The BSA 1739X40AO Sweet 17 Black Matte 3-9x 40mm AO Rifle Scope is purpose-built for .17 HMR rimfire shooters who want simple, repeatable elevation adjustments in a compact package. Its 3-9x magnification range, 40mm adjustable objective, and 1 inch tube combine to deliver a clear sight picture with generous 3 inch eye relief, while the 30/30 duplex reticle keeps the view uncluttered for small-game and target work. Fully coated or fully multicoated lenses and fogproof, shockproof, waterproof construction help maintain clarity and reliability in changing conditions.

This Sweet 17 scope features side or adjustable objective parallax correction from as close as 7.5–10 yards out to infinity, plus an elevation turret ballistically calibrated for common 17 grain and 20 grain .17 HMR loads. Included dovetail rings provide an out-of-the-box mounting solution for many rimfire rifles, making it a practical choice for hunting varmints, small game, or casual range use. BSA’s Sweet series reflects the brand’s focus on accessible optics that blend thoughtful ballistic features with dependable performance.
