Wheeler 30mm Scope-Mounted Anti-Cant Indicator

The Wheeler 30mm Anti-Cant Indicator attaches directly to a compatible 30mm scope tube and gives the shooter a visible bubble reference for rifle level. The black indicator can fold inward when it is not being checked, keeping the profile more compact during transport or ordinary handling. Its tube-specific clamp means the 30mm diameter should be confirmed before purchase.

Canting the rifle changes the relationship between the optic and gravity, which becomes more noticeable as distance increases. A level positioned close to the scope lets the shooter verify rifle orientation without adding a separate rail-mounted instrument. The fold-away design also helps protect the indicator when it is not in active use.

This accessory is most useful on precision or long-range setups where consistent rifle level is part of the shooting routine. Mount it where the bubble can be seen from the firing position without interfering with controls. Browse more optics and rangefinders for scope-mounting and aiming accessories.
