With the cost of ammunition still high, who can afford to expend rounds just sighting in? Save that precious ammo with the Sightmark Red Laser Bore Sight!
This Sightmark Red Laser Bore Sight is built to the same dimensions as a 5.56 NATO / .223 Rem. cartridge. It fits directly into your chamber and projects a bright laser beam out of the bore. You can then adjust your sights or optic to align with the dot representing the point of impact, saving you dozens of rounds that would have otherwise been spent sighting in.
This bore sight can be used to sight in your 5.56 NATO / .223 Rem. rifles at up to 100 yards. The brass outer casing will protect the internals of the device without marring your chamber.
