The Wheeler Anti-Cant Indicator (brand part no. 766112) is a black aluminum scope-alignment tool built to keep a 30mm scope tube held near perfectly vertical at the shot. Wheeler Engineering designed it to solve a problem most shooters underestimate: canting a rifle even a couple of degrees off vertical shifts point of impact, and with modern drop-compensating scopes and dialed-up turrets, that cant error is easily enough to turn a hit into a miss at distance. The bubble-level indicator clamps directly to the scope tube, giving an instant visual reference every time the rifle comes up. It’s a simple, low-cost addition that removes one of the most common causes of unexplained misses at range.

Key Specifications

• Sized for 30mm scope tubes, clamping securely without shifting the scope’s zero.
• Built from black aluminum construction for a durable, corrosion-resistant mount.
• Functions as a dedicated anti-cant level, giving a constant visual reference for vertical rifle hold.
• Ships at approximately 0.17 lb, adding negligible weight to a rifle’s scope setup.
• Packaged 1 per box, sold as a single unit rather than in a multi-pack.
• Model classified under Wheeler’s Anti Cant Indicator line specifically.

Frequently Asked Questions

Why does cant matter at long range? Even a couple of degrees of cant shifts point of impact, and that error compounds with distance and elevation dial-up.

Will it fit any 30mm scope? Yes, it’s built to clamp onto standard 30mm scope tubes.

Does it affect scope zero? No, it mounts to the tube without touching the scope’s internal adjustments.
