The Barska 4-16x 50mm Level Rifle Scope is built and priced to be exactly what you need. With an advanced illuminated MOA reticle, top-of-the-line fully multicoated optics, and lockable turrets, the rifle scope is the precision instrument that endures and performs under any condition. Using the external rheostat, the user can quickly adjust the color and the brightness of the rifle scope's MOA reticle to better fit the current lighting environment. The rifle scope's solid mono-tube construction helps protect the internal optics from shock and impact. This rifle scope is purged to prevent internal fogging, even in extremely cold weather, and is coated with tough matte black anodizing to prevent scratching.
