I have a near mfg tikka t3 ss 12moa rail if your interested. They are advertized as being 10 moa but when you actually talk to Richard Near i'll tell you they are made at 12moa. PM me for info.
I have the EGW. It's fairly soft and marks easily, but does it's job. The scope doesn't lose it's zero. I'm really not concerned about a couple of scratches on a piece of anodized aluminum.
