Oregonian,
The MTR 4 reticle has ten vertical marks below the center dot. They are 1 MOA at 20 power, 2 moa at 10 power. Overall I like the reticle very much, that is why I got second scope with the same reticle. I got this reticle for hunting applications and did not want it to be too fine. It works good for hunting and lately I have been happy using it in tactical competitions at ranges of 500 yards and under. The 52 mm should be better in low light but I don't yet know how much better. I'm still waiting to get my rifle back from the smith to do some low light side by side comparisons. I believe that the duplex reticles are not glass etched which accounts for some of the lower price for the duplex.
