The only reticle offered is the EBR7B which is close. Im assuming you like the numbers on the outside of the holdover tree instead of on the centerline. I own both scopes and never payed anymind to the difference until now. Seems like it would be easier to have the same reticle in each. The EBR7C would be the winner.
In time they probably will. They have changed the AMG reticles in the past. I imagine they will want to use up their 7b stockpile first before selling the 7C.
It's a difference that people will talk about, but I seriously doubt there are tons of folks out there buying the RZG2 or another brand because it has the B instead of the C reticle. Maybe some, but I can't imagine many. They are darn near identical.
