The BSA 17312X40AO Sweet 17 Black Matte 3-12x 40mm AO 1" Tube 30/30 Duplex Reticle rifle scope is purpose built for .17 HMR shooters who want clear glass and caliber-matched adjustments in a compact package. Its 3-12x magnification range and 40mm adjustable objective provide a bright, focused sight picture from close rimfire distances out to longer varmint shots, while the elevation turret is ballistically calibrated for popular 17-grain and 20-grain .17 HMR loads.

This Sweet 17 scope uses a 1" main tube, fully coated or fully multicoated lenses, and a non-illuminated 30/30 duplex reticle that keeps the view uncluttered for hunting and target work. Side or adjustable objective parallax correction from roughly 7.5–10 yards to infinity helps maintain a sharp image and precise point of aim, and generous eye relief around 3–4 inches supports comfortable shooting from the bench or in the field. It is a strong fit for small game, varmint hunting, and rimfire range use, reflecting BSA’s focus on practical, value-driven optics for dedicated rimfire platforms.
