Where to buy GBBR Complete Uppers?

[Mles]

Is there some place where I can buy a GBBR complete upper so I can switch from a DMR to a CQB upper?

You'd have to build one. No one that I know of offers pre-build upper. Receiver itself, maybe, depends on what you are using. For me I am in the WOC-spec receiver, the only way for me to build a 2nd upper was to buy a complete receiver set(including a lower), and use just the upper receiver and I'd have to buy all the associated part to make a functional upper(outer+inner barrel, RAS/RIS, sights, blah blah). If you have a Inokatsu/Prime spec WA system gun, Prime makes upper receivers that sold seperately in MUR or traditional flat top I believe, and there are others that makes VIS or even LMT style monolithic receiver+RAS set. But you still going to need the parts that goes in it. In the LMT case I believe it is sold as an entire set, so you need to buy the lower with it. It is also possible to mod RS upper receiver to fit Prime/Inokatsu lower.

Even WE you can also buy seperate upper receiver, but you still need to build it up.

Alright thanks a lot! I am going to have a WOC soon and I just needed the help. Guess I'll be looking for parts in commerce threads for a while now.

What magazines, besides WA, do you suggest?

So far almost every one has some kind of folly. You are guaranteed to have to work on them to make sure they don't leak. Ones I have that works ok are WA Super(expensive), ProWin(tight fit), older G&P(can't buy it anymore), and King Arms(copy of WA Super). The last one I haven't used it long enough to tell if it'll develop more problem. But thus far, its cheap and cheerful...

Where'd you pick those King Arms mags up? Every retailer I see is out and has been for a couple weeks as far as I can tell. Despite my reservations about King Arms (terrible aeg mids) it'd be worth buying a few to try since if only one worked as well as my WA mag I'd be breaking even vs flat out dropping 100+ on the WA.

I've been debating trying pro-win as well but they seem to have mixed reviews and my experience is that my gun will choose the mags for me.

Edit: Also I think you can get complete WA/G&P front sets, which would at least make it easier in terms of not dealing with assembling everything.

Front set is fine and all, you still need the inner barrel and hop-up bits...

I got a couple when they were new. I guess we kinda need to wait til restock...
