10's are not ready, but the all new Mach 4, 5, 6, and 7 are here. I cant put any together right now, but have the schedule clearing up in the coming weeks.
The new Mach 4-7 has more improvements over the new Mach 1.6.
A fully carbon coated pintle is one of the MAJOR changes. It is also lighter by a good margin VS the older Mach 4-7. The pintle speed is faster than ***ANY*** injector out there now. This also virtually eliminates wear on the pintle tip. A major wear area on the 24VP nozzles of the past.
