Not cost effective as far as I know......and since they don't do all the other stuff. I think your only two choices are Gen 2 Mildot or Gen 2 XR...less you really want to pay for a Horus.
I'm interested as well. E-mailed Paul a few weeks back about my 5-25 Gen II XR wanting a thicker reticle. Wondering if they will offer the MSR, H2CMR or something with a dot in the middle? More options would be nice.
