The FNC (Belgian: Fabrique Nationale Carabine) is a 5.56×45mm NATO assault rifle developed by the Belgian arms manufacturer Fabrique Nationale de Herstal (FN Herstal) and introduced in the late 1970s.
The rifle was developed between 1975–1977 for NATO standardization trials. The rifle’s design is based on the FNC 76 prototype, which itself originated from the commercially unsuccessful FN CAL rifle. This prototype was soon withdrawn from the NATO competition after performing poorly due to its rushed development. Later trials for the Swedish Armed Forces held between 1981–1982 using updated prototypes proved the utility and efficiency of the design, impressing both the Swedish military and Belgian army staff back at home. The FNC was finally adopted by the armed forces of Belgium in 1989, as a service-wide replacement for the 7.62×51mm FN FAL after having been issued in small numbers to airborne infantry units for several years.
Indonesia purchased approximately 10,000 rifles in 1982 for its air force, and later acquired a license to manufacture these rifles for all branches of the armed forces. These are built by the Indonesian firm PT Pindad as the Pindad SS1 and Pindad SS2. A version of the FNC adapted for arctic conditions was adopted in 1986 as the standard service rifle of the Swedish Armed Forces (with the designation Ak 5) and is used in relatively small numbers by a number of other armies and police organizations.
The FNC is a selective fire weapon that uses a gas-driven piston operating system (with a long-stroke piston) and a rotary bolt locking mechanism equipped with two locking lugs that engage corresponding recesses in the barrel extension. The bolt is rotated and unlocked by the interaction of the bolt's cam pin with a camming guide contained in the bolt carrier. Overall, the mechanism strongly resembles the Kalashnikov, but adapted to more advanced design and production methods. The rear part of the cocking handle slot, cut in the upper receiver for the cocking handle, is covered by a spring-loaded cover which automatically opens by the handle when it goes back and automatically closes the opening when the cocking handle returns forward. 
The spring extractor is located inside the bolt head, the ejector is fixed and riveted to the inside of the receiver housing. The FNC uses a 2-position gas valve, a hammer-type firing mechanism and a trigger with a fire selector switch that is simultaneously the manual safety, securing the weapon from accidental firing. The selector lever is located on the left side of the receiver and has 4 settings: "S" - weapon safe, "1" - single fire mode, "3" - 3-round burst, "A" - continuous (automatic) fire.
The FNC's barrel features a flash suppressor that is also used to launch rifle grenades (only the standard rifle model has this capability). The gas block contains a gas valve setting that is used to isolate the gas system, providing an increased volume of propellant required to fire a rifle grenade. The sheet-metal gas valve switch when pulled upright, acts as a V-notch sight used for aiming the rifle grenades. The piston head and extension, as well as the gas port block, barrel bore and chamber, are hard-chrome plated to minimize the effects of propellant fouling.
The rifle feeds from 30-round steel magazines that are interchangeable with magazines from the American M16 rifle (STANAG 4179 system). After the last round is fired, the bolt will remain closed as there is no provision for an automatic bolt hold open. However, the bolt handle can be manually worked to hold the bolt back. FNC magazines will function in M-16/AR-15 type rifles but the follower will not hold the bolt open on the last round unless they have been replaced by an M-16 type follower.
The plastic-coated, lightweight alloy skeleton stock folds to the right side of the receiver. A fixed synthetic (polyamide) buttstock is also available.
The rifle has a flip-type L-shaped windage-adjustable rear sight with two apertures with settings for 250 and 400 m, while the front sight post is adjustable for elevation. Optics such as the Hensoldt 4X telescopic sight can be attached with the use of a receiver-mounted adapter.
Standard equipment supplied with the FNC includes a spike bayonet or a variant of the American M7 blade bayonet (with the use of a lug adapter) and a sling. The rifle can be deployed with a barrel mounted bipod and blank-firing adapter.
The FNC is produced in two primary configurations: a standard rifle and short (carbine) length. The "Standard" Model 2000 rifle and the "Short" Model 7000 carbine are equipped with barrels with 6 right-hand grooves and a 178 mm (1:7 in) rifling twist rate used to stabilize the longer and heavier Belgian SS109 bullet. The Model 0000 rifle and Model 6000 carbine use a slower 305 mm (1:12 in) twist rate for the shorter and lighter American M193 bullet.
Fabrique Nationale also offers semi-automatic-only Law Enforcement carbine versions: the Model 7030 with a 178 mm (1:7 in) rifling twist and the Model 6040 with a 305 mm (1:12 in) twist rate. These single-fire carbines feature a 410 mm (16.1 in) barrel and are also capable of firing rifle grenades and mounting a bayonet.
The Swedish service rifle built by Bofors Ordnance (currently BAE Systems Bofors) is a modernized Model 2000 rifle without the 3-round burst fire control setting. It was accepted into service in 1986 as the Ak 5 after extensive trials and receiving several modifications and replaced the 7.62mm Ak 4 (a licensed copy of the Heckler & Koch G3). Bofors has produced several variants of the basic Ak 5: the Ak 5B (equipped with a British 4x SUSAT optical sight but no mechanical iron sights), the Ak 5C (a modular variant designed for compatibility with various accessories), and the Ak 5D (a compact variant for vehicle crews).
In Indonesia, a modified version of the FNC is produced under license as the Pindad SS1, with adaptations for jungle climate conditions, is used as the standard assault rifle of the Indonesian armed forces. The Pindad SS2 is an updated version of the Pindad SS1. Since 2006 the SS2 assault rifles are being pressed into service in the Indonesian military and police in order to gradually replace the SS1 assault rifles that are in service from the 1990s.
