I truly love my Holosun 503GU Circle Dot but the cost for it and similar sights approaches $300. In contrast, the Bushnell TRS-25 is a great optic at a price of around $70 and you can get a Romeo 5 for just over $100. Unfortunately, neither of the latter has the circle dot reticle I prefer.
When you move into scopes, the sky is the limit when it comes to cost. But there are less expensive alternatives if one can accept some compromises. For example, I recently purchased a Feyachi Falcon 1-4x24 illuminated scope at a cost of $90. While a bit on the heavy side, the glass is crisp, the eye box and relief are forgiving and it has my preferred circle dot reticle.
Please share your suggestions for other sights and optics that will not break the bank. Here is a link to the scope referenced above.
