Extremely compact and lightweight, from afar the ARP556 resembles a traditional M4 type rifle, but when one gets closer, they realize the ARP556 is a completely different beast. Based off of the G&G CM16 series of AEGs the ARP566 retains all of the features favored by players but in a SBR form. Using the traditionally solid G&G gearbox, paired with their inline MOSFET, the ARP556 puts out all of the same performance of a CM16 M4, but in a compact and unique package.
