The Devtron Scopecoat is constructed using high-quality Neoprene core, and laminated with Nylon. Its simple yet effective design safeguards your scope against dings, scuffs, scratches, dust, dirt, and moisture. The absorptive qualities of the Neoprene draw moisture and condensation away from your scope and helps protect it from the elements. Our standard Scopecoat is available in Black, Natural Gear Camo, Coyote Brown, Dark Earth and other colors upon request. Scopecoat stretches approximately 10% and the "perfect fit" is a matter of personal preference -- ranging between a relaxed fit to a more form-fitted one. - Fits: Trijicon ACOG Compact/EOTech 3x Magnifier- Black
