Swampfox Freedom Rings II cut the fat off our original Freedom Rings for a lighter, more efficient mounting solution without cutting durability. Freedom Rings II are milled from 7075-T6 aluminum and feature a scratch resistant hardcoat finish. This grade of aluminum and finish match with AR-15 receivers, so we reckon it's good enough to be our standard for Freedom Rings II. These rings don't need to be lapped and come with a thin no-slip material pre-installed to help your optic stay level while torquing your ring caps. Never sacrifice strength, weight, or appearance when you can have it all with our one-and-done second-gen scope rings. Mfg: Swampfox Optics
