Arken Ultra Light Bubble Level

Arken’s Ultra Light Bubble Level clamps directly onto your scope tube to help you catch a canted rifle before it costs you a shot — even a few degrees of cant can push a long-range shot off target, and it’s easy to miss without something to check against. CNC machined from aircraft-grade 6061-T aluminium, it’s built light enough that you won’t notice it’s there until you need it. Available in 30mm and 34mm tube sizes.

Key features

• Clamp-on design: Fits directly onto the scope tube — no need to remove your scope or rework your mount to install it.
• Ultra-lightweight: Aircraft-grade 6061-T aluminium, CNC machined for minimal added weight.
• Center-point bubble indicator: Easy to read at a glance, so you can check your level without breaking your position.
• Matte black anodised finish: Durable and corrosion-resistant.
