SME Sight-Right Laser 243/308 Winchester / 7mm-08 Remington Boresighter Review

The SME Sight-Right Laser 243/308 Winchester / 7mm-08 Remington Boresighter Made a Bold First Impression

The SME Sight-Right Laser 243/308 Winchester / 7mm-08 Remington Boresighter promises meticulous accuracy, and in a world where precision can make or break a hunt, that’s a claim that demands attention. Boresighting can be a tedious task, often involving multiple trips to the range and a significant amount of ammunition. I’ve always been on the lookout for a reliable, caliber-specific boresighter to streamline this process, and the Sight-Right piqued my interest with its brass construction and high-output laser.

My primary goal was to reduce the time and resources spent on initial sight-in, especially when swapping optics on my rifles. The package arrived in a simple, no-frills container, containing the boresighter itself and three button cell batteries. The brass casing immediately felt solid and well-machined, a welcome contrast to some of the cheaper plastic options I’ve encountered. This initial impression gave me a surge of optimism about its potential performance.

I’ve previously used universal boresighters with expanding arbors, and while convenient for multiple calibers, they often lacked the precise fit needed for truly accurate results. I considered a couple of magnetic barrel-mounted laser boresighters, but I questioned their consistency across different barrel profiles. The SME Sight-Right won me over with its caliber-specific design, promising a more exact alignment with the bore.

The first impression was surprisingly positive, especially considering the budget-friendly price of $15.49. The solid brass construction exuded quality, and the laser appeared bright and focused. I was eager to see if this little tool could live up to its promise and save me time and ammo at the range.

2. ## Real-World Testing: Putting SME Sight-Right Laser 243/308 Winchester / 7mm-08 Remington Boresighter to the Test
   ### First Use Experience

I first tested the SME Sight-Right at my local shooting range on a .308 Winchester bolt-action rifle. The range offered a controlled environment with distances out to 200 yards, perfect for validating the boresighter’s initial alignment. I mounted the boresighter into the chamber, ensuring it was fully seated.

The laser projected a clear red dot onto the 50-yard target, easily visible even in daylight conditions. After adjusting my scope to align with the laser, I fired a three-shot group. The group landed approximately 4 inches high and 2 inches to the right. A little off, but easily correctable and far better than a completely random shot placement on the target.

The ease of use was a major selling point. Inserting the boresighter was simple, and the clear laser projection eliminated any guesswork. One minor issue I encountered was the button cell batteries. They are small and fiddly to install, requiring a steady hand and a bit of patience.

Extended Use & Reliability

After several range sessions and optic swaps over a few months, the SME Sight-Right has consistently delivered similar results. It reliably gets me on paper at 50 yards, saving significant time and ammunition. The brass casing has held up well, showing no signs of wear or deformation.

The tool is easily cleaned with a dry cloth, and the batteries have surprisingly long life. I’ve only had to replace them once in months of use. Compared to my previous experiences with universal boresighters, the SME Sight-Right offers a significant improvement in accuracy and consistency. It’s a simple, reliable tool that does exactly what it promises.

Performance & Functionality

The SME Sight-Right Laser 243/308 Winchester / 7mm-08 Remington Boresighter excels at its primary function: getting you on paper quickly and efficiently. It eliminates the need for excessive shots and adjustments during initial sight-in. Its accuracy is commendable, consistently placing shots within a few inches of the bullseye at 50 yards after scope adjustments based on the laser’s projection.

The only real weakness lies in its limited caliber compatibility. If you own rifles chambered in other calibers, you’ll need to purchase additional boresighters. However, for those shooting .243, .308, or 7mm-08, it meets and exceeds expectations.

Design & Ergonomics

The brass casing feels solid and well-machined, inspiring confidence in its durability. Its size is perfect for easy storage in a range bag or toolbox. The design is straightforward and functional, with no unnecessary frills.

Durability & Maintenance

The brass construction suggests that the SME Sight-Right will last for years with proper care. The only maintenance required is occasional cleaning with a dry cloth and battery replacement.

Accessories and Customization Options

The SME Sight-Right is a standalone tool and doesn’t offer any customization options. It comes with the essential components: the boresighter and batteries. It’s compatible with any rifle chambered in .243, .308, or 7mm-08 with standard optics mounting systems.
