I can't recall what nozzle the umps use. the ares is crap. Of the ump owners I've spoken to only 1 has held both the g&g and the CA. he said the CA felt nicer on the external plastic. I can't recall what cylinder head is used on either one, but I might have seen something about the 2 using different nozzle/cylinder head but that needs further research. The ump is a big gun, it's kind of deceiving and the mags are almost as cumbersome as p90 mags. I'd probably have one if I had money to spare.. cause I'm an hk whore like that. Both were v3 otherwise outside of the cylinder head and nozzle possibly being unique.
