When I purchased my new 223 laser boresight, I noticed that it was not aligned from the factory correctly.
After giving this some thought, I decided to place it in my 1/2" dril press. After gently inserting it, I placed a target on the table under it. I gently turned the chuck by hand. Sure enough, as I turned the chuck the laser drew a circle on the target. I made adjustments until a steady dot was achived as the chuck was rotated. I now feel, that the laser is better aligned than before. Try it, you may see the difference. |

I bought one that cost over $150, so I feel like it's a quality unit. AND it's made in AZ, so that's cool too. But it was always about 2-3" off at 50 yards, worse yet the further the target was pushed back - not acceptable; I like to test optics on rifles I build and don't have the time/money to be spending on a bunch of ammo just to get on target before I test.
I didn't use a drill press, but that's a great idea! Instead, I used a rifle with a pretty standard bore height (1.5") that was zeored at 50 yards and aligned the laser to the crosshairs. It was tedious, but now I'm much closer (within an inch usually) to the center of the target, and close enough to pump out a few rounds for testing without really having to adjust much of anything. |
| You would think that at least with the expensive chinese made one they would do that centering process before they sell them.The entire idea is to get on paper.My buddy has one we tried to set a scope for my silhouette rifle with and was not even on a 4' square of cardboard at 50 yards beginning the process.Ended up using that Leupold magnetic thing that you just slap on the barrel tip and roughly put the crosshairs on the things grid and click to it and do not see how it can work but does every time for me no farther than 4 inches from target center first shot.Centering is a great idea but on like the Wally cheapos are they made so you can make those adjustments at all? |
| Did you get the kind you insert in the muzzle, or the kind shaped like a cartridge? The problem I've had with a number of laser boresights that you insert in the muzzle is that it's hard to keep their pilots centered in the bore. If those pilots were covered with some sort of nylon sheath that was the right size for the bore, I think they'd be tons better. But I never thought about aligning the laser in the device... Either way, this would be a good thing. |

The one I have is a Site-Lite. The body is tapered, which should - in theory - keep it concentric to the bore. Instead of an arbor, it uses o-rings to achieve the correct bore size. They usually fit tight, so I have no reason to doubt that it isn't working as designed. It's just the laser in the body of the unit wasn't perfect, so I had to fix that.
