I know that some RSAs have had problems and some have been replaced by Glock, but is the plastic retaining rods in question or a problem? There seems to be a lot of aftermarket stainless and even titanium rods and spring assemblies available, which look quite heafty over the stock set-up! Is this just overkill or should serious shooters conbsider getting one? Thanks! Wanna kill these ads? We can help!
