E-link 223 5.56mm Laser Bore Sight, Red Dot Laser Boresighter Rem Gauge with 6 Batteries

E-link Laser Boresighter provides a convenient, accurate, and cost effective method for sighting in rifles and shotguns of all types. The laser dot will show exactly where the rifle is aiming --- 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. STEPS: 1.Fix your firearm in a stable platform 2.Turn the boresighter to the ON position 3.Inset your boresighter fully into the empty chamber. Avoid closing the action as the extractor may damage the boresighter 4.You may sight in your firearm at any desired distance that the laser is visible 5.Align your firearm so that the laser is centered on the bull's-eyes 6.Adjust your scope (according to the manufacturer's specifications) so that the reticle of the scope matches with the laser and targets alignment. You now have a rough zero that should get you "on paper" 7.Remember to remove the boresighter before attempting to load your firearm with live ammunition. Turn the boresighter OFF and store in a cool dry place Description: Material: High Quality Brass Laser Wavelength: 635-655nm LED Type: Visible Red Laser Sighting Range: 10-80 yards Dot Size: 1.5" @ 100 yds Laser Beam: <5 mW Length: 1.77" (45mm) Batteries Model: 3 of AG3 Class IIIA laser: 5mW or less Package Includes: 1 X 223 REM Laser Bore Sight 4 X LR41/AG3 Battery WARNING: --- Laser boresighter is designed for the chamber sizes marked on the boresighter as well as on the packing label. --- DO NOT attempt to insert this boresighter into a different sizes chamber.
