• Precision-machined brass chamber cartridge fits the chamber like a dummy round for a stable fit
• High-output laser projects through the muzzle to align scope or iron sights without firing
• Factory-aligned laser: ready to use with no on-site adjustment
• Batteries included — operational straight from the box
• Ideal for zeroing preparation on stalking calibres before a range session

The SME Sight-Rite Chamber Cartridge Laser Bore Sighter covers three popular stalking and target calibres — .243, .308 Winchester and 7mm-08 Remington — in a single precision-machined brass chamber cartridge. It seats directly into the rifle's chamber like a dummy round, providing a stable, wobble-free platform that avoids the inconsistency of muzzle-insert bore sighters. A high-output laser beam projects down the barrel, letting the shooter align a riflescope or open sights to a target at zeroing distance without firing a shot. The laser is factory-aligned and ready to use without adjustment, and batteries are included. For stalkers switching between a rifle that has been cleaned down or one with a freshly fitted scope, the Sight-Rite reduces the number of rounds needed to achieve a working zero considerably. The three calibres share the same parent brass case dimensions, making a single unit suitable across all three chamberings.
