I have a Sig Sauer on my 300RUM and it is amazing in low light and clear love it best scope i have found. But they are a little pricey. You might want to check them out.I'll start off by admitting the most expensive glass I've had the opportunity to personally test is the Leupopd VX5 HD. Most of my deer rifles wear various versions of the VX3. Comparing these to others based solely on low light for their prices I've not seen any that outperform. However my experience is limited to a few makes and models. How do other brands and models compare to these solely on low light ability?
