Re: Vortex Viper 6.5-20 x 50 vs Viper PST 6.5-24 x 50
I hunt with turrets that don't have caps and have never had a problem with knocking them off zero. I do keep a bikini cover over it during transport just to protect the over all finish.
I like having the option of dialing or using mills for hold over with out having to take caps off.
Just my two cents.
