My .02, I have something very similar, a PAC built STG. Mine has an unthreaded bbl tho.
It shoots very well as is, but I had an idea to ship it off to some well known FAL guy in AZ. That was a few years back, it would have been 1200 for fitting my old STG bbl (came with the gun), refinishing and replace any worn springs, safety stop and trigger job.
Really not that much $, but I didn’t do it. I just don’t shoot it as much as my 308 ARs. In fact, I picked up an SFAR 20” recently and it looks like the FAL got pushed further back in the safe.
Probably ought to sell it. Only paid 550 with a box of parts and the original bbl.
