Built around an accurized National Match M14, the Vietnam era M21 Sniper Rifle owed much of its success and effectiveness to the Auto Ranging & Trajectory (A.R.T.) scope designed by James Leatherwood, co-founder of Leatherwood/Hi-Lux Optics. The original 3-9x40mm A.R.T. scopes provided a very simplistic approach for tactical marksmen to determine range. The shooter simply zoomed in on a target of known size (18 inches or 1 meter) until it was framed between the proper brackets...steadied the aim...and eased back on the trigger. The Leatherwood Camputer automatically compensated for the range and for bullet trajectory.

The current 2.5-10x44mm M-1000 A.R.T. scope is an updated and more versatile version of the very same system - and it can now be calibrated for the trajectory of a wide range of popular center-fire rifle cartridges from .223 Remington to .50 BMG. Hi-Lux Optics has also gone in and made the integral mount stronger and more solid. This scope can be mounted on most any picatinny rail or Weaver base.

The optics of this scope are far superior to A.R.T. scopes of the past as well, incorporating modern high quality lenses which are fully multi-coated to insure the brightest and clearest sight picture possible. Other improvements include a new cam roller that permits easier operation of the A.R.T. system, additional windage adjustment built into the mount, Tri-Center coil spring tension on the internal erector, and Fast Focus eyepiece that allows multi-shooter use. The new M-1000 is also built with Multi-Dial turrets, which permit this scope to be pre-programmed for up to 4 different zeroes or different rifles. The reticle of this scope also includes the Hi-Lux Optics "No Math Mil Dot" system, which lets you actually know the range before you ease back on the trigger. Once calibrated for your rifle and load, the Camputer system of this scope automatically compensates for bullet trajectory from 250 to 1,000 meters.

The Leatherwood/Hi-Lux Optics M-1000 retails for $459, and comes with a Limited Lifetime Warranty. For more information on this model, visit the Hi-Lux Optics website a www.hi-luxoptics.com, or send an e-mail to info@hi-luxoptics.com.
