Overview
A 3-12x40 rifle scope built specifically for the .17HMR, with an elevation turret calibrated for 17 grain and 20 grain bullets and fully multi-coated optics.
BSA built this scope around one cartridge rather than as a general purpose optic, and reviewers who paired it with .17HMR bolt guns like the Savage 93 confirmed the turret's grain specific calibration tracks true. A few buyers ran into stuck lens caps or a failed bullet compensator on early units, though most reports describe clear glass and accurate turret adjustments holding up over repeated use.
- 3-12x40 magnification range
- Turret calibrated for 17gr/20gr .17HMR
- Fully multi-coated optics
- Waterproof, shockproof, fogproof
Who it's for
Owners of .17HMR rifles who want a dedicated, grain calibrated scope rather than a general variable power optic. Not the right choice for other calibers, since the turret is specifically tuned for 17 and 20 grain .17HMR loads.
What buyers say
From Amazon customer reviews.
Most reviewers who mounted this on .17HMR rifles like the Savage 93 praised the clear glass, accurate quarter inch clicks and grain specific turret calibration. One buyer went through three units due to stuck lens caps and a failed bullet compensator before giving up on the product.
