Classic Firearms+1

20X Brighter Red Laser – Superior Visibility & Longer Range
The standout feature of this model is right in the name: 20X brighter than Aimshot’s standard boresighter. Classic Firearms+1
That extra brightness delivers real-world benefits:
Easier to see in daylight and well-lit indoor ranges
Sharper, more defined laser dot at typical bore-sighting distances
Effective from 3 yards out to around 100 yards, depending on lighting and target surface cheaperthandirt.com
Ideal for shooters who want to set up or verify a zero in bright outdoor conditions
The laser uses a 632 nm red wavelength with output power under 5mW (Class IIIa), giving you a highly visible dot while staying within safe consumer laser limits. cheaperthandirt.com+1
Cartridge-Style, Chamber-Mounted Boresighter
The BS22320X drops into your chamber just like a live round:
Cartridge design precisely mimics a .223 Rem case for consistent alignment in the chamber Classic Firearms+1
Chamber-mounted setup means the laser is aligned with the true centerline of your bore, not just the muzzle
No special tools required—simply insert, close the action, and you’re ready to adjust your optics
Because it indexes off the chamber, this style of boresighter tends to offer very repeatable alignment between rifles, making it perfect for shooters with multiple AR-15s or .223 bolt guns.
Built from Brass – Durable, Precise, and Barrel-Friendly
Aimshot builds the BS22320X from solid brass, the same material used in quality cartridge cases:
Consistent fit in the chamber for reliable, repeatable pointing
Durable construction that can handle frequent insertion and removal across multiple rifles battlehawkarmory.com+1
Brass is naturally softer than barrel steel, making it gentle on your chamber and extractor
The result is a rugged boresight that’s built to last, whether you’re using it for an occasional optic swap or constant use in a gunsmithing shop.
Designed for .223 Rem & 5.56 NATO – Core of the Aimshot System
The BS22320X is tailored specifically for .223 Remington and 5.56x45mm NATO chambers. cheaperthandirt.com+1
Key compatibility details:
Primary caliber: .223 Rem / 5.56 NATO (AR-15, many bolt actions, and other rifles)
Acts as the core laser module for Aimshot’s modular boresight system
With additional Aimshot arbors (sold separately), you can bore sight many other calibers using the same .223 laser module—making it a powerful multi-caliber solution Classic Firearms+2battlehawkarmory.com+2
Instead of buying a separate boresighter for every rifle, you invest once in this 20X brighter .223 laser and expand with affordable arbors as your collection grows.
Save Time and Ammo When Zeroing Optics
Using the Aimshot BS22320X can dramatically streamline your sight-in process:
Ensure the firearm is unloaded and safe.
Insert the brass boresighter into the chamber.
Aim at a target 15–25 yards away.
Adjust your scope, LPVO, or red dot so the reticle lines up with the laser dot. Ammunition Depot+1
Remove the boresight and confirm with a few live rounds at your desired zero distance (e.g., 50 or 100 yards).
Because the rifle is already “on paper,” you’ll typically need fewer rounds to achieve a perfect zero—saving both time and money, especially when using premium ammo.
Powered by LR41 / L736 Batteries – Ready for the Bench or Range
The BS22320X runs on compact button cell batteries:
Uses three LR41 / L736 button cells, commonly available and inexpensive Classic Firearms+1
Typical battery life is around 20 minutes of continuous use, plenty for multiple rifles in a single session cheaperthandirt.com+1
Batteries are easy to replace, so you can keep the boresighter ready to go in your range bag at all times
Because bore sighting only takes a few minutes per rifle, a single set of batteries goes a long way.
Ideal for New Builds, Optic Swaps, and Multi-Rifle Owners
The Aimshot 20X Brighter .223 Brass Laser Boresighter is especially valuable if you:
Build or reconfigure AR-15s and need to mount and zero optics frequently
Own multiple .223/5.56 rifles and want consistent, repeatable bore sighting
Swap scopes or red dots often and want a quick way to get back on target
Run a gunsmith shop, training business, or department armory, where zero checks are routine
Instead of guessing where your first shots will land, you start with a solid, laser-guided baseline.
Compact and Easy to Carry
With its small cartridge footprint, the BS22320X can live almost anywhere:
Tucks easily into range bags, pouches, or rifle cases
Perfect for keeping in a field kit to re-check zero after travel or rough handling
Handy for quick diagnostic checks if a rifle suddenly starts grouping off-target
It’s an always-ready tool that solves a common problem in just a few seconds.
