Your opponents will be gobsmacked by the ARP 556—that is, if you slow down long enough for them to see it. This upgraded version of the ARP 9 may have a full-metal construction, but it's still one of the fastest and lightest SMGs on the market. Instead of a 9mm magazine, the 556 takes a higher capacity M4/M16 style magazine. The unique frame design features a short M-LOK handguard and compact PDW stock. A pre-installed MOSFET allows for a programmable 3-round burst. The short barrel and crown amplifier ensure that everyone on the battlefield will hear you, even if you move too fast to be seen.

Pro tip:
High-capacity magazines have a reservoir that stores BBs and a wheel that must be hand spun to create pressure and feed rounds into the gun. As the BBs are fired, the pressure is slowly decreased until the magazine must be rewound.
