Ok, the quest to build the ultimate in smallbore Silhouette rifles continues. I purchased two pair of 1/2 in risers for my CZ 452 Style to get my scope to the above receiver height of 1.47 in. according to the respective manufacturers product specs. (.220 in for the DIP rail, (2) 1/2 in risers for a total of 1 in, and the rings, .25 in. bringing my scope to 1.47 in.) This is just under the regulation limit of 1.5 inches. I did some practice with it and it feels better not having my head down in an awkward position but my cheek has little contact with the rifle so I am not sure how this will work out ultimately, but I am out of things I can do now. No more mods. I guess it’s either this way or back down the road I came to de-modification. We’ll see!
