No it isn't. Hard Light is. Thunderlord looks nothing like Omolon. Basically all Exotics are "experimental and barely understood". I realize that FWC's weapons are going to be made by Omolon, but not yet. Thunderlord is unique and wasn't made by a manufacturer.

Red Death was made by a rogue Guardian. Universal Remote was made by a Gunsmith as a one of a kind piece. Hard Light is a prototype weapon. Suros Regime, Dragon's Breath, Vex Mythoclast, Plan C, Patience and Time, Ice Breaker, Queenbreaker's Bow, and arguably MIDA and Dreg's Promise are the only Exotics that, canonically, have more than just one iteration of the technology.
