One Piece Scope Rail for 99

Do any of you folks have any experience with these solid one piece scope rails for the 99? It looks like it might give a little more rear adjustment to mount a scope. They are a bit steep, but if it does the job no other mount will do, then it might be worth it.

I always use a Redfield of Leupold one piece mount, never liked Weaver style rings.

I have never seen this till now, its just what I'm looking for. thanks for finding it and ill let you know how it works, as long as the holes line up for a 99c
