Your Opinion on Laser Bore Sights?

With laser bore sighters, you have to understand that they are not meant to get you absolutely zeroed. They are primarily meant for getting your scope on paper at short distances (50-100 yards). While other options, such as mechanical bore sighters, and "looking down" your chamber will work, laser sighters are much faster and can be used for almost any sort of gun or optic system.

With a laser, you can probably get within 5-6 inches of a true zero, depending on the circumstances. I've actually even seen one get within 1moa of a true zero, but that was likely just good luck.

There is no special trick. Like I said, its just for getting your scope to print on paper so you can do a real zero on it. that way you are not wasting any rounds.

I would not recommend it for "checking" an already zeroed in gun, it should be used for when mounting a brand new optic.

Laser Bore Sights

I have one of the inexpensive universal boresighters that go into the end of your barrel. I fiddle around with scopes enough where it's been a very handy little tool. Like most others have said, they get you in the ballpark, and you'll usually be on paper at moderate distances, and then you fine tune from there. As many others have also said light doesn't drop with gravity the way a bullet will,. As a result I didn't have much luck in the beginning boresighting my muzzleloader. However on just about any other rifle my shots have been on paper.

One trick I've found with this style, is once you have the scope close, rotate the boresighter around, as it's not perfectly aligned with the barrel, once it makes a little circle around your crosshairs as you rotate, you'll be fairly close. It also works best to do this at dawn or dusk, as the red laser does not show up well in the sunlight. If you have an old barn out back you can sometimes see the laser in daylight from a distance if pointed inside. But this may also raise a few safety concerns.

For simply checking the zero like you say, these may be a waste of money for you. Remember boresighting is simply designed to get you on paper at a short to moderate distance. It will not tell you if your zero is off a little. For a scope or any sight to be off this much, it would have required quite a big bump or drop, or else little gremlins who readjust them while you're not looking. However if you ever replace sights or scope on anything, they are an incredibly handy tool and often save some ammo and headaches.

Best Laser Bore Sighter

If you can see through the bore, like on a bolt action rifle with the bolt removed, you don't need a bore sighter, just look through the barrel.

1. A bore sighter will get you on paper at 50 yds most times. Laser light travels in a straight path after leaving the barrel. Bullets begin dropping in a parabola as soon as they clear the barrel. If you line the bore up with the target, the bore may be pointing above the target before the bullet leaves the barrel when you shoot a rifle.

2. See 1.

3. No.

It might be possible to sight in a rifle and then see how far the POI is from the laser at a given distance.

I have one that's the cartridge type for my .300 win mag, and the "cartridge" if put into the chamber and the bolt closed. It's pretty cool turning my bolt into a laser gun!

As far as your questions:

1) Yes, they work well

2) They get you in "the ballpark". I've found it helpful as my scope (before I finally broke down and locktite'd it) had some screws that would easily get loose. Thus, I've used it several times and each time it got me within 5 inches at 100 yards.

3) The best thing to do is to have something to aim at that's far out there. In fact, one time I even used it at night when I was living on a decent size property. I just pointed it at an empty hangar that was a good 150 yards away and through the scope I saw the little red dot and centered the crosshairs on it. To be fair, the red dot was fairly large, but still fairly circular so putting the crosshairs in the middle was easy. I was cracking myself up that I was able to bore sight my rifle in darkness.

4) I have no idea, as I'm only familiar with the one I bought. I got mine at a gun show for $20-$30 bucks and it came with batteries. If I were to purchase again, I'd probably try to get my hands on a multi-calibre option as it's only useable in one of my rifles.

Lasers? Some new gimmick, I guess. Ever look at the construction lasers? they're accurate to 1/4 inch in 50 feet thats 3/4" in 50 yards and 1-1/2 inches at 100 yards.

My opinion? Tacticool option for those with too much money and too little experience.

If you don't need to get them perfectly sighted a laser bore sight is the tool you need. It isn't meant to be a final sighting in tool it is a modern version of the basic old bore sighting that every gunsmith and shooter did for years. All it does is get you close when you are adding a scope or new sights.

A laser bore sight will NOT do what you want it to do because it simply shoots a flat line out of the barrel. It doesn't take into account bullet rise or drop.

I love them and don`t know how I got along without them....just like my cell phone. You have to pick a "sweet spot" distance because the dot is hard to see longer than 60 yards. Also, gravity doesn`t affect light so the dot will be higher than the bullet path. At 50 yards it is easier to calculate a 300 yard hoped-for hit.

The LASER sight makes aligning scope rings much easier.(along with a spotter scope)

They will get you in the ball park at worst within 6" at 100 yards and then you still have to "shoot site" after that all brands ive tried are about the same as for a trick make sure it is snugg in the muzzel
