Looking for opinions from experience players about the gun.

KWA CQBR is my choice.

If I buy another M4, I'd get that.

I approve this message. KWA has been on the up and up lately. As a self proclaimed Master Tech Airsoft Replica tech , an ATA (Airsoft Technicians of America) approved status , KWA's have been doing good stuff, especially in the GBBR area.

Choice A already has a few upgrades done to it like the 6.03 tight bore inner barrel and looks like pretty good FPS. I would buy that one.

To answer your question OP, you'll be unhappy with all three choices. To meet your accuracy requirements, you're going to need most field's maximum of 400 fps (1.5J), if you believe physics over marketing. At 150 ft, even a .30g bb will drop a foot in perfect conditions: http://mackila.com/airsoft/atp/07-b-08.htm

It's a myth that tightbore barrels are more accurate. A cheap Chinese-made chrome-plated brass 6.01 barrel will not outperform a stock Tokyo Marui 6.10 barrel. Straightness of bore and polish are more important.

From the three you've listed, the G&G is probably the best, but that's not saying much and the electric blowback will be cool for about ten minutes before it starts to annoy you. It has no other purpose besides being tacticool.

I don't know whether you have decided yet, but If you know a nearby tech who knows their way around a gearbox (shimming bevel to pinion, AOE, Hall sensors) I would recommend building your own gun. YOu could make a much better one for less.

I also just noticed that it is the Blowback G&G. I would avoid Blowbacks because though they may be cool for a bit before they become annoying, and if you ever have a problem they run a 2.1 Gearbox.
