Thanks for the replies, gents.

To be more specific, this would be for NRA Vintage Sniper Rifle Silhouette, with the rules specifying a vintage scope.

I'm pretty sure this involves Unertl-type blocks and mounts, although they allow some leeway with the scope rule. Does this offer a clue as to the preferability of the A1? As you can see, I don't have a clue.
