Sightmark SM39004 Laser Boresight .264/7mm/.338 Cal Brass

The Sightmark SM39004 is a chambering-style laser boresight built for hunters and long-range shooters who want to get on paper quickly without burning through live ammunition. Simply chamber the boresight in your rifle like a regular cartridge and a bright red laser dot shows exactly where the barrel is pointing, eliminating the trial-and-error of sighting in a scope with live rounds.

This model is specifically sized for .264, 7mm, and .338 caliber rifles, covering popular hunting chamberings such as the 7mm Remington Magnum, .264 Winchester Magnum, and .338 Winchester Magnum. The cartridge-shaped body is machined from durable brass so it mimics the dimensions of a loaded round and chambers reliably in any rifle of the appropriate caliber, with no modifications required.

The unit is powered by three AG3 button-cell batteries and ships with its own battery pack along with a protective carrying case for safe transport to and from the range. Compact, lightweight, and easy to pack with your other range gear, the SM39004 is one of the fastest ways to reduce wasted cartridges and get your scope dialed in on the first trip out.
