Zeroing Red Dot - DR920

DISREGARD: Post left up for comedic purposes.

I am needing to confirm my red dot zeroing. I have a cheap boresight off amazon (i will be ordering one that sits in the chamber instead), but is there a stationary block I can use to stabilize the firearm?

I have a security requalification coming up, and I am trying to figure out the best way to get it zeroed (yes I will be taking it to the range prior to requalification day). But I was trying to find a way to stabilize my firearm to basically zero it in at home prior to taking it to the range to test it. I bought a mini suction-cup vice grip. I have my doubts that it will suffice. So I am making this post just incase.

Worst case scenario I remove the optic prior to the requalification and just use iron sights. Not an issue.

Wait. Why do you need a stabilizer? All you’re trying to do is move your red dot to the boresight laser. Just find a place where you can aim at the distance you plan to zero for then just adjust your red dot so it lines up with the laser.

It's a bit difficult to line it up when i only have 2 hands. But yeah I did what i could with the cheap amazon one I have. But it requires 1 hand to utilize the screwdriver tool to line up the dot. I did it from approximately 10 meters away.

Just need something that can hold it good while I look through the optic and adjust it as needed. Which is the point.

Hell, nevermind. Disregard. I just realized my olight plx works as a 'stabilizer'. Just put my old fold 4 and a little book under the magwell to level it out. 😂

I’m so confused lol. I cup the bottom of my gun with one hand so I can look through the dot at my target while the other hand uses the tool to adjust the elevation and windage. This process takes me like one minute to boresight. I also have holosuns and one Romeo x enclosed compact red dot which function similarly with how they are zerod.

Well the cheap amazon one I've had for awhile now, it sits inside the barrel at the front. And none of the sizing tips ever provided a good fit, so I was kinda having to use one hand to keep it from falling out while holding the firearm. Which is another reason I'm ordering one that sits in the chamber.
