The Argos is not a good comparison to the PST2. The Ares is more comparable. The Argos is proven to be a great scope for the money, but the 8-32 power will be very limiting in eye relief and field of view. Also total elevation adjustment is less than the 6-24 power version. That particular scope design is used by several manufacturers and it's proven to track fairly reliably. I would definitely recommend the 6-24 power version. But here's a little hint, they are coming out with a gen 2 version of the Argos and the Ares, both with upgraded turret feel. So, the current Argos and Ares will be cheap in 2020. Both are good scopes, with the Ares beating the Argos in every category.
