What I don't like about my SAKO Finnlight 75 is that prior to every deer season it takes me, at best, two shots to sight-in and I am done. Where's the fun in that?
Seriously, for the price you stole the gun. I wonder why so cheap?
SAKO or Leupold rings work good. I use a Leupold Vari-x-II silver lightweight scope in 3X9. (Looks good on the gun and keeps the lightness theme going)
One thing, after many years, I still have yet to do and recommend it for you is to buy another magazine. My in 6.5x55 will cost about $125. But I think it is an important back-up.
One last thing.....way back they had trouble with Finnlight barrels coming apart (exploding) so check the serial number on yours and make sure it is not on the effected list. That MIGHT account for its lower price. (I doubt it)....
