The Arken ABL-30 Arken Bubble Level 30mm is a clamp-on anti-cant indicator designed to keep your riflescope perfectly level. Built around a 30 mm scope tube, it positions a bright, easy-to-read bubble vial just off the maintube so you can confirm level at a glance without breaking your cheek weld.

This compact level is ideal for precision rifle shooters who want consistent point of impact at extended distances. By helping eliminate cant, it supports more predictable elevation and windage adjustments for both range work and competition use. The ABL-30 reflects Arken’s focus on practical, shooter-driven design and precise machining.
