About the i5 Gearbox While the traditional version 2 gearbox has for the most part remained unchanged since its inception, small changes have occurred over time, usually as the result of popular user modifications that were then made into factory available options. With input from players and vendors, G&P has released their newest iteration of the Version 2 Gearbox, the G&P i5. While internally similar to their tried and true V2 gearbox, the i5 comes from the factory with a plethora of upgraded components. The i5 is powered by an M140 motor and features 8mm bearings for more robust performance and reliability. The top-down QD spring guide makes spring changes far easier, requiring only the removal of the upper receiver and buffer tube screw. No gearbox disassembly required.

Also included is an inline MOSFET with electronic trigger and Electronic selector, eliminating sensitive trigger switches and selector plates. The i5 gearbox takes the traditional V2 gearbox and makes it more reliable and user friendly, without sacrificing the performance that players have come to expect from G&P.

"The gun itself feels solid, it's beatiful, and it feel so damn good in your hands, the end of the day it only gave me nightmares. I was so hyped up for the i5 gearbox only to be left extremely disappointed. I never even got the chance to fully use and utilize the gun because of the number of problems that keep happening. It was making this crunching sound whenever i fire, it misfeeds, and the trigger would sometimes lock, not to mention it drains your battery fast! I sent it back to evike for repairs in which they replaced the gearbox entirely, but after getting it back the gun just wouldn't work anymore and would only make this grinding high screeching sound that the gears would make. I'm sad to say this, but I would not recommend guns with the i5 gearbox in them. I have also ordered the GRY with the same i5 gearbox and also encountered the same similar problems until it a part of the piston chipped. I now have sent mine to a local airsoft tech for fixing. Totally not worth the price for this gun.

"Awesome gun so far, haven't been airsofting with it yet with it but the rate of fire is insane and it shoots great, this is my first AEG and i'm not disappointed so far. battery slot is a bit small, that is a valid complaint but im not worrying about it, I can get my 7.4 LiPo in without too much of an issue. Overall I would definitely recommend. One other thing is the dust cover wont shut but from what I've read G&P dust covers aren't meant to shut

"Great Gun But... Be careful

I got the gun, gun didnt work. Brought to my local shop, and wiring harness was broken. So thanks Evike for not testing the gun before shipping.

Any ways after it was working...

Gun is Great - First shots range from anything around 380 - 440 fps (.2g bbs). For some reason this gun likes to have the first shot when cronoing around 180fps. After that it is around 400 fps ish. Tight mag well, so I recommend G&P magazines or Valken. G&P Mags fill the Mag well and wont slip. Valken Mags will some times slip. I recommend all metal attachments it will make the gun feel more "Real" and heavy. For long days of fighting I recommend a sling. The mock silencer is more of a cover for the long barrel. So if you expected a shorter barrel you could cut it off.. but I dont recommend it because it will be great range. When I was playing with it for the first game I had longer range then most of the snipers at the game.

The bad, like before bad wiring harness, only thing I would make sure is the gun works first. Evike just needs to make sure to test before sending. 2 The weird FPS every once in while the weird 180-200fps for one or two shots then 400 fps. 3. Battery Compartment, its in the buffer tube with the wire. SO very small space for battery. SO recommend a small stick 7.4v with 20cc normal 40cc burst. It sticks out of the gun a bit but the stock covers up the part sticking out so it works.

Overall great gun, 4 out of 5 due to the harness issues and fps issues. Recommend attachments, Metal Grip, G&P Mags (Hi Cap), Eo Tech Sight, With Flip Magnification, 1 or 2 point sling and 7.4 small stick battery. 380-410 fps with .2 g bbs. about 365 - 375 fps with .25g bbs.
