There's a weird association for me between tinkerers, older players, and members of this forum. In my mind, if you mix and match parts that never should be mixed and matched or if you've been playing since the days of Uvex goggles, you MUST be on this forum. Them's the rules.
So it blew my mind when I was at the field and saw a guy who grafted an A-5's e-frame to an Automag and he told me he's never heard of MCB.
Blew my mind, I tell you.
Not wholly related, but your post had a "spirit of paintball" vibe that reminded me of all that.
King Kong rules.
