Hello! I’m selling a very nice custom built arp9. This gun was purchased about 3 mouths ago and has never been Fielded it has only been tested. It has a Pts grip and a key-mod rail and 2 mid cap mags and 2 hi cap mags. The internals are as follows: - gate ASTER - Laylax Prometheus 13:1 gears - Prometheus spring - Prometheus Tappet plate - Full Metal Gearbox Shell and Hardware This is a great option for a really nice cqb gun. It shoots at about 325 FPS and the rps is kinda low but if you put in a new high speed motor you can get up to 40 rps! I am ask just about 550 obo. I am not looking to trade and I am willing to ship. I payed about 750 for the gun and upgrades and thats without the mags. HMU with any questions I am happy to help!
