Attaching a Tasco RF4X15 scope

Okay right now i am working on a custom blaster and am trying to figure out how to attach one of these 6 dollar TASCO RF4X15 scopes to a 1 1/4inch PVC pipe. I have some brackets holding it on now with little glue but i would like to use the actual clamps that came with it. Any ideas?

There is little blocks glued to the top of the barrel (the blocks have grooves in them), then you clamp the scope clamps to that.

Is there anywhere you can buy them or do they have to be custom made?(does anybody here make them?)

I had this delima not to long ago and I don't think anyone makes them. I found a set over at the RPF that's on my blaster now. You could try and carve them out of some wood or plastic. Here is a diagram that was posted some time ago.

Yeah, you can use styrene or pvc and then make the grooves with your dremel.
