SME Sight-Rite Laser Bore Sighter 300 Win / 338 Win Brass Boresighter
The SME Sight-Rite laser boresighter is a caliber-specific tool machined to chamber dimensions for 300 Win Mag and 338 Win Mag, letting you align a scope or iron sights quickly and accurately before your first shot. This caliber-specific unit is machined to exact tolerances so it seats directly into your chamber and projects a high-output laser dot right where your barrel is pointed. Three alkaline button cell batteries are included in the package.
Key Features
- Caliber-Specific Chamber Fit — Machined to match the exact dimensions of 300 Winchester Magnum and 338 Winchester Magnum chambers, so the boresighter sits true and eliminates the alignment errors that universal arbor-style adapters can introduce.
- Precision-Machined Brass Construction — The brass casing is crafted to tight tolerances, giving you a repeatable, centered laser projection every time you use it and ensuring the unit holds up to repeated chambering cycles without deforming.
- High-Output Red Laser — Projects a red laser dot visible at typical indoor zeroing distances and in low-light conditions, so you can align your optic or iron sights without expending ammunition during initial setup.
- Batteries Included — Three alkaline button cell batteries come with the unit, so there is no additional purchase required before your first use — take it to the range or use it at home right away.
- Factory-Set Laser Axis — The laser is aligned to the bore axis at the factory for the stated caliber, providing a consistent starting reference point without requiring field adjustment.
