When the Koreans first started to produce thier own ammunition, for the guns we sent/sold them, it was corrosive primed. One of the reasons alot of the BlueSky Carbines needed new barrels. Yep there's a fool falling off the truck every minute, but for everyone here if you want an M1 Garand go the CMP route, you'll get a quality gun, quality service, and wont have to worry about when its going to fall apart.
