I have up for trade,, A ZRO Delta AR-15 Range Ready model with US Optics scope. I don't have any specific trade in mind, but something in .300 blk would be cool. I also really like this rifle so it would have to be a cool trade. I mainly just want to see what is out there. FYI, it has the 14.58" .223 Wylde barrel with a pinned and welded muzzle device bringing it to the required 16".
