FN SCAR is an assault rifle manufactured by FN Herstal in Belgium. The standard issue rifle comes in NATO 5.56 mm caliber. The rifle is specially designed for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. In fact, SCAR is short for Special Operations Forces Combat Assualt Rifle.

Introduction

In 2009, a SOCOM launched a new assault rifle for special forces to replace the old M4 carabine. All main arms manufacturers shipped their assault rifles to SOCOM for testings. Among them, one rifle was from Belgium company FN Herstal. SCAR-L CQC is a version for close combat with shortened barrel. CQC is an abbreviation for Close Quarter Combat.

This family of rifles consists of two main types. The SCAR-L, for “light,” is chambered in 5.56×45mm NATO cartridge, and the SCAR-H, for “heavy,” is chambered in 7.62×51mm NATO. Both are available in Close Quarters Combat (CQC), Standard (STD), and Long Barrel (LB) variants.

Design

The Special Operations Forces Combat Assault Rifle (SCAR) is a modular assault rifle family designed by FN Herstal (FNH) responding to US special Operations Command requirements. FN won US Special Operations Command (SOCOM) development contract in November 2004. The SCAR family of weapons includes the SCAR Heavy 7.62mm rifle, SCAR L (Light) 5.56 mm version, and Enhanced Grenade Launcher (EGLM) grenade launcher, which will be able to fire Fuse Programmable Ammunition.

This rifle is fully made for the needs of special forces; it is accurate, compact, and lightweight. Many parts of the SCAR rifle are fully adjustable for the operator’s needs, whether left or right-handed. There are also few Picatinny rails mounted on a rifle, and there is enough room to mount many gadgets like red dot sights, laser sights, and other additional equipment.

SOCOM testings

This rifle got the best scores in SOCOM testings and proved itself like a perfect assault rifle. SCAR-L CQC has moderate recoil and has two modes of fire, single shot, and full-auto. When firing in the single-shot mode, you can feel how good the SCAR rifle is.

SOCOM made few criteria for testings. The first one is accuracy in both single and full auto mode. We engaged target from 50 meters for single-mode, and from ten shots, we got 95/100 with mechanical sight on target with 10 points diameter of 5 cm. For full autotest, we engaged a target from 20 meters and got a solid result. Nine were targets creating a score of 57/100 what appears as solid results for burst fire from ten shots.

The second criteria were the overall length and height of the weapon and using it in urban combat or houses, buildings, and other places with so much space. SCAR-L CQC is almost ideal for this part of the job. It’s good in urban terrains, almost like in open areas—a really compact assault rifle.

The third criterion was SCAR reliability. It’s stone-cold reliable. Elegant, robust, and clean-running design should give a very long service life.

Initial production

The FN SCAR system completed low rate initial production testing in June 2007. After some delays, the first rifles began being issued to operational units in April 2009. A battalion of the U.S. 75th Ranger Regiment was the first large unit deployed into combat with 600 rifles in 2009. The U.S. Special Operations Command later canceled their purchase of the SCAR-L and planned to remove the rifle from their inventory by 2013. However, they will continue to purchase the SCAR-H version and plan to purchase 5.56 mm conversion kits for the SCAR-H, allowing it to substitute for the SCAR-L.

Can SCAR rifles replace the M4 series?

They could and would have advantages over the M16 family of rifles, but it may not be worth the advantages. In theory, yes. If the SCAR-L became the standard infantry rifle of the USA, it might help even more with standardization across the board. The US military already uses the SCAR-H, and Special Ops uses the SCAR-L at times.

I would personally prefer a SCAR-H, but honestly, the SCAR-L looks way more awesome than the M4 and would really intimidate the enemy a bit more. Also, since at range, it would be more difficult to tell who has a .308 and who has a 5.56mm, enemy snipers/sharpshooters would have a more difficult time distinguishing targets by sight and would have to wait for them to fire, slowing down the rate at which soldiers are taken out.

Is that a greater advantage than how cheap you can get an M4 series rifle? Maybe, maybe not. Keep in mind you can get a decent AR-15 (not necessarily a Colt mind you, I think one of those or an Armalite or Bushmaster will run you $1000, but a decent one) for about $600 brand new(there was a time you could build one for that price. Now it’s crazy cheap to build one out.) High demand, high popularity, high supply. This led to cheaper processes to making the guns and, therefore, lower prices for them. A SCAR-L will run you about $1500 in comparison, and the SCAR-H will run about $3000, compared to $1500 for an M1A/M14-style rifle. Prices are from the civilian side as the military is likely paying about 10x more than they should for weapons anyway.

Also, there’s an accuracy issue after it starts heating up from shooting. Any “not an AR” 5.56 on the civilian side starts stringing shots pretty bad as they heat up. Even the SCAR-L has that problem. However, the SCAR rifles are actually decent at minimizing that, it seems, so it keeps up with the M16/4. I don’t think military versions are too heavily different, though they may do it faster because of the full-auto fire if that’s needed to get out of a situation.
