If you’re shooting long distances a bubble level is strongly recommended. It will help you keep your shooting platform at a horizontal level reducing the margin of error. Most of the scope mounts from Spuhr have a bubble level built-in at the bottom, shown towards the shooter. Due to its location, it can be a little difficult to spot where the bubble is, so Spuhr has developed a new version called the A-0119.

Their separate bubble level is made with a 1-degree offset, and with two set screws, you adjust it to your bubble level in the mount (or whatever other reference you chose).

The bubble mounts directly on the interface of their ISMS mount.

External Bubble Level Assembly designed to attach forward on the scope mount body or ring. Perfect solution for shooters who are unable to focus on the built-in level in the standard ISMS series or who has a model without a built-in level.

The angle of the assembly can be adjusted using two set screws. Includes screws.
