Archived [ARCHIVED THREAD] - ? on Upper Markings
Posted: 7/1/2003 4:42:27 AM EDT
I bought a preban Essential Arms rifle that has a FNMI barrelled A1 upper on it. The upper is marked PM underneath the rear sight. I looked up biggerhammers index but I didn't find any of the manufacturers codes that matched. I was  wondering if any of the members here would know what that stood for.
