Golgy A Sunday gamer gives his thoughts after going over the G&G ARP9 2.0, the popular PCC AEG from the Taiwan-based airsoft manufacturer. The updated ARP 9 features a longer 7" full aluminum M-LOK rail and detachable handstop, a new GOS-V9 minimalist retractable PDW-style stock, a 170-round magazine, and a longer 168mm inner barrel. Internally, it has an improved electronic trigger unit (E.T.U.) and the newest Gen 4. MOSFET. These upgrades make the ARP 9 more versatile, powerful, and durable.
