IR laser zero on CD COR Rail

[danieljmaunder]

Hey ya'll

I have a DBAL D2 thats going to be mounted on a cloud defense cor rail in the recessed lower section. I'm pretty familiar with zeroing IR lasers using the constant offset method and targets from telluric, my question is with the lower rail changing the HOB of the laser, whats the best way to figure out how to zero properly so I have a constant offset with no divergance at distance?

TIA

Just stick your muzzle against a target, circle around the muzzle device, turn on your laser, mark its location on the target, and you’ve got a pretty good reference point of what your offset is.

Alternatively, there’s a pretty good argument that within realistic engagement distances with a laser, that a converging zero may be preferable if you’ve got the distance to do it.

That is what I do on a target. Then I go to the range, shoot at 25 yards and zero laser for the same offset. Then do the same at 50 yards. I do not see the benefit in doing a coverging zero.
