I spent the past 7 months looking to upgrade my reliable Athlon argos btr 6-24x50. I tried a couple Vortex and even a optika6 4.5-27x50. I realy liked the Riton x5 5-25x50 but I didn't think it meets its msrp. So I finally tried the Arken SH4G2 6-24x50. I'm never looking back, because now that I actually can look back ( looking through the argos I used to love) the Arken image is so bright and huge! These SH4G2 really are fantastic.
