ok so heres the gun right here

http://www.airsoftpo....06d2f021f352fb


however this review covers all the king arms guns with 7mm gearboxes and working bolt catches

nice bonus features include a working bolt catch

so i got this on a whim and i will say i am quite impressed with the quality of it

ill start with the body it has colt trademarks engraved (not silk screened) and the color of the receiver is quite nice its also metal but not very heavy

it has a 1 peice metal outer barral and a flat top receiver

the magpul stuff is magpul stuff

the internals are also good

the gearbox is a nice quality good finish no apparent cracks or flaws
the bushings are 7mm bearing bushings of highest quality
the gears are nice and steel with no apparent flaws or cracks
the piston is of standard quality as is the piston head
the air seal on the gun was perfect so the nozzle and what not are all good
tha spring guide was a bearing spring guide
it had a m100 spring stock shooting 350w.25s (i test fired others at the store with fps ranging from 330 to 350)
the hop up looks exactly like an element one but metal and it works just like one hmmmmm funny that......
the inner barrel is 6.04mm pretty decent its brass
wireing is a little thin but its silver coated so its decent
the motor is ok nothing too great on par with stock classic army
it came shimmed pretty well too i didnt have to do too much to it it wasn't perfect but it wasn't all wrong


some of these have an issue with the cutoff lever and trigger shuttle not meshing correctly making semi auto into full auto on half trigger pulls



so heres the verdict


external finish 10 out of 10
internal parts 8 out of 10
value 8 out of 10

great gun if your looking to get a budget m4 that needs minimal work to make it competitive
all it really needs is a new spring, better shimming and a new motor( and sometimes a cutoff lever) all in all pretty good out of the box
