Aimshot BSB17 Laser Boresighter External Battery 17 HMR Brass

The Aimshot BSB17 Laser Boresighter eliminates the guesswork from rifle zeroing with precision-engineered brass construction and external battery convenience. This caliber-specific boresighter delivers consistent laser alignment for 17 HMR rifles, reducing ammunition costs and range time while ensuring accurate initial sight setup.

What Makes This Different

Unlike universal boresighters that rely on magnetic attachments or arbor systems, the BSB17 features machined brass construction that matches exact 17 HMR chamber dimensions. The external battery box design prevents heat buildup during extended use and allows battery replacement without removing the boresighter from the chamber. This configuration maintains consistent laser output and extends operational life compared to internal battery models.

Key Features

• Precision-machined brass body matches 17 HMR chamber specifications exactly
• External battery box prevents overheating during extended alignment sessions
• Class IIIA laser provides visible dot at 100+ yards in most lighting conditions
• Durable brass construction resists corrosion and maintains dimensional stability
• User-replaceable battery system extends operational lifespan
• Compact design fits standard rifle cases and range bags
• Compatible with all 17 HMR chambered rifles and handguns

The BSB17 streamlines the zeroing process for precision shooters and hunters who demand accuracy from their 17 HMR rifles. Whether setting up a new scope, checking zero after transport, or switching between different loads, this boresighter provides reliable reference alignment. The external battery configuration maintains consistent laser intensity throughout extended setup sessions, while the brass construction ensures repeatable chamber fit across multiple uses.
