I have a 8-32x56 with what I consider the same problem....the side focus is in my opinion extremely stiff, stiff to the point that at first you don't think its going to move. I've sent a email to sightron months ago and haven't recieved any response at all. I love the scope but hate the side focus tension....one thing is I dont have to worry about the adjustment moving unintentionally...lol.
Would be nice to know if this can be repaired under warranty.
