The G&G GK5CGL AEG (AK5C) is based on the Swedish take of a FNC. This rifle is definitely unique in design and is still fairly comfortable to carry. The rifle has an interesting take on an expanding stock that is fairly intuitive. The sights are very easy to acquire and ,even though the gun has a unique shape and feel, it remains easy to maneuver. One of the best things about this rifle is its compatibility with normal M4 mags.
