Tested and recommended by the National Tactical Officers Association and the North American Hunting Club, the Triple Duty™ Universal Red Laser Boresight is designed for sighting in .17-.50 caliber rifles, shotguns and pistols. A key feature to this device is it doesn't have any additional attachment pieces to be lost. Engineered with a self-centering arbor, the unit attaches into the end of the barrel as opposed to the inside, preventing metal from protruding into the firearm barrel. Simply place the base of the bore sight onto the end of the barrel, and it will attach magnetically. Includes a carrying case, three (3) AG3 batteries, and instructions.

"So far not impressed package says works on all rifles nope not my ar even with muzzle break off and so far I can't get my 308 dialed to the laser will try again later"

"Works really well as long as it is in dim light which is not a fault in the device. Just in bright light a green laser shows better with the human eyes. I have the green but my eyes saw it as blurry and 2 or 3 spots until I walked right up to where it was shining and it was nice sharp green dot. With this I ordered the red version and nice and sharp but needed lower light to be seen."

"Most excellent product, easy to use, with any rifle or handgun"
