Hi-Lux Close to Medium Range 4 (CMR4)

The CMR4 is truly the next generation of tactical scope technology - loaded with advanced design features that truly put it in a class all of its own.

It's built with the same rugged 30mm one-piece high tensile strength aluminum tube, with the same 1-4x magnification range and 24mm objective lens as the first generation CMR. While the lenses of all Hi-Lux Optics scopes feature fully multi-coated air surfaces for optimum light transmission, clarity and sharp target image, we've gone all out to use the best lenses available today in the CMR4.

Many tactical shooters shared that they wanted the windage adjustment moved to the left side, and that's exactly where you'll find it on the CMR4. It allows the right-handed shooter to make windage adjustment without taking the scope off of the target. Both the windage and elevation turrets feature our "ZRO-LOK" System, which locks windage and elevation alignment in place, while still allowing minor adjustments to be made in the field, then being able to return to exact zero. Tactical shooters across the country are now recognizing this system as the best available today. Each click of either turret gives 0.1 Mil adjustment, with 8 Mils per full turn. The CMR4 also comes with protective screw on aluminum turret caps.

The all new and advanced illuminated reticle provides more information to the shooter for quickly assessing the range of an intended target, and to allow for the BDC up to 800 meters. The trajectory of 5.56mm (.223 Remington) or 7.62mm NATO (.308 Winchester) rifles will work well with the CMR4 reticle. In addition to the vertical BDC aiming points, the reticle also includes Mil scales on both the vertical and horizontal lines. Illumination comes in choice of red or green, plus the refined rheostat that allows easy adjustment of the lighted reticle intensity now includes three night vision settings.

Other features include Tri-Center spring tension for positive scope adjustment, Fast Focus eyepiece, and Perma-Coat soft luster blue-black finish for long lasting good looks. The CMR4 is covered by our DiamondTuff Lifetime Warranty.

The CMR4 is built with the same rugged 30mm one-piece high tensile strength aluminum tube as the first generation CMR. While the lenses of all Hi-Lux Optic’s scopes feature fully multi-coated air surfaces for optimum light transmission and clarity, we've gone all out to use extra low dispersion lenses in the CMR4.

5.56 BDC Reticle

• The CMR4-556 is a Mil-Radian based reticle specially calibrated for 5.56 NATO. In order for the BDC holdovers to be accurate, the scope needs to be zeroed at 100m.

• The center dot is the hold for 100m (also used for zeroing). The 200m holdover is the lower tip of the small inside horseshoe. The 300m holdover is the top of the vertical crosshair below the center dot. The 400m, 500m, 600m, 700m, and 800m holds are the subsequent sets of triangles.

• The sets of BDC triangles can also be used to frame a 1/2m (approximately 19") target at their respective BDC distances.

• The dots on both sides of the vertical mil scale crosshair represent the holds for a 10 MPH crosswind.

• This reticle is true at 4X.

Great optics!!! love these scopes!

JMO, I have 3 of these scopes a 1st gen and 2 CMR4 5.56, Hard to beat for what's being offered out there that's a Hi quality optic for the money! Excellent Glass!!! in these scopes!!! These scopes are built like tanks, IMO 4x for a 5.56 AR Platform is all you need, as said I've only sited out to 300m so far but everything is crystal clear at 4x, these scopes are bright and clear and have excellent resolution, for me its like looking thru a higher quality or magnification scope! I run 20x SWFA SS optics on my LR bolt guns, if that give you an IDEA of how good the glass is on these HI- LUX optics! For CQB RED DOT or out to longer ranges IMO This is a hard scope to beat!!!

Great scope

I really like the Reticle easy to get on target fast. Purchase was complete success with fast delivery.

Very Nice optic!!

These are very nice and accurate optics! When one considers the price point, it is a steal! The glass is right up there with optics costing three times as much. The turrets are works of art. They are crisp, audible and the zero stop is very nice. I also like that Leatherwood/Hilux moved the windage to the left side. Very happy with my purchase. You will not regret buying one!


I was very skeptical of this company from the start. At the time it was hard to find a good review for this scope. Luckily a friend of mine had the same on his AR platform and I had the chance to test it out. Since I purchase this scope I have put more than 600 rounds down range with it and it has never let me down. The tracking is true, the turrets are solid and the glass is clear. Even out to 900 yards the drop coincided with the impact on my 18"barreled ar with 62 grain NATO. I couldn't be more impressed.
