Vector Optics .300 Win. Mag. Cartridge Red Laser Bore Sight

Vector Optics (Viperay) cartridge laser bore sight in .300 Winchester Magnum. It chambers like a regular round and projects a red laser beam along the bore axis so you can align your scope or red dot before firing the first shot. Saves ammunition and range time; final zeroing is always completed with live fire. Brass body machined to cartridge dimensions, Class IIIA laser (< 5 mW, 650 nm), powered by LR41H button cells. Never fire the rifle with the bore sight in the chamber.
