"For an inexpensive gun, it does the job of being a great primary firearm for private, backwoods, or casual play. The best part about this gun in my opinion is that it is fully customizable at this price. No gravity fed false scope hopper here; you can buy extra mags (buy extra mags, full-auto will eat through your ammo), tactical equipment (red dot sights, scopes, flashlights, etc.) to mount on the weaver rails, and the whole nine yards while still spending under $50 for the gun. And yes, the carrying handle does come off to reveal another weaver rail, you just have to unscrew a tad the screws opposite the knobs, then unscrew the knobs, pull out the screws, then slide the carrying handle off.
As for the build, it definitely feels like plastic, it hasn't broken yet although I haven't put it through the rigors of an all-day game yet. I will say, however, that I am very careful with the gun because I fear something could break with any kind of impact.
Gun did jam one time and the metal inner barrel came out, I was able to push back in however this did (and still does) scare me, especially when I take the thing into the backwoods where things can get lost easily.
The vertical foregrip is junk, does the job but is very wobbly on the weaver rail. The three point sling that comes with it requires assembly and is short on material for a person of average build (I am 5' 10" and have to keep the stock fully collapsed in order for it to fit on me), and quite honestly feels flimsy, I bought an aftermarket Diamond 3-pt sling that feels MUCH better and will last long beyond the life of this gun.
Shooting: accurate. From about a 50ft distance I can hit a grouping the size of a crouched human (using .20gs). Only use .2gs unless you want to shoot with the accuracy of a shotgun spread. Shoots hard for an entry-level gun. Full-auto is unreliable in my opinion, more opportunity for the gun to jam, and you want to be really careful with a plastic gearbox AEG like this one.
I give it four stars for these reasons: shoots hard and straight, fully customizable/equippable, and inexpensive. Perfect for non-competitive, casual play."
