Suggested Retail:$45. AXEON Optics Absolute Zero Easy One-Shot Laser Rifle Zeroing Device for Rifle Scopes. The Absolute Zero is designed to take the stress and guesswork out of zeroing-in a scope. This device is much more helpful than a bore sight in getting your scope zeroed in. The method is simple: If two nearly parallel laser beams are pointed in the same direction as your muzzle and those two beams do not move in relation to the muzzle, you can shoot one shot to find out where the bullet lands on your target and make adjustments to your scope. As long as the lasers are positioned on the target in the same place as when the shot was fired, while you adjust the scope, it will be zeroed at 25 yards. All that is left is to adjust the scope to compensate for the bullet rise at 100 yards. The Absolute Zero saves time, money, and ammo when you head out to the range to zero in your rifles. Set up is fast with the new quick attach mount. After just one one shot and alignment of your aiming apparatus with the bullet’s point of impact you’re zeroed. It saves you ammo, which means it saves you money. The Absolute Zero works across many platforms. Whether you shoot a slug gun, magnum rifle, rimfire, pellet gun, or crossbow, you can use the Absolute Zero to get zeroed in. By firing only one shot you achieve cold barrel accuracy—a feat not possible if you’ve shot a box of ammo while zeroing in your rifle. 7 DAY FULL REFUND GUARANTEE ON THIS ITEM IF ANY ISSUE IS FOUND THAT WAS NOT DESCRIBED/PICTURED. 7 DAY STORAGE IS ALSO AVAILABLE.
