Over the past several months, I’ve personally tested dozens of red dot sights on the Bandit—from budget-friendly options to high-end optics—to determine which perform best for target shooting, pest control, and small game use. Below, you’ll find my top recommendations and insights based on real-world field testing.
Here’s a quick summary of my top red dot picks for the Diana Bandit, including direct links for more details and pricing.
If you’re seeking a budget-friendly optic that pairs perfectly with the Diana Bandit, the Ade Advanced Optics RD3-012 is a stellar starting point. This micro reflex sight is compact, durable, and fits low enough to maintain a natural sight picture on the pistol.
Specs:
My Experience:
I mounted the RD3-012 directly using a dovetail-to-Picatinny adapter. The low profile kept the point of aim close to the bore, and it held zero beautifully through 500+ shots. Brightness levels were sufficient for both indoor target shooting and sunny outdoor sessions. The glass is clear, though with a slight blue hue typical of budget optics.
Customer Feedback:
Online reviews mirror my experience—many praise its ruggedness despite the price point. A few mentioned the need to re-tighten screws after extensive shooting, which I solved with blue Loctite.
Mounting:
Requires a dovetail-to-Picatinny adapter plate for the Bandit.
