There's generally a huge fundamental difference between Cyberpunk and Shadowrun when it comes to Rigging. In Shadowrun you can literally drive a tank disguised as a delivery van downtown, and the cops generally won't bat and eye. Okay so that's an exaggeration, a bit. Drones and vehicular weapons are fairly common in Shadowrun, and any rigger just has to go to the black market and pay the required nuyen and they can get military grade weapons and drones.
Cyberpunk is honestly more subdued. They have drones and weapons and tanks, but the corps try and control them much better. It's kind of weird in 2077 that Militech is very concerned about getting back their Spider drone, but don't care about their Panzer getting swiped. Generally you swipe a bit of military grade hardware that's that powerful, no matter how outdated, Militech is going to find you and remove you, and just moving the delivery truck a few miles down the road isn't going to deter them.
It's basically because in Cyberpunk, they've rationalized the gun thing based on the second amendment in Night City. Basically anything you can own today, even with a license, you can own in Cyberpunk, so basically small arms and maybe some machine guns.
Anything more powerful is going to require you to have a license or be hunted by every corp as a threat.
Shadowrun it's all illegial basically, so the difference between a Ingram and a Panther in the eyes of the law is that it's all illegial.
