MCREHOTZ Professional Bore Sight Laser Kit： Green BoreSighter with 50 Adapters Perfect for Sighting - Trustworthy Bore Sighter kit for All Guns - .17 Cal to 12 GA Rifle & Pistol

This was a perfect gift for my brother-in-law. It's an excellent kit with multiple adapters, the laser sight works very well and is easy to use. The green/red laser is bright and accurate, and the adapters fit a wide range of calibers. Solid build quality.

Great Quality and Very Convenient This bore sight kit is well made and comes in a sturdy case with everything neatly organized. It’s easy to use, accurate, and saves a lot of time. The variety of pieces included makes it very versatile. Excellent value for the price and works exactly as expected.

If you’ve ever tried to sight in the old-fashioned way — aka “shoot, adjust, question your life choices, repeat” — this MCREHOTZ bore sighting kit feels like discovering fire. I went with the green laser (because green just feels more tactical and slightly cooler), and it’s bright enough to see clearly even in decent daylight. Drop it in the barrel with the correct adapter, and boom — instant reference point. No more wasting half a box of ammo just trying to get on paper. The 50 adapters are the real MVP here. From .17 cal up to 12GA, this kit is basically the Swiss Army knife of bore sighting. Everything is neatly organized, easy to swap, and fits snug without feeling sketchy. No wobble, no guesswork. Build quality feels solid and professional, not like one of those “hope this works” gadgets. It saved me time, ammo, and frustration at the range. I was dialed in way faster than usual, which means more shooting and less fiddling with adjustments. If you own multiple calibers and want a simple, reliable way to get zeroed efficiently, this kit is an easy yes. Five stars. My ammo budget and my patience both approve. 🎯

I was very impressed with the way this tool was laid out In the case with all the ferals laid out perfectly. The tool itself is well built and very bright green laser but there is one issue. I purchased this item to sight in my 17 HMR rifle and the tool even with no feral would not fit down the muzzle! It seems when they painted the aluminum shaft on the tool The paint was too thick. Luckily I had a Dremel and a sanding wheel and after very carefully sanding off the paint it barely fit down the muzzle without hurting the accuracy. The tool does work very well in sighting in the firearm and is consistent when removed and put back in. If you don't have a 17 HMR firearm I wouldn't worry about it, but those who do be warned you will need to do a little bit of modification work.

It works really well. Only thing I don't like is it gives you like a micrometer reading size of the barrel not like .45 cal or 9 mm and if you don't know what that is you just have to go through and find which one fits the barrel but no big deal just a little harder if you don't know everything about guns lol. But it worked really good I definitely recommend it it's well made and bright laser.

I got this to avoid wasting ammo while sighting in, and it definitely helps. It comes with multiple adapters, so it works with different calibers, which is very convenient. The laser is easy to see and helped me get a quick alignment before going to the range. I’m not an expert, but it was very easy to use. Just make sure the adapter is secured properly. Overall, a great tool to save time and ammo.

I recently purchased the Professional Laser Bore Sighting Kit, and I couldn't be more impressed. As an avid shooter and gun enthusiast, I’ve tried a variety of bore sighters over the years, but this kit truly stands out. Here's why: Precision and Versatility The green laser is exceptionally bright, even in daylight conditions, making it incredibly easy to align your sights or scope with pinpoint accuracy. It comes with 50 adapters, which means you can use it for virtually any caliber, from .17 to 12GA. I’ve used it on my rifles, pistols, and even a shotgun, and the results were consistent every time. Whether you’re sighting in a hunting rifle or a home defense pistol, this kit has you covered. Ease of Use Setting up the bore sighter is a breeze. The adapters fit snugly into the barrel without any wobble, ensuring a true alignment. The instructions are clear, and the entire process takes just a few minutes. No more wasting time or ammo trying to zero in at the range! Durability and Build Quality The build quality is top-notch. The aluminum construction feels solid and durable, which gives me confidence that it will last for years. The laser module itself is well-sealed, so I’m not worried about dirt or moisture affecting its performance. Cost-Effective This kit has already saved me a significant amount of money on ammunition. I no longer have to shoot dozens of rounds just to get my scope zeroed. It paid for itself after just a couple of uses. Additional Features I also appreciate the compact carrying case that keeps everything organized. It’s perfect for taking to the range or storing at home without losing any small parts. Conclusion If you’re serious about improving your shooting accuracy and saving time and money, this bore sighting kit is a game-changer. The combination of precision, versatility, and quality makes it an essential tool for any firearm owner. I can’t recommend it enough! Do yourself a favor and add this to your toolkit—you won’t regret it.

Product is very easy to use and has a great selection of adapters for multiple different calibers. As well as a very bright green laser which had no problem seeing at 100+ yards. However I feel like the manufacturer could have used a more durable material for the bore adapters. I would also like to point out that anyone purchasing this product needs to understand that the more you use the adapter the more of an offset it will put of the laser down range. That being said the first time I used it was on a rifle that had already been sighted in at 100 yards. In the pre sighted rifle at 100 yards the laser was off center by 6in left and 8 1/2in high. After seeing the laser off center I decided not to make an adjustment to the scope but to remove the laser from the bore of the rifle detached the adapter from the laser then reattach it and placed back into the bore as the instructions indicated. The second time after setting the laser into the same bore of the same pre-sighted rifle the laser was then off center by 3in low and 10in right at 100 yards. My conclusion is that if your wanting to use the laser on a new rifle, shotgun or pistol I think it would be great to for a rough sighting. But you would still have to make final adjustments using ammunition. Overall build- solid laser Visibility at distance- very good hard after 140+ yards daylight Adapter selection- great but poor quality material Laser consistency for accuracy- poor Weapon variety- can be used in anything with a barrel more then 4in nothing shorter. Can also be used on a rifle that has a muzzle break You will still have to use some ammo but it’s great for a first time set up ranging at 50-100 yards.
