in the shell

Interesting these look like they were cobbled togetherfrom contemporary weapons.

The CA-25 looks like someone made a mac-10 bullpup and the m-22 looks like a p-90 with parts from a famas and a chinese assault rifle (the names sorta escape me) Maybe a type-97.

There are three varations of the c25 and the fnp clone is the c26 also in 3 varations.Im currently making a mod and have listed so far

GONG very pecular one this.

As to the rifle i dunno, the majour refered to it as a 30 cal alv or something like that.

I think I found out what his rifle was when he raided Locus Solus. It's a Sig 550
