The BSA Sweet 17 3-12x40mm rimfire rifle scope brings precision and flexibility to .17 HMR and .20-grain shooters who demand accuracy across varying ranges. Unlike general-purpose rimfire scopes, this AO (adjustable objective) scope includes matched turret drums for both popular .17 HMR and .20-grain cartridges—so you can dial true ballistic compensation instead of holding over. Built for serious hunters and precision rimfire competitors, it pairs a 3-12x magnification range with a compact 40mm objective, making it equally at home on a lightweight hunting rifle or a bench-rest setup.
The illuminated RGB duplex reticle—red, green, and blue glass-etched options—adapts to light conditions, from dim timber to bright-sky shooting. The fully multi-coated optics and 4 inches of eye relief keep your sight picture stable and forgiving. At under 18.5 ounces, weight stays minimal, and the matte-black finish resists glint and corrosion. The adjustable objective eliminates parallax error from 10 yards to infinity, tightening groups at distance and ensuring consistent aim across your shooting session.
Whether you're hunting prairie dogs and coyotes or punching paper at 100+ yards, the Sweet 17 handles the job without the bloat of a hunting scope designed for centerfire cartridges. The 1/4-minute click adjustment and wide 45-minute correction range let you zero cleanly and hold elevation across real-world distance. This is a scope purpose-built for rimfire precision.

Yes. The BSA Sweet 17 comes with matched turret drums for both .17 HMR and .20-grain cartridges, so you can swap drums to dial the correct ballistic compensation for whichever rimfire you're shooting that day.
The reticle is glass-etched and illuminated, and you can select red, green, or blue light to match shooting conditions—red for low light, green for midday glare, blue for overcast skies. This gives you flexibility without needing to change scopes.
The adjustable objective corrects parallax from 10 yards to infinity. As you focus the objective, you're removing the gap between the reticle plane and your target, which tightens groups and ensures the reticle stays true across distance and various shooting positions.
At 18.3 ounces, the Sweet 17 is built for minimal weight. On a typical rimfire hunting rifle, it adds negligible heft and keeps your setup fast and handy in the field.
