Option 1 - Universal .223 Option, Most Affordable Option
.223 Laser Ammo Cartridges
A laser training cartridge is a cross between a snap cap and a bore sighter. It gives you the best of both worlds with only a few minor draw backs. It is the ideal solution for most shooters interested in laser Dryfire training.
The laser training cartridge only engages when the firing pin puts pressure on a pressure point at the back of the cartridge, when this happens, a laser is emitted for a fraction of a second, usually 1/30th of a second. This saves on batteries (this type of device is usually good on batteries for up to 6,000 shots). It also allows the trigger to be engaged (as it protects the firing pin like a snap cap). These are a great solution for using laser Dryfire training software as it best simulates a real life hit on a target. They also typically come zeroed, so there shouldn't be manual adjustments needed out of the box.
Note, on the AR-15, because of the mechanics of the AR-15 you'll need to rack the bolt carrier group between shots to reset the trigger and firing pin. There are better solutions for AR-15s outlined below that are also much more expensive (4 to 5 times more expensive), but this is really the only option if you have a non AR-15 .223 platform.
- Lots of options for any budget
- Battery efficient
- Most realistic solution
- Easy setup, shouldn't need to be zeroed
- Protects firing pin from damage like a snap cap
- Useful for reloading drills as it won't eject, but it should not be fed from a magazine
- Works with any .223 Caliber Weapon
- BCG must be racked each time in an AR-15 unlike other more expensive products
- The back caps on these will go bad over time with heavy use as the firing pin slams the pressure pad repeatedly (some products offer replacement back caps for sale). The back caps are usually good for thousands of dry fires however.
