If you can afford it, buy it. They shoot like a house on fire. Don't believe all the BS about them either. It isn't true. They're made from quality materials and have a 1-12 twist. Mine has a chrome lined bore. I hear a rumor that the new ones don't.
Mine shot a sub moa group with the first 8 shots on a HBR target, at 100 yards. I haven't seen any of them, even the No4 MkI look a likes that don't shoot well. I suspect the reason you see them for sale is the people that originally buy them, aren't allowed to use them in local milsurp competitions. Understandably, they will out shoot almost everything else there. They were built to be accurate and robust and they are.
