Delta Optical
Value to premium riflescopes, binoculars, and red dot sights (Classic, Hornet, Javelin entry lines; Titanium and Stryker premium lines) tested by the German DEVA institute.
Delta Optical is Poland's best-known sport optics brand, founded in 2002, and splits manufacturing by price tier: entry lines from China, premium Titanium and Stryker scopes from Japan. UK owner forum reports describe warranty repairs taking several months once a scope is shipped back to Poland, worth knowing before promising fast turnaround to buyers.
Warranty: 10-year warranty on riflescopes per third-party optics retailers; community reports describe the warranty as non-transferable in practice for a buyer who was not the original purchaser, and repairs are routed through Poland with multi-month turnaround.
