It is a rifle built from a demilled parts kit. The receiver will most likely be US made unless the builder stole a receiver from a semi auto complete import rifle, which is highly unlikely. The barrel may be an original Romanian barrel or US made. If there are what look like random stampings/proof marks on the barrel under the handguards, it's original. Pics of that and receiver markings will help us tell you more.
I would see if it has full auto features:
-sear trip on the lower right rear side of the bolt carrier
-sear trip shelf on the bottom of the hammer that the sear catches. Semi auto only it may be smooth on the bottom.
-wide safety/selector which engages both disconnector and right side trigger leg (at different positions).
-long tail on the rear of the disconnector. The safety/selector engages the tail, holding the disconnector back from engaging the lip on the hammer for full auto, a semi auto only disco will be ground short, not touching the safety.
Hammer retarder/rate reducer installed? On Romy full auto guns, and others, they installed the rate reducer to reduce the full auto fire rate from about 900 rds per minute(?) to about 600 (?) making it more controllable(?)
Modern commercial rifles made for the ban era US market will have these full auto features ground off or not installed. As well as the evil bayonet lugs ground off, no muzzle threaded, no muzzle device, cleaning rod loop ground off, etc...
The generic term / label for what you have would more accurately be AKM
The Romanians never manufactured a “AK47” or a similar version of the original Russian milled AKs like several other countries did.
