The Century International Arms C93 is essentially an H&K G33E parts kit with American receiver, barrel and a few other parts thrown in. Actually, it is a great little shooter. I am looking for more sources for magazines. The only ones offered by century are the 40 round aluminum ones. I know that H&K also made 20 round steel mags, and are currently making 25 or 30 round mags for LEO use. Does anyone know where I can find G33E surplus mags at a reasonable price? Century ( and J&G sales) charge $49.95 EACH for the .223 cal 40 round mags.
