Burris Ar-15/M16 Ar-Tripler? Magnifier

When installed behind a non-magnifying red-dot sight, this add-on optic provides a true 3x system for accurately engaging targets at longer ranges. Waterproof, fogproof and shockproof, the AR-Tripler has fully multicoated lenses to deliver excellent brightness and clarity. Windage and elevation knobs allow you to adjust the magnifier on the red center-dot of the sight for maximum effectiveness. When magnification isn’t needed, the quick-attach/detach Adds 3x Magnification To A 1x Optic For Longer Range Shots Picatinny mount lets you quickly and securely flip the magnifier aside for CQB or other close-range applications.
