Overview
Athlon Optics' Helos BTR GEN2 is a first focal plane rifle scope built around locking elevation and windage turrets, so the reticle holds its dial and resists drifting under recoil or in a pack. It suits hunters and shooters who want to dial for distance rather than hold over.
- First focal plane reticle
- Locking elevation and windage turrets
- Fully multicoated waterproof optics
- Model 214108
Who it's for
Best suited to hunters and precision shooters running rifles like a 6.5 Creedmoor or 300 Weatherby who want a dial-capable optic without premium European glass pricing. Less suited to someone who needs repeatable click-for-click tracking out of the box every time, since at least one unit shipped with erratic adjustments.
Pros and cons
- One buyer's unit had erratic tracking that took close to a dozen rounds to sight in
- Feels heavy on a hunting rifle per one review
Performance notes
The locking turret system requires pulling up to dial and pushing down to lock, which prevents accidental movement in transport. Because the reticle is first focal plane, holdover and ranging marks read true at any zoom setting rather than only at max power.
