1. Foreword We are pleased that you have chosen a FNH USA SCAR autoloading rifle. The SCAR combines the latest in autoloading rifle design, manufacture and testing methods to create a rifle worthy of the operators of the U.S. Military’s Special Operations Forces. The SCAR represents the highest levels of reliable function, consistent accuracy, comfortable ergonomics and the operating precision and safety expected from an FNH USA firearm. Unique and simple in design, the rifle is very easy to maintain.
. Firearm SAFETY INFORMATION your firearm’s muzzle in an unsafe direction. See Section 9 for instructions on the operation of this firearm’s “safety.” Failure to follow any of the following warnings could result in serious injury or death. Remember, safe gun handling does not stop with your firearm’s mechanical “safety” devices, it starts there. Always treat this firearm with the respect due a loaded, ready-to-fire firearm. As a firearm owner, you accept a set of demanding responsibilities.
Wear shooting glasses to protect your eyes from flying particles. Allow proper distance (eye relief) between a scope and your eye when firing a scoped rifle or shotgun. Do not use unorthodox shooting methods that could cause the rearward travel of the slide or bolt of a firearm to contact your eyes, face or hands. Always keep a safe distance between the muzzle of your firearm and any persons nearby, as muzzle blast, debris and ejecting shells could inflict serious injury.
If the primer is not indented, your firearm should be examined by a qualified gunsmith and the cause of the malfunction corrected before further use. Glance down the barrel to make sure that there are no obstructions in the barrel. If there is an obstruction, completely clear the barrel before loading and firing again. Failure to follow these instructions can cause extensive damage to your firearm and possible serious injury to yourself and others.
20 BE CERTAIN your firearm is UNLOADED BEFORE CLEANING. Because so many gun accidents occur when a firearm is being cleaned, special and extreme care should be taken to be sure your firearm is unloaded before disassembly, cleaning and reassembly. Keep ammunition away from the cleaning location. Never test the mechanical function of any firearm with live ammunition. 21 TEACH AND SUPERVISE FIREARMS SAFETY TO ALL MEMBERS OF YOUR FAMILY, ESPECIALLY TO CHILDREN AND NON-SHOOTERS.

5.2. Operation When the trigger is pulled, the firing pin strikes the primer of the cartridge, resulting in the rifle firing. Gases from the fired cartridge travel down the barrel with some diverted into the gas regulator. The gases impart energy onto the short stroke gas piston, pushing it to the rear. The gas piston contacts the front of the bolt carrier moving it to the rear. During the rearward movement of the bolt, the empty cartridge case is ejected out of the ejection port.

20.1. Cleaning Procedures Your SCAR 16S 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. Regular maintenance will also include cleaning the barrel and gas system.
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. Cleaning the Trigger module The trigger module has been adjusted at the factory to provide a short, crisp pull consistent with safety and reliability.
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.
3. Slide the moving parts assembly back into the receiver until the charging handle slot on the bolt carrier is aligned with the charging handle slot in the receiver frame. 4. Insert the charging handle into the left or right side of the receiver (Figure 45, page 45). (Generally into the left side for right-handed operators and into the right side for left-handed operators.) 5. Using the charging handle, slide the moving parts assembly all the way forward in the receiver.
5. Ensure the trigger module is fully seated to the rear before pushing the takedown pin to the left and securing the trigger module to the receiver assembly (Figure 52). FIGURE 52 Your firearm is now fully assembled. Immediately confirm that the “safety” selector is in the on safe position.
