If you doubt the Argos BTR's track, let me tell you otherwise.
I won my division at state for the 3rd year in a row with one on my USFT precharged air rifle in Field Target air rifle competition.
On centerfires I've made cold bore shots on steel out to 981Y, a friend does with his as well.
The Midas TAC is a great scope, I have the 4-16 on my AR. For a basic scope and standard reticle it's the best on the market for the money period.
Though my favorite sub $1000 scope is the Ares BTR 4.5-27, mostly because of that awesome .2 mil reticle, but the scope plain works well.
