- First focal plane reticle scales with zoom
- UHD extra-low-dispersion glass
- Locking elevation turret
- Waterproof, fully multicoated optics
Who it's for
Suits rifle shooters, including AR-10 and precision builds, who want an FFP reticle for ranging across zoom levels. Less relevant to shooters who only ever use a scope at one fixed magnification.
What buyers say
From Amazon customer reviews.
Reviewers describe the glass as crisp and clear, with one calling it a noticeable step up from a Vortex Strike Eagle and another reporting sub-MOA groups at 300 yards on an AR-10. The main complaint is that illumination isn't daylight-bright and that Athlon doesn't sell matching scope caps, though owners still call it a strong value at its price point.
Strengths and trade-offs
Drawn from this product's published specifications.
- FFP reticle stays accurate across zoom range
- Reliable return-to-zero reported by reviewers
- Locking elevation turret guards against bumps
- Illumination not daylight-bright per one reviewer
- No factory scope caps available from Athlon

Questions about the Optics 212105
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
What does first focal plane mean on this scope?
The reticle grows and shrinks with the target as you zoom, so holdover and ranging marks stay accurate at any magnification.
Does the Athlon Ares ETR come with scope caps?
No, one reviewer notes Athlon doesn't offer matching caps and used a Butler Creek alternative instead.
Is this scope waterproof?
Yes, it's built to be waterproof for use in wet conditions or accidental submersion.
