I picked up their lower complete for $275.00 on sale.Got the 16" upper in FDE ,added the Nickel boron BCG,TacOps CH,BAD selector,and Rodgers super stock,Has Aero trigger that will get changed to a LaRue MBT.Had trouble on the onset with not going into battery.Coating on the BCG had it tight,the some FTF and FTE.Changed the extention tube,buffer spring [both being longer] and buffer which was longer and heavier to Armalite parts.Stock trigger was tight had to push it forward for reset but that went away after a few box's.Ran everything I had 147's 150's,168's.After it ran for function I had the barrel cut down and added a Battel comp and had it welded for 16.1 overall lenght.It also has an EoTech set for .308.For the money I'm real happy with it.
