So far the information i have gathered from first hand and third hand experience is thus
AGM: Lowest inital cost $180 upgrades to get it a skirmish-able replica
http://redwolfairsoft.com/redwolf/airso ... odID=25260
http://www.redwolfairsoft.com/redwolf/a ... odID=26037 upgrade cost 122 plus shipping
NOT INCLUDING THE BULLSHIT YOU WILL DEAL WITH FOR THE MAGS... GHK, Bomber, RA-Tech WA and AGM all make mags for this and the WA and there will be more to come
Total $302 now parts WILL break, like the flute valve but get a differant bolt and hop-up and you will be ready to go
WE: middle initial cost $400 from what ive read, if you order a newly made WE then it is good to go out of the box, but has SIGNIFICANT cool down on full auto, feel free to discuss.
the thing thats gunna eat your pennies is mags since they start at 50 dollars a pop for the WE
again things on the WE system will break too, its ok it seems to be an ok system despite the poor choice of materials they have seemed to have chosen.
WA: Highest Initial cost $600... really why would you NOW purchase a WA when you will replace all the same stuff that you will replace on the AGM version?
I do not mean to discourage from buying the G&P WOC version since it has been reported that all the daft bullshit on the WA is fixed here but that is for people to report themselves since i dont own a WOC...yet The only good thing to come out from AGM copying the WA is the fact that now like 7 companies make compatible mags, and when there is a large group competing for sales, prices drop and favor the buyer
The other contender i haven't been able to find a scrape of information on is the WE SCAR, at its price point if you have already taken the plunge on a WE m4 and want to use your mags on this gun awesome.
I would rather someone else chime in here and show me that the WE SCAR is Gods gift to us for gbbr's.
The last two things i would like to leave here are as follows
agree or disagree Post it here, the more information there is about the GBBR replicas the better infact if you yourself want to know all there is about such a deep subject also follow the arnies thread about the ACM m4 GBBR

Really after sifting through the people asking the same questions about the hop up over and over again(which is why I believe you should change it Immediately, unless it works perfectly for you) it turns out to be a great GREAT resouce on how to make your out of the box AGM m4 the phony pony tits
the other thought, RA-TECH is a great place to find really neat stuff for you gbbr replicas here is their link
