Burris Optics AR-Tripler, 3x Magnifier for AR Style Rifle Scopes, Matte Black Finish

Position behind a dot sight to add 3x magnification when you need it or flip-away when you don't. Adjustable to center the dot in the scope, it mounts ideally with the AR-Pivot Ring but also with other 30mm fixed mounts. Excellent coated optical lenses. Wire tethers prevent loss of caps.
