a few years ago I bought one of these from one of the few importers into the country. The barrel was a sako. Yes, the front sight is adjustible too.
Anyway, I cleaned the goop out of the barrel, loosely cleaned the rest of it, i.e. wiped it down, and took it out on the desert with some other rifles.
When done shooting the other rifles, I thought I would give the finn a try. Using cheap russian ammo. I loaded a stripper clip, and was firing at one of those red one gallon folger plastic coffee cans at 100yards. Hit the sucker five out of five.
The finns did a great job with these rifles. It has the hex 1891 reciever which they all have.
I might add that I ain't that great a shot, and was firing sitting on the tail gate of my truck, off hand.
