UHD Glass Extra-Low Dispersion glass significantly reduces chromatic aberration giving you an utmost bright and sharp image with true color reproduction.
Illuminated Reticle The illuminated reticle provides greater visibility during dusk and dawn and other low ambient light environment.
First Focal Plane Reticle First focal plane reticle stays valid at all power settings allowing you to fully utilize the specially designed reticle that shrinks or grows along with your target as you zoom in or out. The reticle offers quick target engagement at low power while offering precise holdover positions with finer details.
Etched Glass Reticle Reticle etched on the glass that provides excellent backing support for complex reticle design and offers great durability and much higher shock resistance to recoil
Advanced Fully Multicoated Fully Multicoated optics effectively reduces reflected light and increases the transmission of light giving you a brighter image than normal single coated lenses
XPL Coating XPL Coating gives you an extra protection on the exterior lenses from dirt, oil and scratches or anything else mother nature can throw at you.
Precision Zero Stop System The 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 you are turning it in pitch-dark or blind folded.
High Precision Erector System The high precision erector system processed by high precision CNC machine with +/- 0.0001mm tolerance level to provide you the most accurate power settings and smoothest magnification change
6061 T6 Aluminum The 6061T6 aircraft grade aluminum tube that has exceptional strength and superior mechanical integrity will protect these world class optics no matter what punishment you throw at it.
Exposed Tactical Direct Dial Exposed Direct Dial Turrets for elevation and windage allow you to quickly make adjustment as you needed and engage your target within a blink of your eyes
One Piece Tube Construction Heat treated one piece tube gives the scope extra strength over multi-piece tubes. A one piece tube also is better at keeping moisture out thus keeping your scope fog proof for the life of the product
Waterproof Waterproof to protect the scope in the harshest weather conditions or if accidently submerged underwater
Fog proof Fog proof to allow you to immediately engage your target when you take your rifle to cold ambient temperature from warm inside
Shockproof Robust mechanical system with special designs on both control and erector system that give you the ultimate recoil resistance to withstand 1000G recoil for 1000 times.
Argon Purged Argon Purging uses the inertia gas with bigger size molecules to purge any moisture out of the tube giving you better waterproofing and thermal stability .

    Purchased this scope for long range and precision rifle competitions and have been extremely pleased with it’s performance. It is well made, sturdy and the glass is outstanding. It has gone through a lot of abuse and has never let me down. I did manage to break an elevation knob-my fault, contacted Athlon for a replacement and offered to pay for a new knob and postage after explaining what happened. Athlon graciously covered the cost of the replacement and postage. Although only one instance, Athlon customer service is amazing in my book. Based on the quality and performance of their products, I will remain a loyal Athlon customer.

    I SO wanted to give this scope 5-stars, and only one tiny issue is stopping me.

    Once mounted and working correctly, this scope is AWESOME and cheaper than the rest of the world by “hundreds”. Glass is super clear, reticle is great, and controls track flawlessly. Bought this to shoot my Masterpiece Arms 300 Win Mag out to a mile, and it’s a terrific value and compares favorably to much more expensive glass.

    BUT … my initial experience was awful and so frustrating, until I figured it out. Pay attention, because this could be important if you buy this scope.

    I unboxed, unwrapped and the only “assembly” per se is to remove the illumination battery cover, insert the battery, and screw the cap back on. No big deal … right? WRONG! I removed the batter cover, it was tight, but not unreasonably tight since it’s o-ring sealed. I inserted the battery, and spent the next two days of my holiday weekend desperately trying to screw the cap back on. The threads simply wouldn’t engage, and it would just spin and drop off. Drove me “nuts” until I accidentally figured it out.

    I was near the end of my rope, having tried everything I could think of. My last attempt was to use a dental tool (tiny end) and a magnifying lamp (lousy vision) to follow and clean out both thread patterns to see if there was something blocking them, or perhaps a cross-thread. Here’s where the epiphany took place. As I was nearing the end of the threads in the battery compartment, my tool “fell” into a tiny plastic slot adjacent to what appeared to be the threads … and the plastic MOVED.

    Long story short (sorry … it’s already long), that plastic ring is how the interior electronics is exposed/removed/serviced. All I did was take my little dental tool, and turned that plastic ring on the threads to a solid stop, exposing several more rings of threads. Then the battery dropped in, the cap threaded perfectly, illumination worked fine, and the scope was officially healed. Mounted and aligned just like it should … ready to shoot.

    And since I’m an Engineer …

    Symptom: Battery compartment cap will not screw in correctly after replacing illumination battery – cap spins without engaging the compartment threads.

    Root Cause: Manufacturing (or human) error where the electronics keeper ring was not sufficiently tightened to keep it from threading out when the battery compartment cap is removed.

    Corrective Action: Use a jewelers screwdriver or some other very small tool and use one of the two notches in the plastic keeper ring to screw it all the way down to the base of the threads.

    Here endeth the lesson … the initial relationship started badly, but I think now we’ve fallen in love. Without that issue (described above) … it’s a 5-star scope all day long – twice on Sundays.
