Large riflescopes with big objective lenses and long overall lengths need a cover that actually fits them properly — and the Trijicon Riflescope XL Scopecoat Cover AC21011 is sized specifically for the larger end of the riflescope category. At up to 15.5 inches long with a 60mm diameter, the XL Scopecoat covers the full-size precision and hunting scopes that medium and standard covers simply cannot accommodate properly, giving your large optic the complete, snug-fitting protection it deserves during storage and transport. The Scopecoat AC21011 extra-large configuration covers riflescopes up to 15.5 inches in length with objective diameters up to 60mm — the sizing that fits large precision riflescopes, long-range hunting scopes, and the kind of full-size optics that smaller covers leave partially exposed or force into a bunched, ill-fitting installation that does not provide reliable protection. Getting the right size cover means complete coverage, a snug fit, and protection that actually works rather than just approximately covering the scope. The scope cover AC21011 is made from waterproof, stretchable neoprene laminated with nylon — materials chosen for their combined ability to keep moisture out, absorb minor impacts, and stretch to fit the scope housing cleanly without excess bunching or loose material. The form-fitting design reduces snag potential during pack carry and case storage, keeping the optic guard Scopecoat from catching on gear and pulling loose from the scope during active movement and handling. The Trijicon scopecoat covers AC21011 keep dust, dirt, debris, and water off your riflescope during storage and transport — preserving the lens coatings, turret function, and overall condition of a significant optic investment through regular use over multiple seasons.
