Anderson lower, all mil-spec parts other than a James Madison Tactical drop-in trigger, 3.5 lb trigger. Nikon P-series two piece cantilever scope mounts with a Burris 3-9 power adjustable scope. Barrel is 1/8 twist 5.56 chamber. I built this rifle from parts for the purpose of target shooting and coyote hunting. Not really a close quarters battle riffle. Could easily build out another upper for a totally different purpose and have a great setup. Ask questions if you have any, contact only through messages on Nextech Classifieds until arranging to meet for purchase.  $650 as is or $550 without the scope and mounts, carry bag pictured not included.  Not interested in trades, cash only!
