Laser boresight round for the Grendel?

[LR1955]

Just run the 7.62 laser through a sizing die... Ok, I'm kidding. I know there are lasers that are not meant to be inserted into the bore, but rather plugged into the end of the barrel. Like such:

I have one and they aren't worth the money. It is easier and more precise to boresight using the eye. They work like the Army laser bore sight devices for small arms. You have to put the carbine into a very secure rest, insert the laser using the right size spud, and once in and turned on you have to adjust the beam to the center of the target via four very small set screws arrayed around the end of the laser. Then you turn the device 1/4 turn and adjust again. And so on until you can rotate the laser without the beam moving on the target. It takes about a half hour if you have really locked the carbine into a vice that will not move when you rotate the laser.

The plus side to that particular model is that mine came with a reflective target so even in moderate sun, you could get a bounce to about 25 meters. The downside was that the beam is pretty big at that distance. And since guys use the 68 sight, it is pretty much useless.
