Get on target, range, and take the shot in seconds - all without lifting your cheek from the stock. The NIKON M-223 Laser IRT 2.5-10x40 Rifle Scope, BDC 600 Reticle, Matte Black (8491) combines the speed and precision of a Nikon rangefinder with the accuracy potential of the M-223 riflescope and BDC 600 reticle. The Nikon Laser IRT Scope ranges distances from 32 yards to 735 yards in 1 yard increments with ease.
The M-223 IRT provides the equivalent horizontal range to the target, features one-touch laser technology that keeps ranging and displaying distance for 12 seconds with a single push of the button and an integral mount for Picatinny Rails.
With an impressive 4-time zoom range and four inches of constant, non-critical eye relief, M-223 Laser IRT Riflescope features a massive ocular lens that delivers a huge, exceptionally bright, high-resolution sight picture.
This Laser IRT has a smooth zoom control, with help of which magnification reference numbers are viewable from the shooter's position. Precise, 1/4-MOA hand-turn adjustments get you zeroed in quicker and maintain your setting - even with heavy recoil. Quick focus eye piece allows the shooter to instantly bring the reticle into sharp focus.
To simplify field adjustments, Nikon has integrated Zero-Reset turrets into all M-223 riflescopes. Just sight-in at 100 yards as usual, then lift the adjustment knob, rotate to your "zero", and re-engage. Field adjustments are now as simple as dialing-in your subsequent ranges.
Developed specifically for the trajectory of the .223 Remington / 5.56mm NATO round with 55 grain polymer tip bullet with muzzle velocity of approximately 3240 fps, the BDC 600 reticle offers shooters unique open circle aiming points at 200, 300, 400, 500 and 600 yards with additional hash-marks at 250. 350, 450 and 550 yards.
