GSM Laser Boresight .243/7mm/.308

The GSM Laser Boresight .243/7mm/.308 is a precision alignment tool designed for shooters, armorers, and tactical professionals who demand fast, accurate barrel zeroing without firing a single round. This laser boresight eliminates costly ammunition waste and reduces range time by establishing a preliminary point-of-aim alignment in seconds. Whether you're setting up a hunting rifle, law enforcement duty weapon, or precision tactical platform, this compact device saves both time and money while providing repeatable bore-axis reference data.

Built by GSM, this laser boresight uses a visible laser beam projected from the chamber to identify the true bore axis at distance, allowing shooters to mechanically align optics and iron sights to that reference before live-fire confirmation. The design accommodates .243 Winchester, 7mm Remington Magnum, and .308 Winchester platforms with a single tool, maximizing versatility across your rifle collection. Weighing just 0.17 pounds and measuring 4.1 inches in length, the boresight fits easily into any gear bag or range kit and operates with minimal setup, making it ideal for field-stripping procedures, barrel changes, or quick pre-mission checks.

Law enforcement armorers, military personnel, and civilian precision riflemen benefit most from this tool when transitioning between optics, replacing barrels, or validating zero after transport and storage. Its chambering compatibility spans modern sporting rifles and bolt-action platforms, ensuring that it meets the needs of a variety of users. The GSM Laser Boresight is an essential tool for anyone looking to enhance their shooting accuracy and efficiency.
