Sightmark Laser Bore Sight 243 308 Winchester 7mm-08 Remington

The Sightmark SM39005 is a laser bore sighter that installs in a rifle chamber like a normal cartridge. When inserted, it projects a red laser out the barrel, showing where the rifle is aimed so the scope or sights can be adjusted with fewer live rounds fired.

The unit has a brass outer case and a black finish. It is caliber specific and fits the 243 Winchester, 308 Winchester, 7.62x51mm NATO, 7.62x54mmR and 7mm-08 Remington chambers. The red laser uses a wavelength of 632 to 650 nm and less than 5 milliwatts of output, with a sighting range of 15 to 100 yards, a 2 inch dot at 100 yards, roughly one hour of battery life and an operating range of 14 to 122 degrees F. A carrying pouch is included.
