Aimshot BS223 Laser Boresighter Cartridge 223 Rem Brass

Before you dial in your .223 rifle scope, a laser boresighter eliminates wasted rounds and gets your zero faster. The Aimshot BS223 chamber-loaded design works by inserting directly into your magazine well, projecting a laser dot onto your target at range. Whether you're sighting in near San Leandro or anywhere in Northern California, proper bore alignment starts here.

Chamber-loaded laser alignment for .223 rifles

The cartridge-style boresighter seats directly in your .223 chamber without tools or modifications. Once seated, the laser projects a reference point downrange, letting you adjust scope elevation and windage before firing live rounds. This method saves ammunition and accelerates your zero process on the range. For California shooters managing multiple firearms or preparing for your first build, understanding alignment tools matters.

Frequently asked questions

Will this boresighter work in both .223 Remington and 5.56 NATO chambers?

Yes. The BS223 is designed for both .223 Remington and 5.56 NATO chambers since they share the same cartridge dimensions. The laser reference remains consistent across both caliber designations.

How do I safely insert and remove the boresighter from my rifle?

Unload your rifle completely, lock the bolt open, and insert the boresighter cartridge into the chamber like you would a live round. Close the bolt gently to seat it. Remove by opening the bolt and pulling the cartridge straight out. Always confirm your firearm is unloaded before handling.

How long is the California firearm waiting period?

California requires a 10-day waiting period from when DROS is submitted until you can take possession of the firearm. Looking for FFL dealer Menlo Park? Visit us in Sunnyvale.
