I have up for trade,, A ZRO Delta AR-15 Range Ready model with US Optics scope. I am looking to trade for a Mini-14 Tactical, 92X Performance, a S&W 640 Pro, a 360/340 PD, or M&P 360/340. Some cash would probably have to go along with any of the revolvers. I will also consider .300 blk ARs. FYI, it has the 14.58" .223 Wylde barrel with a pinned and welded muzzle device bringing it to the required 16".
