Will this work in a Ruger 10/22 rifle?

Yes , I used it on my ruger 10/22 takedown and it works great.

What is the range of this laser? I'm going to be using it to shoot an electronic target that will beep when I hit it.

that wont work with this. I have no idea about the range, but the black battery box that hangs off to the side has a cable attached to the part that inserts into the chamber. you push it in with you finger while the rifle is held in position on a bench. if you try and hold it free hand, the cable is going to wobble, and the will make the laser wobble, and...well I think you see where I'm going. I guess you could try and rig something up, but I don't think there would be any consistent accuracy. this is a laser boresighter, for setting up a scope. it is not trigger activated. think of using a sword in an archery contest.

will this work in my glock 23? 9mm

No it will not, a glock 23 is a 40 s&w bullet, unless you converted it to a 9mm with a barrel swap and this product still wont work in a 9mm

Will this work for a .22 magnum?

The laser bore sight itself is shaped just like a .22LR and extracts when you cycle the bolt via the extractor. So if the only length/dimension difference is forward of battery....I would think it should. Hope that helps. Don't have any .22 magnums.
