DFX TECHNOLOGY
FNC
Development of the Belgian Fabrique Nationale Carbine assault rifle for the 5.56mm NATO cartridge began in the early 1970s. The final design was produced circa 1978 and was consequently adopted by the Belgian Armed forces. 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. The long stroke gas piston is located above the barrel and is linked to the bolt carrier.

The main control of the FNC consists of the 4-position safety / mode selector switch on the left side of the receiver. Available modes are Safe, Single shot, 3-rounds bursts and Full automatic fire. The cocking handle is attached to the bolt carrier at the right side and does reciprocate with the bolt group when gun is fired. The rear part of the cocking handle slot, cut in the upper receiver for cocking handle, is covered by the spring-loaded cover which automatically opens by the handle when it goes back and automatically closes the opening when cocking handle returns forward.
