G&G ARP9 3.0 Compact Airsoft AEG Rifle
(Model: 4.5" Polymer RIS)

"Great gun! I got the metal version so it is wired to deans. It has a very springy sound when you shoot it but it’s normal. Putting a Perun in it was tough but it’s in there. I would highly recommend an upgraded mosfet as the current one can burn out on an 11.1.

"Great gun if you plan to leave it stock. 5/5
Major headache if you want to upgrade it. 3/5

PROS: great size, pretty good trigger response, folding stock is very innovative, the mag it comes with feeds well and is a major upgrade from previous versions. Comes with an electronic trigger and a mosfet from the factory that pair very well together.

CONS: The new mags are nice but the way they’re designed means there will always be 8-10 BBs left that won’t feed. The polymer version is wired as a tamiya connector. The battery compartment is very small. 1000 MAH is all you’ll be able to fit unless you plan on 3D printing an extended buttpad. As a previous reviewer mentioned, this gun sounds very “springy” (you can feel and hear the mainspring in the gearbox).

Speaking of the gearbox, it says it’s a V2 gearbox… but it’s G&G’s “upgraded M.I.G.” The gearbox shell is not like a standard V2 and makes routing wires a pain when you switch the ETU to a PERUN Hybrid unit (which I highly recommend). When and if you do switch to a perun, you have to cut the wires that run to the battery because of the folding stock connectors. Or you have to change the folding stock to something else.

UPGRADES: If you want up upgrade throw in the Perun Hybrid. The benefits of it are well worth the cost, but to get it to work with this you’ll have to know how to solder. As mentioned earlier, the battery connector is tamiya so I’d recommend switching to deans for size in the limited battery compartment and the increased performance and run an 11.1 lipo. Keep the stock hop up unit, but go for a tight bore barrel and new bucking. I tried throwing in a 35k motor with stock gearing but it kept blowing the 25amp fuse. (You could put in a higher amp fuse but then your battery becomes the fuse *very bad idea*)

Keep the same cylinder, go with the Kratos piston and whatever head you want to. The stock nozzle is polymer so go with the MAXX double O-ring nozzle made of metal. I tried 13:1 gears by EMG but the stock gearing is completely adequate.

With the upgrades I did I get 12 rps on semi, and 22 rps on full auto. I run exclusively .25 gram BBs and my FPS never leaves the 300-302 fps range.

If I could do this build again, I’d pull the entire gearbox and use it for a different gun and just HPA this one with a standard V2.

Hope this helps,

"My battery has to be oriented correctly and I have to rotate it 30million times to get it to shoot. But once it shoots it shoots gooooooooood. No idea why the wire connection is funny like that.
