Sightmark SM39001 Red Laser Boresight .223 Rem 5.56 NATO Brass

The Sightmark SM39001 boresight eliminates the guesswork from rifle zeroing by providing precise laser alignment before firing a single round. This red laser boresight fits .223 Remington and 5.56x45mm NATO chambers, allowing shooters to establish initial zero at the range or in the field without wasting ammunition.

What Makes This Different

Unlike basic boresights that require manual activation, the SM39001 features an integrated battery pack system that delivers consistent power output throughout the zeroing process. The precision-machined brass construction ensures exact chamber fit without the wobble common in plastic alternatives. The included carrying case protects the delicate laser components during transport and storage.

Key Features

• Class IIIA red laser provides clear visibility up to 100 yards in daylight conditions
• Precision-machined brass construction matches exact .223 Rem/5.56 NATO chamber dimensions
• Integrated battery pack eliminates need for separate power source
• Protective carrying case included for secure transport and storage
• Compatible with all rifles chambered in .223 Remington and 5.56x45mm NATO
• Quick activation design allows rapid setup and alignment

The SM39001 proves invaluable for competitive shooters who need quick scope adjustments between stages, hunters sighting in rifles at remote locations, and tactical professionals performing equipment checks. The bright red laser remains visible in various lighting conditions, while the brass construction maintains consistent positioning shot after shot. Range time becomes more efficient as initial adjustments bring the rifle close to zero before live fire confirmation.
