International big game hunter, optometrist, and eye surgeon, Dr. John McCall, broke ranks with the status quo to reimagine conventional riflescope design and functionality. Among the many quality improvements he engineered, he identified canting – rifle tilt – as a critical factor in shooting errors. When the eye isn’t naturally aligned with the scope, the brain misinterprets the image, causing inaccurate shots. 

Stealth Vision’s patented digital anti-cant technology eliminates the need for external level indicators. A green light will signal that the riflescope is level, keeping the shooter’s eye in the objective lens at all times and improving accuracy at long range.
