Firefield 5.56 In-Chamber Red Laser Brass Boresight

The Firefield 5.56 In-Chamber Red Laser Brass Boresight is a device designed to assist firearm owners in zeroing their rifles or carbines. It is specifically calibrated for the 5.56 NATO/.223 Remington caliber, which is commonly used in AR-15 style rifles.

The purpose of a boresight is to align the firearm’s sights or optics with the bore of the barrel. By doing so, it helps ensure that the bullet’s trajectory matches the point of aim, thus improving accuracy. The Firefield In-Chamber Red Laser Brass Boresight achieves this by projecting a red laser beam down the centerline of the barrel.

One of the key features of this boresight is its design as a brass cartridge-shaped device that fits directly into the chamber of the firearm. This allows for quick and easy installation without the need for any additional tools or equipment. Once inserted, the boresight activates automatically, emitting a bright red laser beam that extends out from the muzzle.

The Firefield In-Chamber Red Laser Brass Boresight is powered by three LR44 batteries, which are included with the product. These batteries provide sufficient power to operate the boresight for extended periods, allowing users to zero their rifles without worrying about battery life.

To use the boresight effectively, firearm owners should follow a specific procedure. First, they need to ensure that their firearm is unloaded and in a safe condition. Then, they should insert the boresight into the chamber and close the bolt or slide. Next, they should align their sights or optics with the projected laser beam on a target at a suitable distance (typically around 25 yards). Finally, adjustments can be made to bring the point of aim in line with the laser beam.

It is important to note that while using a boresight can help with initial zeroing, it does not replace live-fire testing at longer distances. Once the boresight has been used to align the sights or optics, it is recommended to confirm the zero by shooting at various distances and making any necessary adjustments.

In conclusion, the Firefield 5.56 In-Chamber Red Laser Brass Boresight is a useful tool for firearm owners looking to zero their rifles or carbines chambered in 5.56 NATO/.223 Remington caliber. Its brass cartridge design allows for easy installation, and the red laser beam helps align the sights or optics with the bore of the barrel. However, it is important to remember that live-fire testing is still necessary to confirm the zero.
