||This gun is remarkably well built. For $150, you cannot go wrong with this. It comes with a full metal top receiver, full metal outer barrel, full metal front and rear sight. The front hand guard, magazines, and pistol grip is some sort of really tough nylon fiber plastic. The body and stock are kind of cheaper plastic, but it's still hard to break. The internals are really what you wouldn't expect for a $150 gun. It's got a metal spring guide (which most guns don't come with). It's pulling what seems to be a M120, and it's gears seemed pre-shimmed. Watch the prelubrication though, it's horrid. Comes stock with what I think is a 6.05mm inner barrel, which I switched for a 6.02. I swapped my spring guide with a Systema, and reshimmed by gearbox my way. I replaced the lower receiver with a G&P Supreme Grade metal body and added a custom made stock sling point. The Echo 1 Dogs of War magazines wobbly like mad in the stock body, but with a little bit of tape, it's an easy fix.
Problems of the gun. The pistol grip can be a little loose if installed incorrectly. The butt plate does come off. Sights are really low to the gun, so it's not good with masks, but it is manageable.
Sum it all up,
385 FPS right out of the box
Very Sturdy construction, only minor flex comes from where the front end assembly meets the receiver.
Hop Up was really unnecessary for this gun.
Very good internals.
Magazines do tend to wobble in the magazine well.
Butt Plate falls off if hit from the top, but that's a problem with all guns.
Sights are mask-unfriendly.
Use .2 and .25s. Any heavier and you might have to adjust the hop up. The problem with the stock hop up is that it WILL make your gun jam.
