Rishi's Assault Cannon MK-1

All Blaster Cannons with the Dorne sound type have the same sound, including the Rishi's Assault Cannon MK-1. This isn't the official name, and this Blaster Cannon sound type may be labelled something like weaponrangedcannonnormal04 in the background of the game.

I do not have a video of the Rishi's Assault Cannon MK-1, but you can watch a video of the Z-403 Sentry Projector weapon to hear the Dorne sound type, which is the same as the Rishi's Assault Cannon MK-1.

These weapons can be purchased directly from a vendor called the Cosmetic Weapon and Weapons vendor (Z9-V86 droid) in the Supplies section of the Fleet. The versions from this vendor are Bind to Legacy. These weapons do not change between factions and you can buy all the sets on either side. Each piece costs 3,500 Tech fragments plus 500,000 credits, so a full set is quite expensive, but is accessible even to free-to-play players if they save up and buy the set piece-by-piece.
