​What Is a Best Laser Bore Sight?

The laser bore sight projects a dot onto a target far away, allowing you to align your sights with the level of that dot and the bore of the gun rather than the sight itself. Though they may take some getting used to, once you get the hang of using it your shooting technique will be improved forever. The most effective and modern way to bore sight a gun is a laser, which is ultra accurate and reliable.

Types of Laser Bore Sights

There are essentially three different types of laser bore sights, and which one you get depends on how versatile you want the laser to be and how accurate.​

  • Cartridge lasers – are said to be the most accurate out of many types of laser bore sights, but they are caliber specific. This means you will need to buy a new one for every gun you own, which many find frustrating and expensive.
  • Muzzle inserted lasers – are made to have the same measurements as each caliber. Some are adjustable, but for others, you will need a new one for each gun.
  • Magnetic laser bore sights – are the last option, and they are becoming very popular due to their versatility. They can fit any firearm you own, but you may forfeit some of the gun-specific accuracies for this feature.

Best Bore Sight: Features to Look For

  • Battery Life – Sighting a gun can take a long time, especially if you want to get it just right and ensure perfect accuracy when shooting. If the laser bore sight is going to run out of battery in less than a few hours, it’s simply not worth buying it. You need to be able to sight your gun without replacing the batteries every half hour and potentially ruining your alignment.
  • Durability – Cheap laser bore sights are, in general, not going to survive heavy use for too long. Buy one from a reputed brand, so that you know it will last you for many years instead of just a few.
  • Brightness – This is the key feature of a laser bore sight, as is daylight visibility. Without being able to see the laser easily from a distance, on a bright day, the sight will be a hassle to use and may not be accurate.
  • Caliber – If you go for a type of bore sight other than magnetic, you’ll need to make sure that it matches the caliber of your gun.
