I am building a 300 Blackout rifle and looking for new glass. I would like to hear about the glass comparison between Vortex PST, Bushnell Elite tactical, Weaver tactical and Sightron tactical. My main concern is glass clarity and quality. The next in order of importance is reliability and repeatable adjustments. All fall in the 600-800 dollar range and right now I am leaning toward the bushnell. All scopes are mil/mil and I am more concern about clarity and adjustments over reticle and ffp/sfp. All scopes I am looking have a max power of 10-15. Any input or known problems with these scopes would be very helpful.
