氣(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)依照(zhao)原理(li)與(yu)不(bu)同槍枝(zhi)的(de)(de)機械設計(ji)方式(shi)有分為(wei)(wei)四(si)種(zhong)五類：第一(yi)(yi)種(zhong)是依賴活(huo)(huo)(huo)(huo)(huo)塞原理(li)進(jin)行(xing)(xing)槍機運(yun)(yun)(yun)(yun)作(zuo)(zuo)(zuo)的(de)(de)方式(shi)，亦(yi)即透過導(dao)流使氣(qi)體(ti)推動(dong)(dong)(dong)(dong)活(huo)(huo)(huo)(huo)(huo)塞，活(huo)(huo)(huo)(huo)(huo)塞連(lian)動(dong)(dong)(dong)(dong)槍機，透過這一(yi)(yi)串(chuan)的(de)(de)程(cheng)序完(wan)(wan)成槍枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作(zuo)(zuo)(zuo)。然而活(huo)(huo)(huo)(huo)(huo)塞的(de)(de)運(yun)(yun)(yun)(yun)作(zuo)(zuo)(zuo)以(yi)(yi)行(xing)(xing)程(cheng)為(wei)(wei)主(zhu)，以(yi)(yi)行(xing)(xing)程(cheng)移動(dong)(dong)(dong)(dong)距離的(de)(de)長短(duan)劃分，而非以(yi)(yi)活(huo)(huo)(huo)(huo)(huo)塞的(de)(de)重(zhong)量或者大小劃分。第二(er)種(zhong)是利(li)(li)用(yong)“收集”子彈(dan)的(de)(de)高壓(ya)(ya)氣(qi)之后再導(dao)流進(jin)入汽缸推動(dong)(dong)(dong)(dong)活(huo)(huo)(huo)(huo)(huo)塞或整個槍管(guan)連(lian)動(dong)(dong)(dong)(dong)到槍機進(jin)行(xing)(xing)完(wan)(wan)成槍枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作(zuo)(zuo)(zuo)。第三種(zhong)是利(li)(li)用(yong)第二(er)種(zhong)“收集”氣(qi)體(ti)的(de)(de)原理(li)進(jin)行(xing)(xing)推動(dong)(dong)(dong)(dong)槍管(guan)連(lian)動(dong)(dong)(dong)(dong)槍機完(wan)(wan)成槍枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作(zuo)(zuo)(zuo)。后一(yi)(yi)種(zhong)是經由(you)氣(qi)導(dao)管(guan)導(dao)流氣(qi)體(ti)向后“吹送(song)”槍機完(wan)(wan)成槍枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作(zuo)(zuo)(zuo)。因此我們大約(yue)可以(yi)(yi)分為(wei)(wei)：短(duan)行(xing)(xing)程(cheng)活(huo)(huo)(huo)(huo)(huo)塞傳動(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)(xing)程(cheng)活(huo)(huo)(huo)(huo)(huo)塞傳動(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井集氣(qi)操(cao)作(zuo)(zuo)(zuo)（Gas trap）。槍口(kou)增壓(ya)(ya)器（Muzzle booster）。直(zhi)噴(pen)式(shi)氣(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)（Direct impingement；也稱為(wei)(wei)Direct Gas Action）。
