Frequently Asked Questions
Is the BSA Sweet 17 scope only compatible with .17 HMR rifles?
The BSA Sweet 17 is specifically calibrated for the .17 HMR cartridge using a 17-grain bullet, and its ballistic turret is matched to that load's trajectory. While the optic itself can physically be mounted on other rimfire platforms, you'll get the full benefit of the calibrated turret system only when shooting .17 HMR. For other calibers, a different Sweet series scope — such as the Sweet .22 — would be the more appropriate choice.
What does the adjustable objective (AO) do, and why does it matter for .17 HMR shooting?
The adjustable objective allows you to fine-tune the scope's parallax setting for your specific shooting distance. Parallax error can cause the reticle to appear to shift relative to the target when your eye moves off-center, leading to inaccurate shots. For .17 HMR shooting — where flat trajectories and small targets demand precision — eliminating parallax at your intended range is crucial for consistent, repeatable accuracy.
What type of mounting system does this scope use, and will it fit my rifle?
The BSA Sweet 17 comes with 2-piece dovetail rings, making it compatible with rifles that feature a standard 3/8-inch or 11mm dovetail rail — the most common mounting system found on rimfire rifles. If your rifle has a Picatinny or Weaver-style rail instead, you may need to purchase separate compatible rings. Always verify your rifle's rail specification before mounting to ensure a proper fit.
