GM Tático gives his take on the compact G&G Armament ARP9 3.0. The G&G ARP9 3.0 is a small and light AEG that mimics the M4/AR15 style and is ideal for close combat and speedsofting. It has a 4-inch rail with a hand stop, a foldable stock with built-in wiring, and a 14mm CCW threaded barrel for different muzzle options.
