The Vector Optics 30mm Offset Bubble Level Gen II is engineered to fit 30mm rifle scopes, providing a slim-profile solution to prevent cant and maintain perfect rifle alignment.
Its side-mounted bubble level allows improved visibility without compromising cheek weld or sight picture.
Made from rugged 6061-T6 aluminium alloy, this durable and lightweight mount ensures long-lasting performance. Quick and hassle-free installation is achieved with the included hex key, making it ideal for precision shooters.
What and Why?
Small amounts of rifle cant can cause noticeable point-of-impact shift, especially at longer distances. A Bubble Level helps you maintain a level rifle before every shot by placing a clear spirit level beside your scope where it can be checked without breaking your shooting position.
While a bubble level doesn't improve the scope itself—it helps ypu eliminate one of the most common causes of missed shots: rifle cant.
The offset position allows you to glance at the level while maintaining your shooting position, making it quicker to confirm the rifle is upright before taking the shot.
Because it clamps directly onto a standard 30mm scope tube, there's no need to replace your mounts or modify your rifle. It's an easy addition for shooters wanting greater consistency, particularly when shooting at longer distances where even slight cant can shift the point of impact.
The lightweight aluminium construction adds virtually no noticeable weight while remaining robust enough for regular field or range use.

Will this fit my scope?
It fits scopes with a 30mm main tube. It does not fit 1 inch, 34mm or larger tube diameters.
Does it fit Picatinny or Weaver rails?
The bubble level attaches directly to the scope tube, not the rifle rail, so rail type does not matter.
Can it be used on an air rifle?
Yes. It is suitable for PCP, spring-powered and COâ‚‚ air rifles fitted with a 30mm scope.
Is it suitable for centrefire rifles?
Yes, provided the rifle uses a scope with a 30mm main tube.
Why do I need a bubble level?
Even slight rifle cant can move the point of impact, particularly at longer distances. A bubble level helps keep the rifle consistently upright for improved repeatability.
Does it affect eye relief?
No. It mounts to the scope tube and is designed to sit alongside the optic without changing eye relief.
Is installation difficult?
No. It simply clamps around the scope tube using the supplied fixing screws. Care should be taken not to overtighten.
Can it stay fitted permanently?
Yes. Most shooters leave it installed as part of their scope setup.
Is it waterproof?
The aluminium body is designed for outdoor use. As with all shooting accessories, regular cleaning after wet conditions is recommended.
What should I check before ordering?
Confirm your scope has a 30mm main tube and ensure there is enough free tube space to mount the level without interfering with mounts, turrets or other accessories.
