Thanks Jim, thats why i'd like to get some info on the scopes I have sitting on the shelf.
The k2.5 appears to be on demary's Ok list for the A4 but I'm trying to stay within the intent of the rules regarding mounts and rings as well. The period appropriate rings appear to be the type that require the scope to be slid in to them. The 60-b, I'm pretty sure, is not factory sealed so taking off the objective lense shouldn't be a problem. The brighter of the two scopes however, is the C3 with the duplex reticles. If this is factory sealed I would have to find more contemporary rings and then hope they would be approved.
Then there is the issue of what the adjustement range is (how many clicks in the scope and how many MOA per click). This might require shims under the front of the base(a procedure that was common in the era) but is something I'd like to avoid if I can.
Hence, the questions at the top:
Does anyone know the MOA per click on these models and are either (or both) factory sealed?

thanks,

Art
