I'm not interested in using irons, spending the time and money mastering them, but that's just me.
Most rifle shooters will shoot a RDS better if they master shooting with iron sights first. The fundamentals of rifle marksmanship are the same for both irons and optics. Irons are less forgiving so they require more consistency and focus to shoot well. The consistency and focus irons help shooters develop make the advantages of RDS and optics easier to maximize.
Take cheek weld for example. With irons, a consistent chekweld is essential while with a RDS head position has broad parameters. Putting your head in the same psoition makes putting the dot on target very natural and easy. While varying head position complicates finding the dot on the target. When fractions of a second count, simplicity reigns supreme.
