I have a very clean factory produced FMAP SLR Argentine (Rosario mfgr) fixed stock FAL.
A ~17.3" barrel and a Papa New Guinea (F1) muzzle device shows barrel shortened and RH threaded.
The lower and BCG #'s match. The upper has a X.... serial. no import stamp I can see? IIRC reading years ago, importer took guns apart to ship, and didn't rematch.
Anyone know history or value?
