Move it to the top and zero it based on the offset and trajectory. What do you use for your primary optic?
I would play with a ballistic calculator.
You can enter negative sight height for your under the barrel laser and see what the trajectory looks like.
Remember that your bullet ALWAYS DROPS, right out of the muzzle.
For close ranges, there isn't going to be much difference from one AR round to another.
For example,
Try -2 inches, 62 grains, 2500 to 2900fps, and either a 25yd or 40yard zero for the laser.
Then use those values and see what a 7 or 10 yd zero does out to 50 yds.![]()

Scope on top (+2"), laser on bottom (-2") 25yd zero on both. View attachment 7219229
I have a green Laser on an SKS.
Daylight @ 25 yards and it works OK. I don't have to cheek down to use the open sights.
I guess for home defense hitting an inch or so low at a closer range probably isn't all that bad.
Zero the laser @ 7 yards and watch out for planes

... I use mine for a different purpose. I take young kids hunting. I have them line up crosshairs on the animal. I turn on laser and if/when correct I have them shoot. Saves me some tracking at times ...
