Sightmark SM39021 Red Laser Boresight .22 LR Brass w/ Battery & Case

The Sightmark SM39021 boresight eliminates guesswork when zeroing .22 LR rifles, saving ammunition and range time with precise laser alignment. This brass-constructed laser boresight chambers directly into .22 Long Rifle firearms for instant bore axis reference.

What Makes This Different

Unlike universal magnetic boresights that approximate alignment, the SM39021 chambers exactly like a live round for true bore centerline projection. The red laser provides clear visibility in most lighting conditions up to 100 yards. Brass construction ensures consistent chambering across different .22 LR rifles without binding or extraction issues.

Key Features

• Precision-machined brass case matches .22 LR chamber dimensions exactly
• Class IIIA red laser projects visible dot up to 100 yards
• Includes rechargeable battery pack for extended use sessions
• Protective carrying case prevents damage during transport and storage
• Compatible with all .22 Long Rifle chambered rifles and pistols
• Simple activation - chambers and activates like loading ammunition
• Durable brass construction resists corrosion and wear

Range sessions become more efficient as initial scope adjustments get rifles on paper immediately rather than searching for impact points. Competition shooters use boresighting to establish baseline zero before fine-tuning with live fire. The consistent brass construction chambers smoothly in match-grade chambers while extracting cleanly without residue. Weather-resistant design functions reliably in temperature extremes from -10°F to 120°F.
