Found a few online, saw one brand new (supposedly) for $1400, the rest were in the $1600-1700 range.
I understand what its based off of, and what it is made for. For me though I'd save $500-700, get a nice rifle still, and hike the extra 2-3lbs around. And yes, before someone chimes in about how much of a difference two pounds makes I've got more than enough experience running around with lots of gear on my body. Maybe when I'm 70 it will make a difference, but to me now, it's a marketing gimmick that sells rifles to guys who like to brag about how light their rifle is.
