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.

"Did not like how you have to take the stock off the buffer tube to put in the battery and you can not close the dust cover/bolt.
It did not come with the pistol grip and magazine shown, they are just standard M4 pistol grip and magazine.

The internals are amazing though as well as metal barrel, handguard, and recievers. Nothing wobbles either. The orange flash hider was easy to remove, which was awesome. Love the gun

"Worth the wait is all the needs said, super short trigger pull with great response, out of box range and accuracy is beautiful. Only complaint is the stock, im not a huge fan of needing to take the stick completely off of a buffer tube to put a battery in but thats an easy fix. Good job EMG on this one, will update after field use but as if roght now its and awesome rifle!

"-Gearbox 10/10: literally the best stock gearbox on the market (the main reason I bought the gun)

-Externals 9/10: (they didn’t include the motor grip and mag as displayed in the picture) it only states that the optic isn’t included. Everything else about the externals is outstanding.

-Hop-up & Barrel 5/10: had a lot of feeding & compression issues mainly with PTS mags but others as well (only ones that seemed to work with it were KWA mags) when the hop up didn’t have issues the bbs were never consistent at 50+ ft probably because it’s a cheap brass barrel **If you’re going to splurge the money on this gun you should go ahead and buy high quality aftermarket hop up and barrel assemblies**

Side notes:
-Make sure you do some research into the I5 gearbox before you buy this gun as it may be high maintenance for some.
-it only takes 1 kind of battery: 11.1v LiPo with deans connections (unless you’re tech savvy but idk why you would want to switch To something else lol)
-fps was at avg. 366 with .2’s (doesn’t mean yours will be the same) but if so you’ll have room to get some compression upgrades like getting a better hop up and barrel
-outer barrel threads aren’t the most durable out there so be careful when switching anything out on it.
-some people said the cerakote was terrible and scratched easily. They may have gotten a bad coating as I’ve accidentally bullied my gun already and haven’t gotten any scratching.

*from looking at others reviews, this product doesn’t seem to be that consistent in stock quality so when buying you may have issues that I didn’t mention or you may not have anything wrong with it.
