I would talk with the guys/Owners @
The Gunstore( Bob)
American Shooter's (Ron/Froman)
Discount Firearms (Mike/Anna)
Center Mass (Leon the Owner doesn't allow OC from what I am told)
Machine Gun Kelly's (if they are still open)
There are probably other shops I'm just not familiar with them.
They can probably steer you in the right direction.
The person I used no longer practices in NV.
If Bob isn't available ask for Tony D @ the Gunstore.
You could always stop by a sub gun match @ Desert Sportsman's and ask those guys/gals who they used.
