A Quick Note About Scopes And Their Lenses

If you are not interested in the “techie” stuff, you can skip this part, but it has some helpful information that goes to the heart of this (or any) scope review.

Consider an 8-inch vital zone (medium size antelope) viewed at a distance of 750 yards. Some quick math reveals that the target’s included angle size is a minuscule .017 degrees! That’s like aiming at a dime at 100 yards. A rifle scope is essentially a telescope with a crosshair built-in. Here are some of the issues that affect your rifle scope’s ability to see that tiny target clearly:

  • Lens alignment is critical. If a 1-inch lens inside a 30mm tube is misaligned by more than 50 millionths of an inch edge-to-edge, it will degrade the scope’s focus. Machine accuracy on that scale is costly.
  • Multi-Coatings improve image quality because light bouncing around the optic interior washes out detail and blurs colors. Manufacturers of quality optics add up to 80 thin coatings to optimize each of the primary colors’ transmission. Super-critical application of multiple lens coatings is costly.
  • Manufacturers such as Schott Germany produce ultra-high quality, very low dispersion glass, which results in superior images. Light transmission and dispersion are measured at the molecular level. Ultra-high quality glass is costly.
  • Assembly procedures and quality control measures that ensure perfection in every aspect of a scope’s performance are very costly.
  • Add all of those costs together, and you can see why top-of-the-line optics come with a stratospheric price tag.

BOTTOM LINE ON VALUE: Most folks will never have the opportunity to shoot with a three thousand dollar scope. I have, and the difference is visible, measurable, and tangible. But don’t despair. 

Significant improvements in lens making, manufacturing, and machine assembly in just the last ten years (especially in the Pacific Rim countries) have narrowed the gap between the genuinely magnificent the merely great rifle scopes. That means you can get a scope like the Athlon Argos BTR 6-24x50mm for a fraction of the cost and still nip at the heels of greatness.

Athlon Argos BTR 6-24x50 Review

athlon argos 6-24x50 review

The Athlon Argos BTR 6-24x50 is a Solid, Budget-Friendly First Step Into Precision Long-Range Shooting.

I am always into value for the dollar. I am willing to give a legit scope maker a shot, so to speak, when they offer a product that promises to provide superior performance for a reasonable price. 

That's why I have an Athlon BTR 6-24x50mm on top of my Remington 700 chambered in 300 Remington Ultra Mag. I would not hesitate to put one on top of a gun such as a Ruger Precision
Rifle or Savage 110 Stealth as well.

Athlon Optics opened its doors in 2014, established in Olathe, Kansas as an importer of sport optics, including spotting scopes, binoculars, red dots, and rangefinders. I say “importer” because all Athlon products are manufactured outside the USA as far as we know. Here is the breakdown of where Athlon scopes are made.

  • Athlon Neos scopes – Made in China to Athlon specifications.
  • Athlon Talos and Talos BTR scopes – Made in China to Athlon specifications.
  • Athlon Argos BTR and Helos BTR scopes – Made in China to Athlon specifications.
  • Athlon Midas BTR, Midas HMR, Midas TAC scopes – Made in China to Athlon’s specifications.
  • Athlon Ares BTR and Ares ETR scopes – Made in China to Athlon’s specifications.
  • Athlon Cronus BTR scope – Athlon’s top-of-the-line scope and is made in Japan (Light Optical Works LTD) to Athlon specifications.

An enterprise started from the get-go to design in the US and develop links to established foreign suppliers has no legacy manufacturing or infrastructure overhead. The result is a streamlined company with lower operating costs. Athlon can offer good quality scopes at very competitive prices. I consider the Athlon lines to be comparable to Bushnell, Leupold, Nikon, Burris, and Vortex entry-level offerings.

The 300 RUM’s sole mission is to deliver heavy for caliber projectiles at maximum possible distances with maximum possible energy. To that end, the gun begs for a scope with the optics, magnification, and ranging capabilities that stretch both the gun and the shooter to their limits. This review is a "hands-on" evaluation of the Athlon Argos with the pros and cons you need to know.


The “tech” stuff above should prepare you for the inevitable comparisons with the giants. Instead, let’s cut to the chase and talk about what you will actually see through the scope.


The image is clear and distortion-free up to about 16x. From there to about 20x, there is a drop-off on focus that is noticeable but not objectionable. Above 20x, the eyebox all but disappears, and the clarity suffers noticeably.

That is not to say that you cannot use the scope above 20x, but shooters must hold an exact eye position with a good cheek weld. This is not a problem for a one-off hunting shot, but you would not want to spend the day at a PRS match at high mag settings with this scope


I do not notice edge distortion at any magnification with this scope, but the overall lack of clarity at high magnifications will be an issue for some.


The side focus parallax adjustment works well down to 10m and matches well with indicated distances. The knob was easy to grasp and firm to adjust.

The zoom control is well textured and has a raised lever for quick, precise adjustment. It is firm without being stiff and rolls smoothly.

Athlon designed the APMR (Athlon Precision Mid Range) FFP IR MIL reticle for precision long and mid-distance shooting. An illuminated center cross and 0.5 mil hash mark increments can help you quickly lock in your target and set holdover positions and leads for a moving target. 

The illuminated 18 mil span cross lines with 0.5 mil hash marks and 0.2 mil hash marks from 7 to 9 MIL on three directions provide finer details that help a shooter quickly locate the target and find a holdover position with precision and confidence.

This is a busy reticle, but for long-range precision, more is better when it comes to ranging information. The APMR is a FFP (first focal plane) reticle that zooms with magnification and is accurate at all magnifications, unlike sfp reticles which are only valid at max zoom. 

It is clear, crisp, and easy to read even in low light conditions. The fast-focus eyepiece brings it into sharp focus in a hurry. I find it a step up from a regular BDC reticle.


Other reviews and blogs have said a lot about the “poor” feel of the Athlon turrets. I found nothing objectionable about them at all. They are easy to manipulate and not mushy. They have a positive click feel, and I had no trouble at all returning to zero or counting clicks.

On the range, the turrets tracked well at .1 mil increments. I ran the turrets to their ± limits in windage and elevation, and return to zero was perfect.


The Athlon Argos BTR 6-24x50mm features an etched glass reticle with shockproof construction. The main tube is made of 6061 T6 aircraft grade aluminum, o-ring sealed, and argon purged for a waterproof, fogproof, sealed enclosure for added durability. The XPL coating keeps the lenses clear in all weather conditions.

The Athlon positive zero stop system allows you to lock down your zero position and dial back to it with a sharp and precise stop right at your zero mark, even if you are turning it by feel alone.

The fully multi-coated lenses give good color rendition and clear image at all but the highest magnifications. The scope comes in at a healthy weight of 30.3 ounces. If I have to go mountain climbing with this 9+ lb beast (gun, scope, rings, ammo, and sling), I’ll hire a sherpa to carry it for me.


EYE RELIEF WARNING: (Really) The Athlon Argos BTR 6-24x50mm has a modest 3.3 inches of eye relief with a narrow eye box. If you use this scope on magnum, ultra-magnum, or other high-recoil guns with poor shooting technique, there is the possibility of scope impact with the face. Shooters must establish positive control of the gun, good cheek weld, and precise eye alignment to prevent injury.

OK, I’ve done my part. That said, I have not had any problems shooting the heaviest 300 Ultra-Mag loads with this scope. Just don’t get sloppy, and you’ll be fine.

The illuminated reticle has 11 brightness levels and is visible in all lighting conditions. Parallax and zoom showed no point-of-impact shift on the bench. All controls functioned as advertised.
