Aimshot BSB17 Laser Boresighterwith External Battery Box 17 HMR Brass

The Aimshot BSB17 laser boresighter is a chamber-insert boresighting tool designed specifically for .17 HMR rifles. Instead of shooting rounds downrange to dial in your scope, a laser boresighter lets you align your optic to the rifle's barrel axis from a bench or rest, saving ammunition and time during setup. The BSB17 uses an external battery box, which means you can keep fresh batteries handy and swap them without fumbling inside the rifle.

This is a solid choice if you're building a new .17 HMR or simply need to re-zero an established rig before heading to the range or field. Because it's caliber-specific (17 HMR), it seats precisely in the chamber, giving you a reliable laser point of reference. The external battery design also makes it easier to check battery status and power the laser on and off without disassembly.

Boresighting is not a substitute for live-fire zeroing—it gets you on paper quickly so your first shots count—but many hunters and shooters appreciate cutting down wasted ammunition during the initial setup phase. The Aimshot brand has long been recognized in this category, and the BSB17 delivers the straightforward functionality you need to align your scope without guesswork.

Frequently Asked Questions

What caliber is the Aimshot BSB17 designed for?

The BSB17 is chambered for .17 HMR rifles only. Do not attempt to force it into a different caliber chamber.

How does an external battery box help during boresighting?

The external battery compartment allows you to power the laser on and off, and swap batteries, without removing the boresighter from the rifle's chamber. This streamlines the setup process and makes it easy to check battery condition.

Is a laser boresighter enough to zero my scope?

A laser boresighter aligns your scope to the barrel's axis and gets you close to zero, but it is not a replacement for shooting live ammunition and making final adjustments at your intended distance. Always confirm zero at the range before hunting or competition.
