I haven't tried to get any of the Helos scopes in to re-sell, but that's mostly because I had seven of the Ares 4.5-27x50 mil scopes in stock that I needed to sell. However, for the guys who're just getting their feet wet in more advanced shooting scenarios with their 22RFs, the Helos would definitely be more attractive at $570 than an Ares would be at $850.
I shoot 22RF PR matches with several guys who are realizing they need better scopes on their rifles to allow them to both see some of the smaller targets at extended range, and to have reliable tracking. Like me, they didn't feel the need for better scopes when they were just plinking at tin cans with their rifles, but as soon as they got into a more competitive scenario - with targets from 25yds out past 200yds - they realized how handicapped they were by their scopes' limitations.
I have an Ares on one of my own rifles - an older M70 pushfeed with a Krieger in 6x47, in a Manners T4A stock. That scope has been very good, both in optical quality & tracking. It'd also make a very good scope for 22RF, and does have an easy to set zero stop. I'm awaiting delivery of a new V-22 action, and since buying another Cronus 4.5-29x56 scope for it is not in the budget, I'm probably going to mount one of the Ares scopes on it when I get it barreled & bedded into its Manners Elite T4A stock.
