I have a Tasco rubber armored scope with an intergal rail on the bottom. It does not look like weaver, but very close. the bevel is different than a weaver. I have the carry handle weaver mount, but I am missing something to connect the scope to a weaver base.

Please tell me what the missing piece is, and how to obtain one. In the Armalite catalog, there is a piece that says "Stanag to weaver converter." Is this what I need?
I have never seen a scope with a rail on the bottom side, however it came with a Colt pre-ban AR15. The scope has the Delta logo on the windage knob.

Thanks,
