"I would highly recommend the advanced receiver mlok carbine.I’ve built many guns as a tech/collector.The receiver is basically a vfc Novritch design which is a vfc(nicest externals out there)with matrix trades on it.finish is not as good as vfc kinda shiny.The lower receiver can except my vfc upper perfectly and the upper fits on my vfc fits perfectly on this lower everything lines up perfectly .The mlok rail is aluminum and very nice construction comes w/mock gas tube/block.No wobble at all in stock(awesome)only takes a 1100 mah stick battery in buffer tube.Internals are very nice also:
Gearbox radiused(not too good but done)
Bearings where they should be
Bushings where they should be
Metal selector plate
Nice wiring
Stainless steel b/b spring guide
Compression system is lacking but has a good seal
Very nice electronic trigger control(not a gate Titan but very nice for the$$)
Common gearset(pretty good shim job)
Nice trigger(can change sensitivity)
Motor is junk(not junk but this gun would be way better w/a neodymium Magnet 30/40 k motor in it)
Hopup is like krytac rotary plastic but nice add maple leaf mr hop and proper nub boom shooting lasers.
Inner barrel looks highly polished and has a very deep crown to it
There aren’t any get it I bought this w/a budget build in mind and was highly surprised upon opening box.very nice quality gun add these items and you have a nice setup for less than 300$.
Maple leaf mr hop aeg bucking 60*70* /nub(clean barrel when done)
13tpa/16tpa 30/40k neodymium magnet motor(set motor height w/adjustment screw at bottom of motor grip when done re installing new motor.

"Amazing Gun!!! Built-in it has an adjustable trigger pull setting, which is almost as good as my high-speed trigger on my polar star.
