I have been doing some freelance work with Meopta and I can assure you that Meopta products and prices are second to none. Meopta makes all the major components for all of their optics in the Czech Republic. They have been known for years for their glass quality and have produced products for other high-end companies that might surprise you. I have used 2 of the Optika5 scopes and hunted with one last fall. Impressive glass and excellent in low light. All of Meopta's scopes can be dialed in using Strelok Pro which is a huge asset when using a BDC/Cal. Specific reticle. Getting accurate distances for your shooting data makes all the difference in down-range accuracy. The Optika5 are all 1-inch tubes and the Optika6's are 30mm. Kenton makes Custom Turrets for both scopes if that is what interests you? Feel free to drop me a note if you have any questions. Meopta also has a LE/Mil/First Responder program to assist those who look out for our well-being.
