The Laser IRT (Immediate Ranging Technology) Riflescope combines Nikon's BDC (Bullet Drop Compensating) reticle with an integral laser rangefinder. The laser rangefinder and precision BDC reticle work together to provide precise distance measurement, proper aiming point and speed for immediate shot placement. The riflescope also is available with Nikon's Nikoplex reticle. The patent-pending IRT technology returns precise and continuous distance readings for a period of twelve seconds. The Laser IRT Riflescope weighs in at 26 ounces and measures 13.1 inches in length. Eye relief of 3 inches and a low profile mounting system allows the riflescope to be mounted on almost any rifle.
