I am considering trading in my M3 Ultra for a US Optics ST10. This scope resides on an AR10T, and although the Leupold is great, my rifle likes 175 SMKs going 2550, and doesn't match the turret on the M3. I have a USO SN3 5-25 on my .300 win mag, and love the EREK and Mil/Mil combo, which is what I would look for on the ST10. Am I bieng a winey bitch and just stick with the M3? It's very cool in it's own right. I wrote Kenton to see if they could just make me a new turret, maybe that would be a good compromise.
