I too have a C&S Metall-Werkes drum. Limited experience has shown it to be very reliable. Man, a 72 round mag dump just seemed to take forever though:)

C&S and Vector drums work. I also haven't had any trouble with an old ban-era Beta mag. All options are $$$.
I bought a Beta C drum right after the ban was lifted. I need to get that thing out and run some ammo through it.
Come on Magpul, we are counting on you for a reliable 40 round mag for PCC.
