Machined aluminum mount designed by world-champion three-gun competition shooter Matt Burkett clamps to Picatinny receiver rail to provide a secure mounting point along the bore axis for a red dot reflex sight. Positions the red dot next to the primary optic at a 45° angle for instant transitions from scope to red dot to engage close-quarters targets. Just roll the rifle slightly to the right or left to engage the target with the red dot. Substantial "wings" protect the sight from impact; may be removed if desired. Cross-bolt with large easy-to-grasp thumb knob lets you quickly install or remove the mount-plus-sight as a single unit.
