This Sightmark SM39024 Triple Duty Universal Laser Boresight With Retractable Caliber Arbor self centering provides the most convenient and accurate method for sighting in rifles and pistols of all types. Simply place the base of the bore sight onto the end of the barrel of your weapon and it will attach magnetically as the retractable arbor will adjust to calibers from .17 to 50 Cal. A laser dot will show exactly where your gun is aiming. It's easy to sight in any scope without firing a single shot. Live fire is only needed to fine tune the weapon being sighted in order to compensate for inconsistencies, such as bullet drop due to distance. Perfect for hunters, competitive shooters and law enforcement, the Sightmark Universal laser bore sight is sure to take the frustration out of sighting in almost any gun. It's easy to use and will quickly save both time and money by avoiding prolonged live fire tests at the range. Use the extra ammo for honing those shooting skills and for the hunt. A lightweight carrying pouch protects the bore sight for convenient use in the field. The Sightmark Universal laser bore sight is protected by a Limited Lifetime Warranty.
