    "Really nice gun. Basically a WE M4 with a different hand guard since doesn't have the T91 blowback system.

    Pros:
    -Sturdy and well built
    -Shoots consistently
    -No problem with WE magazines

    Cons:
    - Rear sight is tight and hard to remove. You have to lift the spring with a slim tool and punch it with a rubber hammer to remove it, once you remove it you can sand it a little bit and will be easier to remove.
    - I had to shim the bolt catch for it to work properly. It was easy with an aluminum bottle.
    - You have to tighten all parts before using it or it will start to wobble a little bit.
    - Removing the nozzle break is tricky. Remove the pin, put it 15 seconds in boiling water and turn it clockwise, that's it.

    "this rifle is amazing. ill start with the cons

    cons-
    the flash hider is NOT the one pictured (im kinda ocd, so it was an issue for me)
    cant figure out how to get the flash hider off to replace it with a suppressor. so... if evike could pitch in on how to manage that, id love that. it has a nut behind it which can be loosened, but thats about it.
    the rear sight was NOT easy to remove, but when you do, go slow, and use a rubber mallet.
    the stock grip is kinda small and thin, but easy to remove.

    pros-
    hits hard.
    accurate and easy to adjust hop up.
    grip is easily replaced
    the handguard is wonderfully comfortable to grip.


    id say this is a definite buy if you dont NEED the extra rail space, but are happy with functionality. the flash hider should be replaced as the plastic one that comes with it doesnt fit in appearance.

    again, seriously, would love to know how to safely remove the flashguard.

    "I just got this gun a little more than a month ago and it is amazing! It is EXTREMELY sturdy and it looks really nice. I have put multiple mags through it and it is still working like new (I lube after every use, so that is expected). This gun also shoots at around 430fps and it has really nice kick (I would estimate 2.5-3x the kick of a .22lr). The mags are also very well made and hold enough gas for about 2 mags. There are some miniscule things that I don't like though. The rear sight is a pain to get off, I haven't figured out how to take off the flash hider, and the mags have to be loaded one bb at a time like a real m4 mag.

    Pros:
    Sturdy
    Looks bad booty
    shoots really well
    high fps (could be a con for some)
    awesome kick
    sturdy mags
    really gas efficient

    Cons:
    Rear sight is a pain to get off
    hand load mags
    don't know how to take off flash hider

    Overall, this is an excellent gun and I would recommend it to anyone and everyone.
