LOL Happens to the best of us. To be honest though the only reason I remembered about the parallax is because I've only been into a ML less than two years. Researched ML scopes but had extra rifle scopes around so went with them. Settled on an Weaver K2.5 60C I bought new in the late 60's and had reconditioned by Weaver Scope Repair Service a bit before he went out of business.
