Description
Dry fire practice and bore sighting usually mean two separate tools, but LaserLyte built both into one brass cartridge chambered for .223 Remington and 5.56 NATO. It drops right into the chamber of your unloaded rifle and lines up with the bore, no gunsmithing or funky adapters required. The trick is a pair of swappable end caps: one turns it into a laser trainer, the other into a bore sighter. Pop the cap you need and you are set.
What the Two Caps on This 223 Laser Cartridge Actually Do
The laser trainer cap is firing pin activated. Every time your hammer or striker drops, it flashes a red laser for about a tenth of a second right where the bullet would land. That instant feedback is gold for diagnosing flinch, trigger jerk, and follow through, and it pairs with the full lineup of LaserLyte reactive targets for interactive at home drills. Swap over to the bore sight cap and the laser runs constant on, giving you a steady reference point to rough in a scope, red dot, iron sights, or laser before you ever spend a round confirming zero at the range.
Built to Take a Beating in Your AR or Bolt Gun
A built in rubber snap cap cushions the firing pin, so you can rack and dry fire again and again without beating up your gun. The 5mW Class IIIA red laser stays bright and easy to pick up indoors, and the internal batteries come installed and are good for around 3,000 shots before they need a swap. When you are done, a cleaning rod gently pushes it back out of the chamber.
A Smart Training Buy for AR-15 and 5.56 Owners
Works great in AR platforms and bolt actions alike. Just run it without a magazine in a semi auto so nothing tries to strip or eject it. Whether you are coaching a new or younger shooter on shot placement or keeping your own fundamentals sharp in the off season, this cartridge earns its spot in the range bag.

Frequently Asked Questions
Can I use this 223 laser cartridge in an AR-15 or just bolt guns?
It works in both AR platforms and bolt action rifles chambered in .223 Rem or 5.56 NATO. In a semi auto, run it with no magazine inserted so the action does not try to strip or eject the cartridge. It fits in the chamber like a normal round and pushes out with a cleaning rod when you are finished.
What is the difference between the two end caps?
The laser trainer cap is firing pin activated and flashes a red dot for about a tenth of a second each time you dry fire, showing your point of impact for drills and reactive targets. The bore sight cap keeps the laser constant on for a steady reference while you zero a scope, red dot, or iron sights. You simply unscrew one cap and thread on the other depending on what you are doing.
How long do the batteries last and are they included?
The batteries come installed from the factory, so it is ready to use out of the package. You can expect around 3,000 activations before they need replacing. That is a lot of dry fire reps before you ever have to think about swapping cells.
Will the laser trainer work with LaserLyte targets?
Yes, the firing pin activated trainer cap is designed to work with the full line of LaserLyte reactive and electronic targets. That turns basic dry fire into an interactive session where you can track hits, groupings, and trigger control at home. It is a great setup for new shooters learning shot placement.
