I called Mike Rock directly and spoke to him for about an hour. He was very accomodating and seemed like the kind of guy you sit around the fire and shoot the #### with. I have heard nothing but good things about his barrels, especially in the tactical/sniper type rifles. I now have a Rock 22" 5r barrel with the heavy flutes on my 700. If I could shoot as half as good as the barrel, I would be happy. I don't do it any justice. It also cleans like a dream I looked at it through a borescope and compared it to a factory Remington Chrome Moly barrel on a LTR. The LTR barrel looked it had been cut with a hedgetrimmer compared to Mike's custom stainless barrel.
