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

Came quickly, fits good, laser works well, i found out that these lasers do not get your firearm accurate. You can use it an then go sight in the fire arm. The product works but if your using it expecting your firearm to be accurate it will not be.

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!

Worked perfectly but it doesn't come with a case to hold the batteries like others. I would deduct a star, but it was cheaper than the other6

Very well made. And works great.

Set your sights at home and enjoy your range time more

Works perfectly in My Palmetto State Armory Saber AR-10 chambered in .308. I have no issues with this going in or coming out of the chamber. When my bolt is closed their is no indication that it is moving inside the chamber. I can't weight to get this out to 25 yards and zero my scope with it. The only way to turn it off is to pull out the batteries. I will have to get these in 7.62X39 and 5.56 depending on how well it gets me sited in. At 12 bucks that's cheaper than 10 rounds of 308.

This really helped me set the leaser dot at 15 yards for the 9Mm firearm, zero in perfectly without a smith help, all you need is a small target and Allen rench

Good but die too soon
