Product Description

The Arisaka Optic Leveler is an inexpensive, easy-to-use tool for leveling scopes mounted in rings or one-piece mounts. The base plate sits on the Picatinny rail or one-piece mount just below the turret cluster of the scope, and then the matching wedge is inserted from the side. As the 11 degree ramped surfaces of the wedge and base engage, the top of the wedge rises upwards and contacts the turret cluster, automatically leveling it.

This updated version includes an offset slot in the leveler base, which helps provide more leeway on one-piece scope mounts that have ramped surfaces, such as the Aero Precision Ultralite mounts.

This product includes the leveler base and both small and large wedges.

The small wedge requires a space between the rail/mount and turret cluster from 0.190″ to 0.730″.

The large wedge requires a space between the rail/mount and turret cluster from 0.680″ to 1.200″.

Please note: some one-piece scope mounts like those made by Bobro may not have enough space, so be certain to check with your specific scope and mount. The leveler requires a flat surface directly below the turret cluster to function.

Directions for use:

  • 1. Place scope in rings or one-piece mount. Tighten rings to remove slack, but leave loose enough that the scope can still be rotated by hand.
  • 2. Place the leveler base on the Picatinny rail or one-piece mount directly below the turret cluster of the scope. The angled slot should be on the top side.
  • 3. Insert the leveler wedge into the slot on the base from the side until it contacts the bottom of the turret cluster.
  • 4. Gently apply pressure to the wedge until the scope rotates and is leveled.
  • 5. Tighten one scope ring according to the torque specifications provided by the ring/mount manufacturer.
  • 6. Remove the optic leveler.
  • 7. Tighten the other ring according to the torque specifications provided by the ring/mount manufacturer.

Use of the Arisaka Optic Leveler makes the assumption that the scope’s turret cluster and reticle are aligned, which may not be the case with poor quality scopes.

Easy to use..

This optic leveling system is the easiest way to level all of your optics with no hassle. I reccomend grabbing this and saving yourself so much time if you are OCD like me haha.

So easy to use

I have just received my Combo kit and used it straight away on one of my scopes I always suspected wasn't squared to the action. Five minutes later and job done.
This is a simple but effective tool that's easy to use and will out last me.

Didn’t work for 2 different scope setups

It was too thick to work on both mounting a standard 3x9x40 scope for a deer rifle and an AR LPVO. In theory these should work good, the base is just too thick. Kinda feels like a waste of money unfortunately. Don’t buy these unless you’re mounting on something with about a half inch between the base and bottom turret.
