SiteLite SL-500 Ultra Mag Green Laser Professional Boresighter
The SiteLite SL-500 Ultra Mag is the premier sighting-in device for professional gunsmiths, hunters, and serious marksmen who demand absolute precision without wasting expensive ammunition. Engineered to be the most accurate boresighter on the market, the SL-500 utilizes an ultra-bright green laser that is 50 to 100 times brighter than standard red lasers. This superior visibility allows for easy boresighting at distances up to 100 yards, even in full, direct sunlight.
What sets the SL-500 apart is its patented magnetic arbor system. Instead of using expanding plastic arbors that can be inconsistent, the SL-500 uses super-strong rare earth magnets to securely and perfectly center the laser within the muzzle. This ensure repeatable accuracy across a massive range of firearms, from .22 caliber rimfire up to .50 caliber rifles, as well as 20 and 12-gauge shotguns. Because no metal contacts the rifling, there is zero risk of damage to your firearm's crown or bore.
The SL-500 comes as a complete kit, including the SRL-100 Scope Reticle Leveler and specialized Ballistic Targeting System software, which allows you to print custom targets for your specific rifle and ammo combination. Proudly used by the U.S. Military, the SiteLite SL-500 is backed by an unconditional lifetime warranty, making it the last boresighter you will ever need to buy.
