I have built on several of these receivers and will be blunt about my opinion of them. If you want to build a general big game rifle, they will be alright, but for the price you pay for them its hard to justify them for just a general normal range big game rifle when a standard Win M70 will perform just as well or a Rem 700 will totally out perform one.
AS for a custom receiver, they rank pretty low in my book from actually getting them and taking critical measurements to see how true they are, not very to be honest.
STill the ones I have built on did meet my 1/2 moa accuracy requirement but I only tested that at 100 yards.
Simply put, they would not make my short list for custom receivers I would recommend for accuracy work. Again, for a general big game rifle, they work fine but know what your getting before you spend the money. If you want a LR rifle, go with another brand.
