Range Day Essential Laser Bore Sighter — Universal Fit, .17 to .50 Cal
Get on paper in one shot. Universal arbor set fits .17 to .50 caliber rifles and handguns — boresight at home before you waste ammo at the range.
Every box of ammo you fire getting on paper is money wasted. A bore sighter gets you there in one shot — or less. This laser bore sighter projects a precise red dot from the muzzle of your firearm so you can align your scope or iron sights before you ever pull the trigger. The universal arbor system includes adapters for .17 through .50 caliber rifles and handguns, and the unit installs in seconds without tools. Set up at 25 yards indoors or 100 yards outdoors, adjust your scope until the reticle aligns with the laser, and you're ready to confirm zero at the range in one or two shots instead of a box. Invaluable for new scope mounting, after transport that may have shifted zero, or prepping a new rifle before deer season. Battery-included, auto-off after 5 minutes to preserve battery life.
