Overview
A first focal plane rifle scope from Athlon Optics with extra low dispersion glass and an illuminated reticle. Built for hunters and precision shooters who want the reticle to scale accurately with magnification changes.
Because it's a first focal plane (FFP) design, the reticle grows and shrinks with the zoom level, so holdover marks stay accurate at any magnification instead of only at one fixed power. The reticle is etched directly onto the glass rather than printed on a floating lens, which Athlon positions as a durability advantage. Extra low dispersion glass is aimed at reducing color fringing around targets in bright conditions.
- First focal plane reticle scales with zoom
- Illuminated reticle for low light
- Extra low dispersion (ED) glass
- Reticle etched on glass for durability
Who it's for
Fits shooters who dial magnification often and want their holdover reticle to remain correct at every setting, a common need in precision rifle competition and variable range hunting. Someone who sets one power and leaves it there gets less benefit from the FFP design specifically.
Pros and cons
- First focal plane reticle stays accurate at every magnification
- Illuminated reticle for low light hunting hours
- Extra low dispersion glass targets color fringing
- Reticle etched on glass rather than printed
- Listing doesn't specify magnification range or objective lens size
- No included accessories mentioned in the specs
Performance notes
The illuminated reticle is intended to stay visible in dusk and dawn light, when a plain black reticle can disappear against a dark background. Etching the reticle onto the glass itself, rather than printing it on a separate element, is meant to hold up better to the recoil and handling a hunting rifle sees over years of use.
