In 1965, the U.S. Marine Corps began its search for a new rifle and scope combo to serve as their official combat sniper rifle. The goal was to have USMC armorers customize and accurize a readily available production rifle. The Corps settled on the Remington Model 40x, chambered for the .308 Winchester (a.k.a. 7.62 NATO) cartridge, and topped it with a commercially available 3-9x40mm hunting scope with an Accu-Ranging scale. The rifle was designated the M40.
Hi-Lux Optics is now recreating this 1960′s era scope for all of those “old school” sharpshooters among us, those who take the time to know the trajectory of the loads they shoot. However, we’ve made major internal improvements. The optics are far superior to that of the original, with precision ground lenses that are fully multi-coated for maximum light transmission. We’ve also added positive 1/4″ click adjustments to the windage and elevation turrets.

During the early years of the Vietnam War, the Marine Corps decided that they needed a standardized
sniper platform based on the newly adopted .308 Winchester (NATO T65).
After extensive testing, the Marine Corp ordered seven hundred Remington Model 700 rifles in 1966.
The Marine Corps designated this rifle the M40 XB and topped it with a green anodized Redfield 3-9X40
with AccuRange reticle for range estimation.
• The M40 USMC reticle features the same Accu-Range system as the original M40 rifle scope.
• The parallel lines on the top of the reticle can be used to frame an 18" target.
• The approximate range is shown by the smallest number visible on the Accu-Range scale in the lower right quadrant.
• The M40 Tactical Hunter reticle features the same Accu-Range system as the original M40 rifle scope.
• The parallel lines on the top of the reticle can be used to frame an 18" target.
• You can also use the vertical hashmarks on the horizontal axis to frame a horizontal target of 36".
• The approximate range is shown by the smallest number visible on the Accu-Range scale in the lower right quadrant.
• The M40 Tactical Hunter reticle also has 4 BDC marks for .223 and .308. The hashmarks are for 200, 300, 400 and 500 yards respectively. The 600 yard hold is the top of the thick black post below the last BDC tick-mark.
• The center crosshair should be zeroed at 100 yards.
• The BDC holdover are accurate at 9X.
