Bill, you remind me that the older Swarovski eps also fit other brands.
I used the older 22x designed for the AT/STs on an ATM65 and Vortex Razor. Quite nice if you don’t mind having only 55* afov.
Also, talking of the other brands, don’t forget that the magnification is different with different scope focal lengths.
So on my Razor 65 there is a 20% reduction in mag. Swarovski 30x is 24x, 20 becomes 16, and so on. On the Helios FM85 it stays the same however.
Real fov increases correspondingly with lower mag too.
