BSA Sweet 17 6-18x40mm Rimfire Rifle Scope with Side Focus & Duplex Reticle - Matte Black

The BSA Sweet 17 6-18x40mm rimfire rifle scope is purpose-built for .17 HMR hunting and precision shooting. This matte black scope pairs a versatile 6-18x magnification range with a 40mm objective lens—a practical balance for varmint hunters and rimfire enthusiasts who need both wide-field acquisition at closer ranges and enough zoom for distant targets. The side-focus parallax adjustment (10 yards to infinity) lets you dial out image blur at any distance, critical when you're shooting small game or steel at the range.

The standout feature here is the dual-ring zoom mechanism: the outer ring rotates to change magnification, while the inner drum stays fixed with a window cutout that always faces you. This design keeps your parallax markings visible and readable without rotating out of view—a smart touch for hunters who need to make quick adjustments in the field. The scope comes pre-configured with turret drums calibrated for .17 HMR ballistics, so you're not starting from scratch when dialing elevation and windage.

At 17.6 ounces, the Sweet 17 won't burden a lightweight rimfire rifle, and the 4-inch eye relief plays well with most shooting positions. The duplex reticle is an old-school choice—simple, fast to use, and reliable in any light. This is a no-frills optic designed for hunters and shooters who want proven glass and honest adjustments without the premium price tag.

Frequently Asked Questions

Is this scope calibrated for .17 HMR out of the box?

Yes. The turret drums come pre-calibrated for .17 HMR ballistics, so you can start zeroing and dialing without guessing.

Can I use this scope on other rimfire cartridges?

The scope itself will mount on any rimfire rifle with standard scope rings. However, the pre-calibrated drums are specific to .17 HMR; if you shoot a different cartridge, you'll need to establish your own zero and elevation holds.

How does the fixed inner-ring zoom design work?

The outer ring rotates to change magnification, while the inner drum with the window cutout stays fixed and always faces you. This keeps your parallax adjustment markings visible and easy to read without having to rotate the scope to find them.

What's the parallax range, and do I need to adjust it often?

The parallax adjustment ranges from 10 yards to infinity. For varmint and small-game hunting, you'll likely adjust it whenever your shooting distance changes significantly—especially when transitioning from close-range to long-range targets.
