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.
Keeping your rifle in the same position after every shot is essential for accuracy, the Anti Cant Device aids the shooter in keeping the rifle from canting during repetitive shots. These ACD’s are manufactured from 6061-T6 then Type III hard anodized for durability.
Compact bubble level instantly displays the amount of tilt or “cant” as you hold your rifle so you can make fast, easy corrections to improve accuracy. Installs on either side of rail/optics to accommodate both left- and right-hand shooters. The swivel ACD comes with a screw on vial cover to protect the level during storage, but during shooting, the cap can be screwed onto the opposite end’s cap saver for safe storage. Mounts to all 1913 picatinny rails.
