Sitelite SL-150 Ultra Mag Boresighter Review

First Thoughts on the Sitelite SL-150 Ultra Mag Boresighter

The Sitelite SL-150 Ultra Mag Boresighter promises a quick and easy way to get your firearms roughly zeroed, saving time and ammunition at the range. Made by Sitelite, it boasts universal compatibility from .22 caliber rifles and handguns to 12-gauge shotguns and muzzleloaders. This product immediately caught my eye because of my experiences trying to sight in new scopes on various rifles and pistols.

I’ve spent countless hours, and wasted plenty of ammunition, trying to get on paper at 100 yards. The promise of a tool that drastically reduces this initial setup time was incredibly appealing. Unboxing the Sitelite SL-150 Ultra Mag Boresighter, the first thing I noticed was its compact size and the variety of adapters included. The unit felt solid, the magnets seemed very strong, and the overall impression was one of thoughtful design.

I’ve used other boresighting methods, including traditional mechanical boresighters and cheaper laser options. The mechanical boresighters are often cumbersome and require specific arbors for each caliber. Cheaper laser boresighters often lack the magnetic strength for reliable centering and repeatable results. The Sitelite SL-150 Ultra Mag Boresighter seemed to offer a better balance of versatility, precision, and ease of use.

My initial excitement was tempered with cautious optimism. I’ve seen claims of “instant zero” before, and they rarely live up to the hype. Still, the design and features of the Sitelite SL-150 Ultra Mag Boresighter suggested it had the potential to be a significant time-saver.

Real-World Testing: Putting Sitelite SL-150 Ultra Mag Boresighter to the Test

First Use Experience

My first test was at an outdoor shooting range with a newly mounted scope on my .308 bolt-action rifle. The range was fairly typical, with covered shooting benches and target distances out to 300 yards. The weather was clear, but there was a slight crosswind.

Using the appropriate adapter, I inserted the Sitelite SL-150 Ultra Mag Boresighter into the muzzle. The magnetic connection was indeed very strong, holding the unit securely in place. Projecting the laser onto a target placed at approximately 25 feet, as recommended by Sitelite, was straightforward. Adjusting the scope to align with the laser dot felt intuitive.

After making the adjustments, I moved the target to 100 yards. My first shot landed about 8 inches low and 4 inches to the left. This was significantly closer to the bullseye than I would have expected without any boresighting at all. A few minor adjustments later, I was grouping within an inch of the center.

Extended Use & Reliability

Over the following months, I used the Sitelite SL-150 Ultra Mag Boresighter on various firearms, including a 9mm handgun, a .223 AR-15, and a 12-gauge shotgun. The included adapters worked perfectly for each. The unit consistently held its position, thanks to the strong magnets.

After numerous uses, the Sitelite SL-150 Ultra Mag Boresighter showed no signs of wear or damage. The aluminum body seemed durable, and the adapters held up well to repeated insertion and removal. Cleaning was easy; a simple wipe with a cloth was usually sufficient. Compared to my previous experiences using a traditional mechanical boresighter, the Sitelite SL-150 Ultra Mag Boresighter proved to be much faster and more convenient.
