The Vortex Micro 3x Magnifying Scope is a lightweight, low-profile, and versatile magnifier that works with all of our red dot and holosight optics. Its quick-flip mount easily connects and disconnects from your optic for quick use of both eyes open shooting or enhanced versatility. The lower 1/3 co-witness support allows for absolute co-witness with iron sights. This unique design can also be used as a handheld or headband magnifier with the included mounting base. The lightweight, impact-resistant housing protects your optic while not in use, so you can store it safely in a range bag or backpack without worrying about damage. The included 5 cm sunshade helps protect your eyes and decreases glare when used with firearms on bright days
