FNC is equipped with hooded post front sight and a flip-up,'L' shaped rear diopter sight with 2 settings, for 250 and 400 metersrange.

Barrel of the FNC is equipped with flash hider which also served as a rifle grenade launcher. Upper receiver is made from stamped steel, the lower receiver, along with magazine housing, is made from aluminum alloy. The receiver could be opened for disassembly and maintenance byremoving the rear pin, so the parts could be hinged around the forward pin (which also can be removed to separate receiver parts). The receiver is made from two parts that are linked by two cross-pins. The now common rotating bolt has two massive lugs that locks into the barrel extension. Both gas cutoff and grenade sight are located on the gas chamber, just behind the front sight. When grenade sights are raised intothe ready position, the gas cutoff automatically blocks the gas supply to the action, allowing for safe launching of rifle grenades. The gas system featured two-positions gas regulator (for normal or adverse conditions) and a separate gas cutoff, combined with folding rifle grenade sights. Unlike the AK-47, the gas piston rod could be separated from the bolt carrier when gun is disassembled. The long stroke gas piston is located above the barrel and is linked to the bolt carrier. The gas drive and rotating bolt of FNC strongly resembles the AK-47 system, but adapted for more advanced production technologies such as CNC machining and with some modifications. Although the FNC looks like it's FAL predeccesor, it's actually a AK/AR hybrid more than a FAL. The FNC also was sold to some police forces around the world, and, in limited numbers for civilians - as a'Sporter' model, limited to semi-automatic mode only. Swedish version is known as Bofors AK-5 and Indonesian version is known as Pindad SS1. Both nations did so under licenses and built their own modified FNC carbines at their own facilities. Sweden purchased the rifle in 1986 and Indonesia purchased the rifle in 1982. Known as the FNC 76, the final design, known as the FNC (Fabrique Nationale Carbine) was produced in 1978 and was adopted by the Belgian Armed forces in 1989. To fix their CAL booboo, Fabrique Nationale began to develop the new assault rifle for 5.56mm NATO cartridge in the early 1970s. Most of these rifles were sold in Latin America and Africa. Chambered in 5.56 NATO and designed with extensive use of steel stampings and plastics, 12,000 units of the CAL rifles were manufactured before FN closed the CAL production line in 1977 due to over complicated manufacturing and poor reliability.

In 1967 FN tried to produce it's first assault rifle, the FN CAL ('Carabine Automatique LГ©gГЁre', or Light Automatic Carbine). FN Fal/l1a1 - To fully appreciate what IMBEL accompliced in Brazil with the MD2 model rifle we need to go back to some of it's predecessors from Fabrique Nationale.
