I'm using a 4x Simmons scope ($35) on my 10/22, I can't remember which rings but I'm using an EGW 20 MOA base.
The scope was meant as a temporary rig so make sure I had the right height rings... and you know... the scope works out really well! I don't know that it'd hold zero on a .308, but for .22LR it's adequate!
I zeroed for 100 yards, and fortuitously, the 200 yard zero (using Rem Golden Bullet) is almost exactly where the crosshair meets the post of the plex reticle. Point of impact is off like an inch, maybe two inches at 200. So hitting targets at 100 and 200 yards only requires I put the target in a different part of the scope. It's fast and accurate.
