Threaded protection for 30mm optics

Dust and debris degrade lens coatings over time. This threaded cap seats directly onto your 30mm tube without tools or modifications. The black anodized finish matches most modern scope rings and receiver extensions. Installation takes seconds—just thread it on when your rifle is in storage or transport. For shooters stacking precision equipment, this kind of protection compounds into longer glass life. Check our California gun-buyer FAQ for more on scope maintenance and optic care.
