I bought a diamondback tactical 6-24 shortly after they were released and hit the main stream. The reason I say it like that is I have no idea if any improvements have been made over the years, I have an original.
The turrets are mushy and don't always line up with the marks exactly, however it works, and I can hit shit with it out to 1000 yards
It also has a good amount of chromatic aberration
It dials true
no zero stop
I then bought a GEN 1 Athlon Argos BTR 6-24 (but at the end of life for the gen 1, I know improvements were made and are different versions of the gen 1, I got a final with all improvements). Turrets are MUCH better and more crisp, glass appears better too
I have dialed it all over 100-600 yards and never had any issues. I got the gen 1 on closeout for $270, it was a STEAL
zero stop is plastic washers, sort of cheap, but works
I can hit shit out to 1000 yards with this scope too
I then bought a GEN 2 Athlon Argos BTR 6-24 Turrets are even better, very positive click and accurate
glass is the same as the gen 1
zero stop is much improved (still low budget) built in system simple and effective
I paid $370 for this one, I got a better deal on the gen 1, but this one is worth the money I spent, it is 'improved'
I bought one vortex diamondback and 2 Athlons after having used both, when I go to buy a 3rd budget scope, it will be another Athlon. not that the diamondback is bad, but you can get the athlon for less and it is just a little better the whole way around. Unless something about the diamondback is screaming your name, you know which to buy at this point
