Looks like someone did a rather poor job of refinishing the forend, too.
Other than that, it appears to be a nice looking rifle.
On the ones I’ve seen, the manufacturer’s markings have been on the left side of what (IIRC) is called the “buttstock socket”, which is the big band of steel at the rear end of the receiver which the rear of the triggerguard is attached to.
It almost appears there are some really fine markings yours, but maybe not.
Does the upper receiver have a “POF” marking on it? If so, that probably stands for “Pakistan Ordnance Factory” and likely means they rebuilt it. OTOH, if it was rebuilt there, I’d think it would be covered with black paint.
Other parts like the barrel bands, front sight protector, and such may have codes indicating where the parts were made. Also look at the top of the barrel underneath the handguard for marks.
However, if it was ever rebuilt (as is likely considering the scrubbed buttsocket) you could have a mix of parts.
