SME XSIBL270W Sight-Rite Laser Bore Sighting System WSM Calibers

The SME XSIBL270W Sight-Rite Laser Bore Sighting System eliminates guesswork when zeroing optics on WSM chambered rifles. This precision laser bore sighter fits 270 WSM, 7mm WSM, 300 WSM, and 325 WSM chambers, providing accurate reference alignment before heading to the range.

What Makes This Different

Unlike universal bore sighters that require adapters, this system features a machined brass casing specific to WSM cartridge dimensions. The precision-fit design ensures consistent alignment with the bore centerline, reducing initial zeroing shots by up to 75%. Class IIIA laser visibility extends to 100 yards in daylight conditions, while the brass construction withstands repeated chambering cycles.

Key Features

• Machined brass casing matches WSM cartridge specifications for precise chamber fit
• Class IIIA red laser projects visible dot to 100 yards in daylight
• Compatible with 270 WSM, 7mm WSM, 300 WSM, and 325 WSM chambers
• Activation button positioned for easy operation while rifle is shouldered
• Durable brass construction resists deformation from repeated use
• Compact design stores easily in range bag or gun case
• Battery-powered operation with extended runtime for multiple zeroing sessions

Range testing shows this bore sighter reduces initial scope adjustment time by placing first shots within 3 inches of point of aim at 25 yards. The system proves valuable for hunters mounting new optics, competition shooters switching between rifles, and anyone installing backup iron sights. Weather-resistant construction handles field conditions, while the brass casing maintains dimensional stability across temperature ranges.

Technical Specs
