These are two of the most commonly available commercial scopes legal for CMP Vintage Sniper competition on the 1903A4, M1C and M1D guns. Most have been well used and may need internal cleaning, lens work or reticle repair. These are not sealed scopes with inert atmospheres as the vertical Redfield split rings require partial disassembly. I flush with nitrogen or argon at least when re-assembling.
So with that said most people are too afraid to disassemble these old optics as I guess there is black magic or voodoo inside. The few professional options available have about a year turn around for what amounts to an hour or to of work in most cases. It is getting parts that is the hard part.
As you can see below there really is nothing earth shattering or NASA related to these.
First the Alaskan. This Alaskan has a simple tapered post. This post is 3 MOA wide (really blows). Therefore she is getting fine cross wires.
Next is a Weaver K2.5. This is a non-suffix scope (no 60B or C or whatever). This scope is much more simplistic than the Alaskan.
