yea Harrison and ARP definitely knows about AR platforms. The 6.5BR and BRX aren't for the faint of heart though, you have to know what you're doing when loading as you will need to make or form the brass, use the proper neck sizer, and develop some loads for it. The Kreiger Criterion is a button rifled barrel, but the idea of this barrel from ARP isn't for winning 1000 yard matches but to be faster than the grendel for the same length barrels and to be used for hunting to reasonable distances.
