G&G CM16 ARP 556 AEG If you are looking for a new unique primary then look no further, G&G has got you covered! The G&G CM16 ARP 556 airsoft gun utilizes its polymer construction and compact form to make it light to carry while remaining tough through rigid conditions just like the ARP 9 but with a traditional M4 Magazine. Toward the rear you will notice that G&G has installed a retractable PDW style stock that can fit a 11.1v LiPo battery. On the front rests a 5" Milspec M-lok rail with areas to attach rail segments to install the accessories needed to optimize your airsoft gun to its maximum potential. Across the top section is a monolithic standard rail system that provides plenty of space for an optic and the included flip up sights.
