This updated ARP 9 is equipped with a longer 7" full aluminum M-LOK rail and detachable handstop. The iconic polymer receiver keeps the overall weight down. The new GOS-V9 minimalist retractable PDW-style stock gives you more space to fit your battery to reduce the need for a battery extension unit. In addition, we have increased the standard magazine capacity from the standard 60-round magazine on the original ARP 9 to a new larger capacity of a 170-round magazine with the ARP 2.0.
Internally, a longer 168mm inner barrel is installed as compared to the original 128mm length of the ARP 9. The polymer rotary-up improves consistency when adjusting your hop-up unit. As for the brains, an improved electronic trigger unit (E.T.U.) and the newest Gen 4. MOSFET is installed for crisp trigger pulls and enhanced battery protection.
