can anyone confirm or deny that tapco ak mags function in the same super reliable way that e.euro and chinese metal mags do? interest esp in 20r. my search for trades into 20r hungarian tankers has gone nowhere and am considering going us made synthetic route for 20s. tapco g3 triggers are the best,but other us made ak stuff i have experienced (including guns modified here) is crap. no good word heard on promags either. thanks.
