"I just got into airsoft about 4 months ago and this was my first field ready replica. I love it. It’s never misfed, overheated, or had any issues at all and as a starter I think it’s so easy to work on. I threw on an moe hand stop, sig Romeo 5 and some random mock suppressor to make it look a little longer and this thing is a beast on the field. I’m about to start upgrading internals but for now she’s beautiful out of the box.

"A good budget AEG rifle for beginners as it has decent build quality and it's pretty sturdy too. I'm not sure why evike recommends an 11.1v lipo as I started to have a problem with it burst firing on semi which was probably due to the gearbox overspinning from the high voltage, but I was able replace the gearbox and it works as good as new. So I'd recommend buying the 7.4v lipo so the gun can last longer. Overall it's still a decent rifle and with simple upgrades can perform like mid-high range AEG rifles.

"Too much defects:
Very Low quality
Gearbox shell itself.
Holes for bearings not leveled, why gears jammed in bearings.
Cylinder bore is stamped and sharp as knife inside so it will damage piston needs to be sanded from inside.
Nozzle tappet is not regular shape, why gears not rotating freely,
Tappet needs to be replaced by regular or reshaped as regular. If not replace or reshape nozzle tappet gears will be broken.
On my was broke after 3000 BBS.
No grease absolutely dry 3 pcs bearings.
No grease absolutely dry piston slides.
No grease absolutely dry nozzle tappet.
BBs jamming because lower bucking lip stick outside and jamming inside by bbs. I cutted lip about 1mm and grind lip inside diameter wider. Actually not bucking problem but hopup chamber shape.
Short battery wire connection.
Plastic gun shape curved as bow.
Very thin plastic shell.


Pros:
400 fps spring installed
Cylinder (ported) / barrel ratio for light weight .20 bbs
Will loose Joules on heavier bbs anyway .30 fly better.
Barrel clap is quiter than others
Light weight
Short lenght
Good motor
Perfect sights
Perfect regular switch trigger
Perfect regular wired mosfet
Stainless cylinder
Strange steel inner barrel teflon coated but works perfect when new
Hi cap magazine

After all internal repairs, correct greasing and upgrading now it shoots perfect. Playing only .20 bbs bio.

I do not recomend to buy if you are not a tech man. This toy needs a lot time before it will work as should.
I had much better experience for cheaper.
