Firefield FF39000 Red Laser Universal Boresight for Multi-Caliber Firearms

A red laser boresighter is one of the fastest ways to get your rifle on target without wasting ammunition or time at the range. The Firefield FF39000 Red Laser Universal Boresight is designed to work across multiple calibers, making it a practical tool whether you're zeroing a .22, a magnum, or anything in between. Instead of firing rounds downrange to dial in your scope, you simply insert the boresighter into the barrel, activate the laser, and align your reticle to the dot on a distant target or wall. It's a workflow that saves ammo, reduces frustration, and gets you shooting accurately in minutes.

Boresighting is especially valuable when you're setting up a new rifle, swapping scopes, or making a major change to your rifle setup. Rather than start your zero completely blind, a laser boresighter gives you a solid mechanical reference point—a huge head start before you ever fire a shot. The universal design means you don't need to buy a different tool for each caliber in your safe, and the red laser wavelength (632–650 nM) is bright enough to spot indoors or in low light without requiring complicated setup.

This is a staple tool for hunters, sport shooters, and range regulars who value efficiency and accuracy. Once you use a quality boresighter, you'll wonder how you ever zeroed a rifle without one.

How do I use a laser boresighter?

Insert the boresighter into the barrel, activate the laser, and aim it at a target (wall, paper, or distant object). The laser dot shows where your bore is pointed; align your scope reticle to match that dot. This gives you a rough zero before live fire, saving ammunition and time at the range.

Can I use this indoors?

Yes. The red laser wavelength is bright enough to be visible indoors or in low light, making it practical for garage or shop setup and alignment.
