Is there a group buy going on somewhere? I heard that a while back you could get Vulcans in quantity for 35 each? I need 4 or 5

I want to build a few guns up and not use flats.

Anybody?

I think Global Trades/Armory USA receivers go for about $50 ea in the white.  My advise is to pony up the extra $8 and get it parked.

Vulcans are more expensive and the trunion holes just aren't right- your magwell ends up being too tight front to back.  Also, watch the lower part of the lower rails for excessive contact with your mags.

Other than that, cheapest way is to fold yourself.  At least you won't have to drill all the holes and dremel the hell out of it to get it shooting like you would on an '80%'.
