High end mechanical... Almost an oxymoron. Best bet I would say is the tippmann x7. Not necessarily high end but it's the higher end of mechanical. The tippmann crossover or x7 phenom might work with CO2 and operate as mechanical. Need to check the CO2 part though cuz I'm not %100, maybe about %88. Otherwise, if you want that performance with CO2, you might have to look into marker that came out before HPA became king, something like a 2002ish impulse or something. Although they still don't run great on CO2 either, they just can.
Most guns that run on CO2 and HPA stay towards the lower end because usually its beginners who have not yet invested in HPA. You'll be limited to mostly spider, tippmann, and BT guns with CO2.
