Buying Guide

For someone who is new to the hobby, you may find all those information provided above to be overwhelming. With this buying guide, you’d know which product to choose that will perfectly match with your needs.

Material

Because bore sights are mounted or attached to a firearm, it must be durable, strong, and offer a lot of flexibility. Look for a boresight that is made out of aluminum alloy, as it’s the best material to use when making bore sights. Why? Because the aluminum alloy is a lightweight yet durable material, which makes it a perfect candidate for bore sights. Bronze and brass are the runner ups as both can provide those two aspects, but the aluminum alloy is still miles better.

Type

Bore sights have two major types. Both have its advantages and disadvantages, but one thing that you should prioritize is their accuracy. There is a cartridge type, and there is an arbor type. The cartridge type bore is inserted into the barrel, while the arbor is just attached to the muzzle. And the more accurate one out of the two would be the arbor type.

Laser Specs

If you want a high-range, accurate, and powerful laser, go for a product that has a Class IIIA laser-equipped. It’s the most superior type of laser that is legally allowed and is available for commercial use. Another aspect that needs to be considered is the range, which entirely depends on your preference and the same goes for laser visibility during daylight.

Performance

There are a lot of manufacturers that make high-quality laser bores, and there will always be the question of, who makes a better boresight. One key aspect that you need to take a look at is the overall performance of the equipment. From installation, mounting, fitting, accuracy, range, laser strength, and more. Another thing to consider would be battery life – what’s the point of having all those features if you can’t even use it without the need to constantly change batteries.

Versatility

A laser bore sight must be compatible with a wide range of rifles, that way consumers will avoid buying another laser bore system just to fit their other type of gun. A boresight should be able different calibers of rifles, because as the fire rate varies, so too is the adjustment and calibration.

Fit

This is the second most important factor to consider other than the power and performance of a laser bore sight. If your bore sight wouldn’t fit or attach perfectly onto your firearm, calibrating would be impossible as it would just jiggle and wiggle. The better the laser bore fits, the more accurate your calibration becomes

Price

Now, before you even search the market for your next laser bore sight, it’s best to determine your budget. Having a determined budget would allow you to narrow the search even more, and you can now start to look for the best bore sight within your budget.

Why we need Bore Sights

Some think that sighting and zeroing in a rifle is a quick and easy process, if you’re lucky, that is. Usually, sighting a rifle is a tedious process that wastes a lot of resources and money in the form of wasting bullets, just to get a rifle zeroed in with its new optics. It can be very frustrating and annoying having to shoot a target thinking that it’s dead set and accurate, only to see that it didn’t even hit it.

Luckily, there’s now a thing called bore sighting, which gunsmiths, gun enthusiasts, and professionals all over the world have been wanting for a long time now. Bore sights allow you to perfectly align your rifle and your sights accurately. It makes sighting a lot easier and less tedious, which experienced and new shooters would appreciate.

So why do we need bore sights? The answer would be to save time and save yourself from the tedious process of sighting your rifle.

Bore Sighting vs Zeroing

If you’re a new shooter, it’s important to know and differentiate bore sighting from zeroing. That way, you save time and ammo, and it’ll help you become a better shooter.

Bore Sighting

Bore sighting is the process of adjusting and aligning your rifle or firearm barrel to your sights.

Zeroing

Zeroing is the process of adjusting your reticle or sights so that the point of impact is where you’re aiming at.

Final Words

If you’ve ever had the experience of sighting your rifle and failing over and over again, with this product, that problem would be a thing of the past. Get yourself a laser bore sight so you can spend more time shooting and less time sighting.
