I bought the No-Tap Ring Mounts and a Leupold VX-II 3-9x33mm Rimfire EFR Rifle Scope from Optics Planet for a 1961 Marlin 39A Golden Deluxe. I installed the rings and scope without a bore sight (carpenters eye) and was able to site it in to 1" groups at 50 yds in just 9 shots (3-3 shot groups and only 2 elevation adjustments). Leupold makes a Great Scope!!
Optics Planet is an excellent online storefront and offers the consumer tremendous value, selection and service. I will continue to be a customer to Optics Planet unless something changes.
Pros: Excellent Quality and Finish, Precision Machined Parts, Extremely Fine Tolerances
Cons: None
