REX AKB-15 assault rifle was developed by Slovenian company AREX. First displayed in 2015, by mid-2018 it is reported to be in low rate initial production.
REX AKB-15 assault rifle is based on the Serbian (ex-Yugoslavian) Zastava M70 assault rifle, which, in turn, is a clone of the Soviet Kalashnikov AKM rifle. AKB-15 uses same receiver and internals (bolt group, trigger group, safety/selector) as its parent weapon. Key modifications include changes to the front and rear trunnions of the receiver and the all-new top cover, machined from aluminum alloy. Top cover extends forward almost up to the gas block, and at the rear end contains a separate backplate to which a buttstock is attached. Top cover connects to the receiver via three cross-pins, one above the barrel breech and two more at the rear of the receiver. To remove top cover, one has to pull all three pins out and then raise the cover with attached shoulder stock off the receiver. Rest of the disassembly is carried out more or less similar to any other Kalashnikov AK-type rifle. Side-folding shoulder stock is made from plastic and is adjustable for length of pull.
