Leatherwood ART M1000-PRO 2X-10X42 Rifle Scope

For the 50th anniversary of Jim Leatherwood’s legendary Automatic Ranging Trajectory (ART) scope, Hi-Lux introduces the redesigned ART M1000-PRO. The original Auto-Ranging Telescope (ARTel) was issued to US Army and Marine Corp servicemen over 40 years ago. Since then, Hi-Lux has refined and improved the ART system’s general cam to compensate the bullet drop of virtually any caliber.

The ART scope’s integrated mount provides external adjustment through the Trajectory cam. Selecting the proper cam setting will effectively match your rifle’s trajectory curve to the curve of the trajectory cam.

There are two ways to automatically compensate for trajectory when using the ART scope:

1) Framing known sized targets within the HR1 reticle

2) Dialing the Cam to a known distance

Once the known size target is framed, the ART scope will automatically compensate for bullet trajectory from 200 out to 1000 yards. This means no holdover or guesswork.

The M1000-PRO Trajectory cam has been designed to be modular and interchangeable. Caliber specific cams will be introduced in the future.

Automatic Ranging Trajectory

The Automatic Ranging Trajectory (ART) System was invented and designed by Jim Leatherwood for military snipers in Vietnam during the late 1960s. By using the incrementally adjustable trajectory cam, the new Leatherwood ART scopes can be calibrated for virtually any center fire cartridge from .223 to .50BMG.

HR1 MOA Reticle


• The center of the HR1 reticle has a 2 MOA by 2 MOA cross.

• The opening in the center of the HR1 can be used to frame known size targets that are 18" or 36".

• Every hashmark on the vertical and horizontal scales indicate a whole MOA subtension.

• There are 2 MOA tick-marks that indicates multiples of 5 MOA on both the horizontal and vertical scales.

• The ends of the horizontal and vertical axes are indicated by a 4 MOA tick-mark.

• The ranging scale in the lower right quadrant can be used to frame and range known sized targets from 9"-72" in length or height.

• This reticle is true at 10X.
