Overview
Stepping up from the BTR line, Athlon's Ares ETR GEN2 (model 212113) is a 4.5-30x56mm first focal plane rifle scope built with UHD glass to cut chromatic fringing at high power.
UHD glass is Athlon's step up from standard HD glass, meant to cut the color fringing that shows up at high magnification, which matters most at the 30x top end of this scope's range. The GEN2 update keeps the Ares line's illuminated etched reticle and zero-stop turret, and adds lockable turrets to guard against accidental changes while carrying or handling the rifle. Athlon markets it across hunting and precision long range competition use.

Who it's for
This scope earns its keep with hunters and long range competition shooters pushing toward the 30x top end who want a 56mm objective and locking turrets. Shooters who rarely dial past moderate power will not notice much benefit from the UHD glass.
What buyers say
From Amazon customer reviews.
The one review on record praises the scope's clarity, noting it stayed sharp even with the scope set to full power.
Strengths and trade-offs
Drawn from this product's published specifications.
- UHD glass reduces chromatic fringing at high power
- 4.5-30x zoom with 56mm objective
- Lockable turrets protect zero setting
- First focal plane reticle scales with magnification
- 56mm objective adds bulk versus smaller-objective scopes
- High top-end magnification needs a stable rest to use well
Performance notes
At the top of its 4.5-30x range through a 56mm objective, UHD glass is what keeps color fringing down, according to Athlon's design goal for this line. The illuminated reticle sits on the first focal plane so it scales correctly at any power, and the zero-stop turret pairs with a lock to hold a set zero and block accidental dial changes.
