The border patrol version no doubt has better E/O performance.
As for arming them they are basically the same the CIA uses for plinking terrorists so the hard points are already built in.
What I do not know is if the BP has its own pilots or uses USAF/USMC/or CAANG to fly them. But transferring control to Creech AFB, NV would be a simple move and you would have pilots already trained to go weapons free
