The Sightmark Slide-to-Side 30mm Mount was created to work with your 30mm Sightmark Magnifier in conjunction with a reflex or holographic weapon sight. The slide to side motion of this mount was created so the shooter can use the magnifier for long distance shots and quickly move it to the side to use the 1x magnification of a reflex sight. The Sightmark Slide to Side 30mm Mount features a quick detach lever, so the mount can be mounted and dismounted at ease. The Slide to Side 30mm mount gives the shooter versatility in the field. This mount is constructed with durable aluminum to stand the test of time and is protected by Sightmark's limited lifetime warranty.
