Used, but hey, it's 2.5# of solid steel so how would you know? Comes in original packaging and with original nut (never used).
Purchased shipped from Armalite on 6/23/2010 for $190 shipped. Currently out of stock. I will send original invoice with the brake.
This is the best 50 brake available, I think is the general opinion.
$160 shipped to CONUS. email me at firstname.lastname@example.org
