Athlon Ares ETR Gen 2 UHD Rifle Scope 1-10x24 34mm FFP ATMR3 MIL Illum. Black

The Athlon Ares ETR Gen 2 UHD 1-10x24 rifle scope is a versatile first focal plane optic built for shooters who demand flexibility—whether you're engaging targets at 25 yards or stretching shots out to 700. The illuminated ATMR3 reticle is purpose-built around 223 Rem/5.56mm NATO ballistics (68 and 69-grain BTHP), though it remains compatible with a variety of other bullet weights and calibers, making it a practical choice for AR platform shooters and precision rifle enthusiasts who might load different ammunition.

At 1X magnification, the illuminated center horseshoe functions like a red dot—daylight-bright and fast-acquiring for close-range work. As you dial up magnification, the BDC hash marks reveal themselves, providing ballistic holds at 100-yard increments from 300 to 700 yards. The reticle also includes dedicated wind correction marks for 5 and 10 mph drift, letting you make holdover adjustments without spinning turrets. A ranging tree on the lower vertical post gives you a quick way to estimate distance on a 36-inch silhouette target, a practical feature for field situations where speed counts.

The 34mm tube and first focal plane design keep the reticle scaled to magnification, so those BDC marks stay true no matter where you land on the power ring. This is the scope for a shooter who wants one optic to handle multiple mission profiles—close defensive work, mid-range training, and longer shots—without compromise.

Frequently Asked Questions

Will this scope work with calibers other than 223/5.56?

The ATMR3 reticle is designed specifically for 223 Rem/5.56mm NATO ammunition (68 and 69-grain BTHP), but Athlon notes it is compatible with many other bullet weights and calibers. However, the ballistic holds are optimized for that cartridge, so performance with other rounds may vary.

How does the reticle function at low magnification?

At 1X magnification, the illuminated center horseshoe is designed to work like a red dot sight—fast and intuitive for close-range engagements. As you increase magnification, the BDC hash marks and additional reticle details become visible for longer-distance work.

What is the ranging tree used for?

The ranging tree on the lower vertical post allows you to quickly estimate distance on a standard 36-inch tall silhouette target. This helps you dial in the correct hold without needing external range-finding tools.

What makes first focal plane better for this type of scope?

With the reticle in the first focal plane, the BDC marks remain proportional to your target at any magnification level. This means your holdover corrections and wind marks stay true whether you're at 1X or 10X, eliminating the guesswork that comes with second focal plane designs.
