ACM is a generic term as far as i know for a Chinese made AEG.
JG and ACM guns are on the relative same in terms of quality. ALthough that being said some JG's have been fantastic and some not. Im not sure of the quality of the JG G36C, but i've been told the newer models (2009+) are fairly good quality.
Enjoy your JG/ACM!

ok thanks,
Not sure ill buy it was more looking for a ca or kwa.

what was this person asking for this gun cause that would also help with the Buy option.

If its cheap might be ok for something to work on

he was asking 350 which i bielive is way to much.
Even do he has a scope/red dot/case

What do you guys think would be a good offer for that gun.

I was considering offering him like 200 since its not realy the gun that im looking for

with out knowing a brand and such, I wouldnt offer more then $100 because for all you know it could be a BE brand and they sell for that much even here in Canada......

Note that AGM and ACM are not the same!

AGM = Airsoft Gun Manufacture(er?) (I don't know if the Engrish is there on purpose)
ACM = "All China Made" (Usually for low quality stuff ie. Okley, Abibas, Sqny) although it would be proper to say that Nike is ACM it's high quality enough that it's not considered ACM.

If it was AGM I don't know but $250-275 would seem like a fair price. If it's "ACM" then I'd be a bit wary about it since you don't really know where it's coming from and what kind of tolerances/QC there is on the factory that made it.

Given that it was tinted though and if it did come from China I'd predict it's a JG (VA/Velocity Arms "OEM" rebrand). If it came from Taiwan it could be SRC (Star Rainbow Company, I know a great name right?), or G&G "Guay Guay Airsoft".

have to agree for 350 you could get AVed and get something in the classifieds

even with an offer of $200, without knowing more about it you could walk into something that will cost you alot more just to get it game able

Im predy sure its a acm he seemed predy confident,

Damn if only he had a allen key to open it and see on the gear box....

I dont know if i should even make him a offer if its a acm....probably not.

Is it possible that it could be one of those Techfast rebrands?

I have no clue the only way to be realy sure is probably to open it,

and he doesnt have the tools to do it so thats why i probably wont make a offer, i dont wanna buy it and find out its scrap.
