My smith won't mess with them much either because he said he'd rather cut that wonky bevel on the receiver back and use a standard recoil lug...which gets into recutting the lug inlet in stock as well.The action has a wonky flute at the front. Requires a much slimmer barrel shank or cutting some of the threads back. I've rebarreled a few. Not my first choice. Great factory rifle, there are better options for customs
