Muzzle velocity for the CAR78a carbine is about the same as for the QB79 in factory condition. Although the shorter barrel reduces muzzle velocity, I fit the carbine with our improved breech seal as standard and that brings the muzzle velocity back up. Accuracy is improved compared to a factory QB79 due to the standard muzzle brake on the carbine.
Currently the CAR78a is out of stock as we're awaiting parts, but I'm hoping that it will be available again soon (within a few weeks) following our next delivery of parts from the Shanghai factory.
