+1 for the Vortex! I have the same one! If you're looking to keep costs down for a 10/22, might wanna check with Midway USA. They have a Simmon's Whitetail Classic 6.25-20x50 Scope, with AO (Adjustable Objective...)
, for $109 with the Truplex Reticle, and $124 with the BDC Reticle.
Some folks scoff at Simmon's Scopes, but I've got 2, and they're great, IMHO, for a Rimfire Rifle. Here's a pic of one of mine, on my S&W M&P 15-22:
FYI, you'll need some High Rings or a Riser, to get that 50mm Objective off of the Barrel!
I have Nitrex, Vortex, Nikon, Millet, and Simmon's Scopes, and my Simmon's work just fine for a .22 Platform. FYI, my wife has been shooting her Marlin 795 for the last three years, with a Simmon's 3-9x40 Scope. It's never lost Zero, and hits that big Red Spot on the paper, every time we go to the Range.
Best of Luck!
