G36 to M4 Full Conversion Kit for ARES / Umarex G36 Series Airsoft AEG Rifles

"Great addition to your G36, just like it says in the description, you can pretty much drop it in an ARES/Elite Force G36 without any modifications. I cant say for every G36 out there however. The finish isn't 100 percent similar to the ARES G36, however the differences aren't noticeable at all, and its only when you feel it that you feel a difference and even then its hardly noticeable. So far, I tried the magazine conversion kit with MAG, Elite Force, ARES Amoeba, and VFC magazines. They all fed flawlessly. The only downside is the fact that 6 bbs drop out once you take the magazine out or have to reload. Other than that the magazine adapter works perfectly. The only negative I can think of would be the fact it isn't ambidextrous which is more or less just a pet peeve. The stock part fits with no issues, but the button on it is a little gritty.
All in all, if this is what you are looking for to customize your ARES g36, then there is no reason why you shouldn't get it.

"So, I bought this for a Tokyo Mauri g36. IT DID NOT FIT. The magwell feed tube is pushed forward just a bit too far and wont work. The stock however should work with a little bit of filing on the button. The quality feels great however and I would recommend this to Umarex style aegs.

"Got the conversion kit, installed it, but every time I load a mag (Lancer tactical flash mag) the mag resets, when it doesn't reset it does not feed ammo. Tried shooting .12 and .25, same result...
