he Vortex Anti-Cant Device is precision made so you can be sure both halves match when mounted.
Properly mounted, the Vortex Bubble Level allows the shooter to visualize and make adjustments for CANT, which experienced shooters recognize as rotation of a scope’s crosshairs off a true vertical/horizontal plane.
According to the Marine Corps Sniper Manual, compensating for CANT is critical to accurate long-distance shooting: At 1000 yards, 6 degrees of CANT (visualized as 1 minute on the face of a wristwatch) moves the bullet strike 55 inches from point of aim.
Weekend shooters who find varmints a challenge at several hundred yards are no less immune to CANT: 6 degrees of CANT at 100 yards gives the critters a new lease on life by a full ½ inch.
Installed on a properly mounted rifle or pistol scope, the Vortex Bubble Level uniquely equips the shooter to visualize and eliminate CANT with 100% certainty, 100% of the time.
Mounts in minutes, matches finish on most matte black scopes, weighs approx. 50 grams.
