capacity magazines in compliance with local or state law. Make sure you have verified the capacity of your magazine before loading it in your rifle. 13. LOADING WHEN LOADING YOUR RIFLE ALWAYS KEEP THE MUZZLE POINTED IN A SAFE DIRECTION, ALWAYS PLACE THE SAFETY SELECTOR IN THE ON SAFE POSITION AND KEEP YOUR FINGERS AWAY FROM THE TRIGGER.

WITH LIVE AMMUNITION. FAILURE TO FOLLOW THESE WARNINGS COULD RESULT IN SERIOUS INJURY OR DEATH. 20.1. CLEANING PROCEDURES Your SCAR 16S/17S will function better, more reliably and be more accurate over a longer period of time if it is properly maintained and kept clean. Clean your firearm after every day of shooting, and more often if it becomes excessively dirty during your shooting session. A minimum cleaning includes wiping down the firearm and lubricating key parts.
NOTICE! DO NOT USE A STAINLESS STEEL BRUSH TO CLEAN THE BORE. IT COULD DAMAGE THE CHROME PLATING. If necessary, clean the chamber and locking lugs using a Mil-Standard M16 style chamber brush. Properly apply military-grade cleaner/ lubricant to the brush and insert it into the chamber. Rotate the brush in a clockwise direction several times and remove. 4. After all fouling has been removed, the chamber and bore should be wiped dry.
regulator to ensure they are free of debris and carbon build-up. If the ports are fouled, it may be necessary to use a dental pic to remove carbon build up (Figure 39). 10. Wipe all exposed metal surfaces with a lightly oiled cloth making certain that all finger marks are removed. Finger marks provide a place where moisture can accumulate. The metal of the firearm should receive a light film of oil any time it has been exposed to weather or handling. 20.2.
5. Perform any cleaning of the parts and receiver cavity as necessary. We suggest cleaning the trigger group with a polymer-safe aerosol gun cleaner. Allow it to dry and then very lightly lubricate the trigger and hammer contact points. NOTICE! DO NOT USE TOO MUCH LUBRICANT. EXCESSIVE LUBRICATION COULD INTERFERE WITH THE FUNCTION OF YOUR RIFLE. 20.3.
FIGURE 40 Incorrect FIGURE 41 Correct Ensure the gas rings are not aligned as shown in the photo on the left. Install the gas regulator by turning counterclockwise to the 12 o’clock position. 1. Ensure that the notches in the gas rings of the piston are not aligned (Figure 40). 2. Insert the gas piston into the gas block with the gas rings towards the muzzle. 3.
NOTICE! DO NOT USE EXTREME FORCE ON THE FIRING PIN RETAINING PIN, IT IS NOT DESIGNED TO FIT FLUSH INTO THE BOLT CARRIER. APPLYING EXTREME FORCE TO THE FIRING PIN RETAINING PIN COULD RESULT IN PERMANENT DAMAGE. 21.3. INSTALLATION OF THE MOVING PARTS ASSEMBLY 1.
