momo, I would never bubba a collectible war horse like a M39 Finn, nor would I condone or advise doing it. The M39 supply has dried up, and the prices will only go up. I have no problem with mounting a scout mount on one, but use a good mount like the S&K Instamount.
Beware anyone selling a "Finn 39 sniper", especially with a PU scope on it like mine, they never existed. The very few "true Finn snipers" were either fitted with a PE/PEM scope or Ajack scope(less than 700 made), or the ultra rare PH sniper with a Physica scope(less than 100 made, only two known in the US).
This was a VKT parts gun. I don't think there's more than 3 parts on that rifle that had met before I got it put together. The scope is off of a Finn anti tank gun, and graduated to 2000 meters. The stock was broken in half right behind the rear band, and the barreled action came stuffed in a bubba M38 stock. I'll have to find a before pic and post it just for the shock factor.
I have an all matching wartime Sako, that was never refurbed (tack driver too!), and "had" a minty wartime Sako refurb I sold to a very good friend. We always shoot together, so it's like I got paid to shoot my rifle and I don't have to clean it.
