This is a Yugoslavian M48 used by military police and police stations, which has been threaded at the muzzle for a Yugo M81 grenade launching attachment. The threads are 1:14 left hand. Very few of these were made since the police soon got M70 AK rifles with threading already present. There is also a "F" and fainter "A" above it on the buttstock. This modification seems to have been performed before the 1990's wars.
The rifle is in good condition and matches numbers. There was cosmoline in the threads which shows they were there before importation. Oddly, the safety on the bolt is completely missing.
This thread has one rifle imported into the USA, which has a deactivated/altered safety:
