9MM/ .243 .308/6.5MM/300BLK 7.62x35mm/.44mag/30-06/25-06/270 Cal Rem Gauge Bore Sight Red Dot Boresighter with Batteries

This bore sight works amazingly well. I used it to zero my red dot sight on a 9mm pistol, and it made the whole process fast and precise. The laser is bright and easy to see even in decent lighting, and having three sets of batteries included is a great bonus—no need to worry about it dying halfway through setup.It fits snug in the barrel and doesn’t wobble, so alignment stays consistent. For the price, the quality is impressive. If you’re looking to save time and ammo when zeroing in optics, this is a must-have in your range bag. Highly recommend!

POS. Garbage. All included batteries were DOA. It's only $10.00 but I expected it to work. Imported Chinese garbage. Thanks Jeff. If I could give a zero rating, I would. However amazon won't let me. Go figure.I was drunk. Device takes two batteries. Works fine. I apologize.

This little tool has made zeroing in my various firearms a breeze. The versatility is a big selling point for me since it supports multiple calibers.The red dot laser is bright and easy to see even in broad daylight, which is a huge plus. It's a real time-saver and takes the guesswork out of sighting. The included batteries were a nice touch, I was able to use it right out of the box.The build quality feels solid, and it's straightforward to use. Just insert it into the barrel, turn it on, and adjust your sights accordingly.Overall, the Tipfun Bore Sight is a valuable addition. It's accurate, easy to use, great quality and reasonably priced. Highly recommended.

It works but the things tiny and will probably be misplaced. It was easy to use and the visibility indoors was great.

Well I have to say this is a great tool. Unfortunately the first one was no good and the laser was way off. The replacement was spot on accurate. Don’t forget to use the red dots on the back cap so the batteries don’t burn out as there is no shut off point. You can just do what I do and take the batteries out and put everything back in the box it came in. Overall I think this is a super too and you don’t waste time and money on rounds. You can accurately site a rifle in with 3 shots 4 at most.

I purchased these as a gift for my son. He says that they work well to help get his guns sighted in. He was very pleased with them.

Works perfectly I’m impressed

This little red laser is very cool. But honestly its not what I was looking for. Its just a bore sight tracer. THERE IS NO ACTIVATION. once the battery is put in. Its on. I wanted it to activate once hit by the firing pin. But still a nice addition to sight in any red dot .Pros:Easy to useFits gun very wellNice build qualityIncludes 6 batteriesCons:Always onNOT FOR DRY FIRE PRACTICE
