The Arisaka Optic Leveler is an affordable, easy-to-use tool designed to ensure your scope is perfectly level when mounted in rings or one-piece mounts. This tool makes the leveling process quick and simple. It includes a base plate that sits on the Picatinny rail or one-piece mount just below the scope's turret cluster. The matching wedge is then inserted from the side—thanks to the 11-degree ramped surfaces, the top of the wedge rises and contacts the turret cluster, automatically leveling it. Included in this product are the leveler base and two wedges, one small and one large. The small wedge fits a gap between the rail/mount and turret cluster from 0.190" to 0.730", while the large wedge fits a gap from 0.680" to 1.200". This ensures compatibility with a wide range of setups. Constructed from 6061 clear anodized aluminum, the Arisaka Optic Leveler is both durable and lightweight, making it an essential accessory for any shooter looking to achieve precision and accuracy. Please note that the optic leveler works under the assumption that your scope's turret cluster and reticle are correctly aligned, which may not always be true with lower-quality scopes. Ensure your scope is mounted correctly with the Arisaka Optic Leveler—it's the perfect tool for achieving the precision you need.
