Pablo,
the logistics are probably next to impossible...I only know about buying/selling locally, and it's not pretty.
I've shot a few yellow/black shoulder afternoons with it, and most of the guys in the club don't get through 5 rounds.
Doesn't like cast lead (microgroove style rifling), but lives OK on Brazilian jacketted.
Our range won't accept it anymore (Army with 50 cal is OK 'though).
Want to replace it with an M39 at some point
