I had put a compact bushnell scope on mine, and it couldnt take the recoil i guess, no matter how well it was mounted, my point of impact would change, sometimes dramatically. I took it off my ruger and put it on my muzzleoader, and no problems since.
I got a skinner peep sight and put it on my 77/44, and have never looked back! It looks good,the rifle carries better, weighs less and it is quicker (for me) to find the target than with a scope. It does the job WELL at woods ranges. Shot my biggest buck yet with it this past fall at about 80 yards.
You may want to look into it, I think mine was about 65.00 with shipping. well worth the money as far as I am concerned.
