Put a quality receiver sight like Williams or Skinner and learn to use it. You will be very well served within the range of this rifle.
These rifles work well with peep sights. Far less bulky and lighter than a scope. I have a Williams receiver sight and fiber-optic front sight on my Guide Gun. Works great even with my old eyes.
Same here-and my seventy year old eyes have always needed a lot of help in terms of optical correction. I'm currently on the edge of having cataracts removed so, hopefully, I'll see better as I get older.
