Laserlyte Bore Sighter
Laserlyte Laser Bore SighterQuickly opening the box with my trusty Swiss army knife, and spilling plastic peanuts all over in the excitement, I removed a new red dot sight and a new Laserlyte laser bore sighter from the box. More about the sight in a later post.
The laser bore sighter is an ingenious combination of a laser pointer and a valve seat grinding pilot from an automotive machine shop. The end closest to the light source is tapered to fit into the muzzle, and the "pointy end" has a plastic expanding piece that can be adjusted to accurately fit into the bore. There are four different ends to allow the bore sighter to be used on anything from a .22 up to a .50 caliber barrel.
The Laserlyte also comes with a light-reflective target so you can see the red spot in bright daylight, and a handy little nylon/velcro carrying case to keep all the pices together.
Once you have inserted the bore sighter into the barrel, you rotate a cylindrical switch to turn the laser light on. Adjusting the sight is easy. Point the red light from the boresighter at a wall at the distance you want to sight in for, and adjust your sights to be on the red dot. That should at least get you close enough to do the final sighting in at the range.
Keep in mind that the bullet's path is not a straight line, as is the light from the bore sighter. At closer distances this isn't an issue, but as you move back it will be.
It makes a good learning device for demonstrating the effect of the sight being not on the centerline of the barrel, as you can adjust your sight for ten yards, for example, and then point it at something twenty yards away, and see exactly how much difference it makes. It can also be handy to carry along, as it gives you a quick way to make sure your sight hasn't moved on you since you last sighted it in.
Natchez has these on sale right now for $29.95, and that's quite a bargain, considering I've seen them advertised for over fifty bucks.
I think this is going to turn out to be a handy gizmo to carry in your range box. If you give them a call at Natchez and order one, tell them Mr. Completely sent you. They'll have no idea what you are talking about, but what the heck!
At the very least, you should get your hands on one of their shooting supplies catalog. I'd put it on the "Must Have" list of catalogs, along side of Brownell's and Midway.

Tip - a copy of the Natchez catalog is bundled with this month's issue of "Guns and Ammo" magazine. I had almost as much fun reading the catalog as I did the magazine!
One thing to be aware of when using a laser bore sighting system is that if you are sighting in a scope that is mounted well above the bore of the rifle (as in "see-through" Kwik-Sites, or when a large-diameter objective scope is used), the point of impact is still going to be significantly different from the straight-line out of the bore.
These things are also almost impossible to see in bright daylight. If you have access to an indoor range, you can use the laser at 25 yards to get a rough zero, and it will still be a (relatively) close zero at 100 yards. As you've noted in a previous post, there are two places where the trajectory will cross the line-of-sight of your sighting system. With many calibers, these occur at roughly 25 and 100 yards, handy distances.
With bolt-action rifles, I've actually had better success simply pulling the bolt and sighting through the barrel ("bore-sighting") than trying the laser sighting systems outdoors. Once you're on paper at 100 yards, adjusting the scope is a simple matter of counting the clicks up/down and over to put it at zero.
You're right, the lasers are hard to see in bright daylight, but I forgot to mention that the Laserlyte includes a special target that makes the dot visible even in bright daylight. It looks like it's made out of the same stuff they use on road signs and reflective strips so they show up well in your headlights.
