Here's what I decided to do. I got a red dot sight for my birthday a few months ago. We all know what happened when I mounted it. It was to low. The red dot showed up in the middle of my front post. Before I spend $$$ on another red dot. Today I ordered a medium height riser to mount my current optical on. I'll see how it looks. If it is the correct height, I'll check it out further. If not I'm only out $12 for the riser. Then I'll order the Bushnell TRS-25 Hi Rise.
