Thread defect - Leupold ScopeSmith Lens Shade for Adjustable Objective Rifle Scopes

I bought one of these shades for a 40mm Leupold VX3 scope. There were burrs in the threads that prevented it from threading into the scope. I returned it for exchange, and the second one was even worse. I have sunshades for Nikon and Weaver scopes and they are perfect. Leupold has obviously put out a bad batch. I returned the second one for a refund. Maybe wait a few months and try again somewhere.
