Yeah, they book at 14oz and only go up with the ASR mount. The Omega is heavier than a full-Ti tubeless can like a TBAC, but also designed differently. Tubed, cobalt-6 blast baffle, bravo threads, rated down to 10.5" 5.56 for SBR use, full-auto vs 800* temp rated. More along the lines of the Dominus SR-mount models than a precision lightweight can like the Ultra series.
The Omega 300 and Ultra 7 were designed for different goal sets, calling one a turd over weight alone pretty much ignores every difference in design that went into both of them. The light weight all Ti-construction of the TBAC Ultra 7 would make it a turd if you tried to put one on an SBR and run the SOCOM firing schedule that TBAC used to rate the Dominus/ Dominus-K SR mounted designs.
