Concept Development Corp.
The Site-Lite SL-100 Mag laser boresighting system takes the guesswork out of zeroing rifles, handguns, and shotguns before you hit the range or field. Instead of burning through ammo to dial in your scope, this laser boresighter uses a magnetic bore adapter and precision laser to get your sight picture on target in minutes. It's a one-time investment that pays for itself in ammunition savings alone.
The system works across an impressive range of firearms: .22 to .50 caliber handguns and rifles, 12-gauge and 20-gauge shotguns, and muzzleloaders. No need to buy caliber-specific adapters or worry about damaging your barrel—the magnetic mounting system uses o-rings to fit securely in your muzzle without any metal-to-rifling contact. The aircraft-grade anodized aluminum construction is built to last, and the super-strength magnets in the center cone hold the boresighter rock-solid for repeatable accuracy every time.
Using it is straightforward: set up a target 25 feet downrange, center the laser dot on it, then align your scope crosshairs with the dotted reference lines on the target. You'll be boresighted for 100 yards. Whether you're preparing a hunting rifle for elk season, zeroing a defensive handgun, or getting a shotgun ready for clay shooting, this system eliminates the trial-and-error that eats up time and ammo.
