Wheeler Anti Cant Indicator Picatinney Rail Attachment

The Wheeler Anti Cant Indicator – Picatinny Rail Attachment is a precision bubble level designed to eliminate rifle cant and improve long-range shooting accuracy. Mounted directly to any standard Picatinny rail, it provides a clear and repeatable visual reference to ensure your rifle remains perfectly vertical before every shot. Even a slight amount of rifle cant can cause significant point-of-impact shift, particularly when dialling elevation or using holdover reticles at extended distances.

Unlike scope tube-mounted levels, this version attaches securely to a Picatinny rail, making it an excellent choice when scope tube space is limited or when using optics with oversized turrets or accessories. A precision adjustment screw allows the level to be calibrated to your individual rifle setup, while the folding design lets the indicator be tucked away when not in use to protect it during transport and storage.

Manufactured from precision-machined aluminium with a durable anodised finish, the Wheeler Anti Cant Indicator is lightweight, robust and built to withstand demanding field conditions. The easy-to-read bubble vial remains visible from the shooting position, allowing you to confirm a level rifle without breaking your shooting position.

Ideal for precision rifles, hunting rifles and long-range target setups, the Wheeler Anti Cant Indicator – Picatinny Rail Attachment is a simple yet highly effective accessory that helps maximise consistency and accuracy with every shot.
