Very interesting rifle. The Mauser bolt stop/release is unexpected and a lot cleaner looking.Whoever built this rifle is quite competent.The bottom metal and engraving as well the inletting that I can see in the pics are of high quality. Very nice custom Spingfield. I like the shape of the stock even if some may find it has too much drop for scope use. The '06 cartridge does not have much kick anyways. If the safety lug was ground off and a longer extractor was fitted it could be mistaken for a Mauser.(OK from a distance).
