Holosun HM3XT 3x Titanium Magnifier w/ QD Flip Mount

Holosun HM3XT 3x Magnifier is an optical accessory designed to add fixed 3x magnification to compatible non-magnified red dot or holographic sights. Mounted behind a primary optic, the HM3XT allows shooters to transition quickly from close-range, unmagnified engagement to magnified aiming for improved target identification and precision at mid-range distances.

Manufactured by Holosun, the HM3XT is built for rifle platforms that use Picatinny-mounted optics and magnifiers. It addresses the need for rapid adaptability by combining a compact magnifier body with an ambidextrous flip-to-side, quick-detach mount, allowing the magnifier to be instantly deployed or stowed without removing it from the rifle. Included spacers support common co-witness heights, making it compatible with a wide range of red dot setups.
