"So, as I've owned a GBB-Enabled G36 for nearly a year by this point, I figured it would be prudent to write a review.

For some context: My local field, roughly a year and a half ago, began to sell off their long-obsolete rental guns, which for reasons I have never understood were Umarex-Ares G36KVs. I snapped one up for the low low price of $100, and promptly discovered that the gearbox was in the process of ripping itself apart. Those things are built strong, but not that strong. So, I found myself at a crossroads. I could attempt to find a replacement gearbox (which is expensive) or I could purchase this kit, which is less so. I chose this kit.

I was not disappointed. Unlike the other reviewers, after I removed all the AEG-Bits, I required absolutely no modifications to install the kit. It really lived up to its Drop-In nature, for me at least. I had it installed within an hour of receiving the package, and after firing a couple mags I was stunned. It kicks hard, so much so that it would likely throw off the zero on a lot of lower-end sights, and it is very accurate and efficient considering what I can only assume to be a weirdo hop-up.

As for the Pros:
Kicks hard
Shoots hard (I've experienced some variance, but mostly in the 350-390 range)
Accurate (I haven't tested it at extreme ranges, but it is very, very competent for CQB)
Very unique (I know of only three people, including me, who own one. Those other two are the other two reviewers.)
Extremely realistic (it even has G36-Style locking lugs on the nozzle face.)
Cons:
The FPS Variance is a little extreme. See above.
You run through your mags very quickly (more from the fun factor of shooting than anything else)
The trigger group is a continual worry for me; I have heard of them experiencing issues and it doesn't appear to be too sturdy. However, I have experienced absolutely no malfunctions of any kind.

TL:DR
This is amazing. If you feel like augmenting an already awesome kind of gun, then I recommend this. Magazines, while really good, also happen to be dirt-cheap for GBBs, as well!

"Ok, like the below posted review, I expected this to be difficult. I was right. I bought a boneyard Umarex g36c, and this gas kit. There was a massive amount of modification required, and I am very glad that I own a dremel. The rod part of the kit does not fit at all into the rear adapter, and required a lot of shaving down. Other then that, most of the kit fit fairly well tighter, requiring only moderate modification. I installed a longer tight bore instead of the barrel that came with the gun, and am fairly happy with the result. After greasing the system, and minor adjustments, I am happy with my new Gas G36. I find that mine is particularly gas inefficient in full auto, but very efficient inn semi. the weapon has good kick, a good look, and a solid feel.

"First off the bat I received an opened package with broken charging handle and scratched up parts, downer. I went in to this project with a dboys g36 expecting it to be difficult to make it work and boy was I right! After a bunch of sanding and dremeling the inner parts of my receiver the bolt moved smoothly and reciprocated just like it should but I ran into a snag. The hop up will not fit at all into the gun without chopping up the front and building a new piece to hold the threads for the outer barrel and the hopup chamber in place. Looks like I'll have to cast my own hopup after all. I think it's a bit strange that I've interchanged a bunch of parts from a worn out ares g36 into this gun and it still has problems with this kit. It didn't really fit that well in the ares receiver either because of the hop as well but can get hammered in if need be, but I'd rather keep an ebb and a gbb just for the range of options. Aside from all that this thing has a great crisp kick and epic sound. It has decent efficiency, final shot bolt locking, manual bolt locking decently reduced cool down effects, nice weight, a solid trigger group, and has a great selector system with tangible and audible clicks when changing firing modes. Another plus is mags are relatively cheap. Downsides are as follows: the hopup is not so great for clones. The bolt is mms too wide and requires breaking in and or sanding guide rails. A lot of the internals are pot metal so will wear down a lot. If you take on this challenge make sure you have your wits and patients about you. The charging handle is flimsy plastic (never got to use mine) the parts have a thin fragile coating applied and will scratch easily so make sure to disassemble and clean until there's no more paint chips floating around in your gun. All in all, not too bad. But not even close to a shopping experience I would call ideal.
