Have a few 2.5-8x vari-x III, one on a .376 steyr that’s been beat around, flown 5 times through airport gorilla baggage handlers, rode on ATV’s etc and never lost zero or failed. For its intended use, I haven’t felt the need to trade it out for anything else. Definitely not a Burris FFII. Trijicon 3-9x is a good option depending on use, I have one on a .223AI that gets back door garden pest control duty.
