Fixed sights on semi-autos are so low any filing will practically wipe the sight off the pistol. A higher rear sight for the SAR is hard to find in this area.
I dont own any eastern bloc guns. For western made stuff, finding and swapping out sights is fairly easy, and pretty common when taking a stock gun and tricking it out for competitive shooting.
At any rate, as a pistol shooter myself, I’m not knocking anyones preferences for guns. I just thought the whole ‘accuracy’ thing from the article was silly, since relative to rifle shooting, pistol accuracy is kind of a joke and a ‘dont care’ given the close in short ranges most common to it.
