My favorite is the Vortex Viper 2-7x 35mm but unfortunately they were discontinued. I wish I would have bought two.
I'm interested in the Weaver 2-7x 32mm that Natchez has on sale for 119.99 right now as a scope for my son's Marlin 336 where I can get my better scope off of it.
7x is a lot for a 336. You might consider the Weaver V 1-3 with 4.13" eye relief and less obtrusive handling characteristics.
