Sightmark Triple Duty Universal Boresight

Took this out to the range with my .308 and had my scope zeroed within just a few shots. The universal fit for .17-.50 cal means I can use it on multiple rifles without buying extra kits.

Worked perfectly on my .308 hunting rifle, the red laser was bright and easy to see even in dim light. Made zeroing in a lot faster than my old method of trial and error.

Leveling my AR-15 was a breeze once I had the right tool—the universal fit works perfectly across the .17- to .50-caliber range I own. Being tested by the National Tactical Officers Association gave me real confidence in its accuracy for sighting in.
