The Sightmark SM39021 Chamber Laser Boresight gets you on target quickly without wasting ammunition—simply drop the boresight into your .22 LR chamber like a standard cartridge, and the bright red laser will show exactly where your rifle is aiming. When done, it ejects like an empty casing, clearing your chamber and allowing you to proceed straight to live fire without the risks of forgetting a bore-mounted sight.
Emitting a bright 632–650nm red laser, this boresight is compact and lightweight, designed to fit .22 LR chambers. The Sightmark Laser Boresight provides a convenient and accurate method for sighting in rifles—it’s easy to sight in any scope without firing a single shot. Live fire is only needed to fine-tune the weapon to compensate for inconsistencies such as bullet drop due to distance.
Perfect for hunters, competitive shooters and law enforcement, this boresight includes a carrying case, batteries, and instructions. It features a compact and lightweight design that fits in any range bag, making it an essential tool for quick zeroing and sighting in on the field.
