I'm picking up a Nikon M-223 3-12x42 600BDC scope tomorrow that I ordered at a local gunshop. Not knowing better I ordered the M-223 one piece mount that doesn't have 20 MOA built in after the dealer didn't order the mount with the scope like I asked him to. Will this mount work with the 3-12 scope, or do I have to return it and get the mount #743 which had 20 MOA built in? I plan on doing a fair amount of long range shooting with my Rock River Arms AR. Any advice would be helpful. Thanks for any advice.
