Daniel Defense is one of the best makers in the business. They make a great rail and some of the best cold-hammer forged barrels in the industry. Hunng could probably jump in here and help out on specs or why it's "worth it".
heh, but @Wallace's @mtdawg169 & @GTRider245 cleared things up quite nicely, with a bow on it...in time for christmas too!
That is a nice deal too, if i hadn't just pieced a similar DD upper i would be on it...eh well, back to my super secret Colt Commando project...PIA!
