The Firefield In-Chamber Red Laser Brass Boresight for .223 Remington is a fast, no-guesswork way to get your rifle sighted in without burning through ammunition. Drop it straight into your chamber, and a bright red laser shows you exactly where your barrel is pointed—turn that into your aim point using your scope or iron sights, and you're ready to head to the range or field. It cuts the tedious back-and-forth of traditional bore sighting and lets you dial in your zero indoors or at close distance, then use live fire only to verify and fine-tune for distance, wind, and bullet drop.
Built from brass for durability, this bore sight is compact and lightweight enough to toss in a range bag or pack. The included pair of AG5 batteries will run the laser for roughly an hour of use, so you've got plenty of juice for a solid sighting-in session. Whether you're preparing a hunting rifle or dialing in a precision target gun, this tool saves ammo, time, and frustration by eliminating the guesswork from initial sight alignment.
This is the kind of accessory that pays for itself the first time you use it—especially if you're working up loads, testing new scopes, or helping someone else get their gun on zero. Red laser bore sights have become the standard for shooters who want to be efficient at the bench and confident in the field.

A laser bore sight is a tool that sits in your rifle's chamber and projects a laser dot down the barrel to show you where the gun is pointing. You use that dot as a reference to align your scope or sights mechanically, which gets you close to zero without needing to fire a lot of rounds. Live fire is then used only to fine-tune for bullet drop and wind drift at actual distance.
Yes—this bore sight is chambered for .223 Remington and inserts directly into your rifle's chamber. Simply drop it in, turn it on, and you're ready to sight in.
The bore sight uses two AG5 batteries, which are included. Each pair will run the laser for approximately one hour of use.
A laser bore sight works best in lower-light conditions where the dot is clearly visible. You can use it indoors, in dim light, or outdoors in shade. In bright daylight or at distance, the dot becomes harder to see, so most shooters use bore sights during initial zeroing and then confirm with live fire at range.
