Thanks, that sounds like a good deal.
Had though about building one, but the is probably less than it would cost to do it by components.
I have one priced out on Brownells right now at 1400, without the barrel. Has all the goodies I would put on the one from DPMS eventually, but unshootable without the BHW barrel I want ot put on it. The barrel is $320 or so. Thats about 1800, cheaper than the SASS and other high end guns from DPMS, Armalite, etc., but still 800 more what the GS vendor was asking.
