    "I have both the V2 and V1 of this kit, and the mags are interchangeable between the two. This kit seriously rocks, I've had it for going on 2 years now and it's been through numerous milsim ops (Ironhorse, Faded Giant 5, Ironhorse 2, Dragon Rogue IV) as well as weekend local play. These are basically set and forget kits, I wanted to see how long it'd last with no maintenance, and I'm approaching 2 years on my original kit (v2) and it performs as good as it did on day one. I like this kit because it supports a vast variety of configurations and will fit in most receivers, the only problem I had was with an APS full metal receiver set that I had to painstakingly file by hand for about an hour, but now it works perfectly. The only drawbacks are: that the bolt carrier is made of zinc so I had one shatter on me in a metal body, and they shoot a little hot (1.5-1.7J) with no way of lowering the fps.

    TLDR:
    Pros- durable, cheap, FUN, accurate, compatible with tons of parts
    Cons- Can't adjust fps, so might shoot too hot for CQB

    "I give this a 4 because out of ALL the good things about this kit. The only major flaw is how stressful this thing is to install! Although once that's done, you will not regret it. I can easily shoot this over 300ft accurately on a mild windy day!

    "I bought this and put in in my G&G cm16 combat machine. It is really high quality and I only had feeding problems with the first few fills of the magazine. Other than that, no feeding problems since!

    Pros:
    Awesome realistic recoil
    Perfect assault style fps
    Mags last 3-4 fills of bbs with just one fill of gas

    Cons:
    Installation required lots of modifications.
    Accuracy isn't like the original AEG

    Recommended if you want something cool! And gas powered obviously.
