After much research I decided on a Nikon Prostaff EFR 3-9 X 40. Then, just now, when I couldn't put my order through at Midway, I turned around and bought a totally different scope on Ebay because I needed one NOW! Anyway, it's a Swift with a 50mm objective and I need advice on how to mount it. A lot of folks seem to like the Burris PEPR and it makes sense to have the rings on one base. I'm also looking at the Stoner AR mount. Any advice? What about height? Old eyes here too. BTW, Swift makes some pretty decent glass, I've had a pair of their binoculars for years...which reminds me, I'd like to trade them for something smaller, but that's another post.
