"Out of the box, I am quiet pleased with the product.
Now, I bought this with the intention of using it in an A&K Masada/ACR.
This gear box is completely compatible and allows for the use of Selector gear and Axle. The Top has been milled down as well so you can run wires over the box if you intend too. There are only a few things you need to keep in mind. The 8mm shims will require a modification to the selector plate, or the right M4 plate to be purchased.
There is a small tang on to top of the box where the seems meet that may need to be filed down however, it does, in no way this compromise the box.
The extra spring powered slide catch arm will have to be removed, however this also doesn't hinder the boxes use in the A&K Masada/ACR.
It's well manufactured, and provides support internally for gears. So that they don't collide with each other which is excellent in High speed and torque applications. An Excellent Buy, that has a fair price, and IMO should be worth more!

"This is a good gearbox especially for the price. You get the gearbox,spring guide, screws, 8mm steel bushings.
i bought this gearbox for my "SR-47 Guardian edition" (custom made). it is the best gearbox super easy to work just don't do what i did the first couple times. (forgot to put the spring in).
i feel this gearbox is pretty durable and will last me quite some time. their are also no proprietary parts like the older models.

"First, I'll start with the good.
I received the gearbox and had a good first impression. It appears to be well made, and the spring guide is made from a durable polymer plastic. A large hex key (of size I have yet to determine) is needed to actually take out the spring guide. I plan on using it to easily switch between an m110 and an m120 for indoor and outdoor games, respectively. I'm modifying my m4 to allow the spring guide to be taken apart with only the stock off, instead of taking the entire gearbox apart. If you are afraid of modifying your gun's externals and cannot easily get to the back of the gearbox with enough room to get the spring guide out, I cannot recommend this to you.
Now the bad,
the gearbox appears to be constructed out of some pot metal. I would use it for setups pulling an m120, but I wouldn't use it to pull much more. The spring guide is made of a durable polymer plastic and there aren't any metal replacements on evike. While the gearbox is compatible with standard spring guides, the quick change spring guide is the real purpose for buying this gearbox. My SHS 13:1 gears were a little too large for the gearbox, but it wasn't anything a dremel couldn't fix.
Summary,
good gearbox for lower torque setups (m120 and lower). Some modification may be required. I only recommend this to people who have guns that have easy access to the back of the gearbox (ie, mp5) or are willing to modify their gun.
