Jaeger-
tho i cringe at the thought of converting a FR-8 to a sporterized configuration, i will admit that i had similar thoughts for one of mine once...
i prefer military rifles in their "as issued" configuration but anyway, your rifle, your choice, but i'll make a suggestion that may save you a bunch of time and money, find a Weaver #92A scope mount (it's the one pc. mount for a Thompson/Center Contender) this will fit the radius of a military "stepped" mauser bbl and the mount should only cost about $6.00 and takes 3 screws to mount. much simpler and cheaper than the Ashley Outdoor mount on my Remington Seven Scout
