Anyone used the US Optics Boresighter? They don't push it, but they do recommend a magnetic type sighter like theirs for bore sighting.

I noticed that Midway is selling them now, and was wondering whether anyone had any experience with them.

Being USO, I am sure it is good kit. That being said, I have never needed any type of boresighter other that my eyeball.

Just steady the gun on a bench, pull the bolt and look down the tube. Adjust your scope until the bore and the reticle are alined and shoot.

This of coarse works best with bolt guns, but can also be used on gas guns.

USO actually sells the one they use. I have one and it is made by a company called Hakko I think. Works well. For getting on paper it works about as well as the eyeball method. They are handy when you need to remove and replace your scope at home or some other place that wouldn't allow you to immediatly fire it to confirm your zero.

I use the Leupold Zero Point boresighter and LOVE it! It's definately cheaper, smaller (fits into even the smallest range bag), and works great! It's also a magnetic boresight, but it's extremely small profile and ease of use make it winner.

I'm always swapping scopes between my rifles and this little unit makes zeroing a breeze. While I love my USO SN-3 and I'm sure their boresighter is a good one, the Leupold Zero Point gives a bigger bang for the buck in my opinion,... just my $0.02

But that wouldn't afford me the excuse to spend more money on gun stuff...

Kidding... I'm working on my first bolt gun build and my USO is coming this week. I am gonna give your method a try before I spend more money I shouldn't spend on gun stuff.

Re: US Optics Boresighter

To be fair, although I use the eyeball method, I have run into situations that a tool would be handy. There are some guns that the cheek peice or comb is in the way of the bore and are either not removable or I don't want to.

I can see the advantage of having a bore sighter in these situations.

Lots of people do that but what if you are swaping scopes between rifles, or need to take the scope off the rifle to work on one or the other. The boresighter allows you to go right back to the zero that you had previously established the last time that scope was on the gun. That can be done in your garage, instead of having to look down the bore at the range or in the field.

I make a notation in my data books exactly where on the grid the crosshair needs to be for my 100 yard zero's

JRose: I use USO rings on my .260 which are windage adjustable. Optically centering the reticle and then steering the scope to center (on paper) using the rings will maximize windage both left and right, AND maximize elevation.

Edited: i haven't come across a rifle yet where i could set an optically centered scope into a set of good quality rings on a one piece base(my Surgeon included), and have correct windage at 100 yards. It is always off to one side or the other. I think everybody knows this but unless you count windage in either direction after zeroing, there isn't a number in your head. The bore sighter is graphic in that sense.

This gives you some idea what he's talking about:

With the right mounts and rings, you can center your scope so that you can use all of it's adjustments starting from zero, and also take out any misalignment your mounting points might have with the barrel, rings, etc.

Drop dfar a pm. If he doesn't have one he'll get one quick AND at a good price.

Dfar or DAFAR? I thought DAFAR was the guy that carried USO stuff.

Re: US Optics Boresighter

I have a USO boresighter - from USO, excellent kit. Multiple uses, bore sighting, checking 'empty' clicks, box testing a scope,checking scope poi shift through magnification range.

There are other ways of acieving the same but that involves range time (box testing / tracking) - think of it as a piece of equipment that you can use before putting rounds down the bore. A boresighter should give you a good indication your scope is working correctly - range time confirms this.

I think I'll just order the Leupold myself, good idea it looks like it does the same job.
