氣(qi)動(dong)(dong)(dong)(dong)操(cao)(cao)作(zuo)(zuo)依照原(yuan)理(li)與不同槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)機(ji)械(xie)設計(ji)方式有分(fen)為四種五類：第(di)一(yi)種是依賴活(huo)塞(sai)(sai)(sai)原(yuan)理(li)進(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)運(yun)(yun)(yun)作(zuo)(zuo)的(de)(de)(de)方式，亦即透過導流(liu)使氣(qi)體(ti)推動(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)，活(huo)塞(sai)(sai)(sai)連動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透過這一(yi)串(chuan)的(de)(de)(de)程序完成(cheng)(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)(zuo)。然而(er)活(huo)塞(sai)(sai)(sai)的(de)(de)(de)運(yun)(yun)(yun)作(zuo)(zuo)以行(xing)(xing)程為主，以行(xing)(xing)程移動(dong)(dong)(dong)(dong)距離的(de)(de)(de)長(chang)短(duan)劃(hua)分(fen)，而(er)非以活(huo)塞(sai)(sai)(sai)的(de)(de)(de)重量或者大小劃(hua)分(fen)。第(di)二種是利用(yong)“收集(ji)(ji)”子彈的(de)(de)(de)高壓氣(qi)之后(hou)(hou)(hou)再導流(liu)進(jin)入汽缸推動(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)或整個(ge)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進(jin)行(xing)(xing)完成(cheng)(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)(zuo)。第(di)三(san)種是利用(yong)第(di)二種“收集(ji)(ji)”氣(qi)體(ti)的(de)(de)(de)原(yuan)理(li)進(jin)行(xing)(xing)推動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完成(cheng)(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)(zuo)。后(hou)(hou)(hou)一(yi)種是經由氣(qi)導管導流(liu)氣(qi)體(ti)向后(hou)(hou)(hou)“吹送(song)”槍(qiang)(qiang)(qiang)機(ji)完成(cheng)(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)(zuo)。因此我們大約可以分(fen)為：短(duan)行(xing)(xing)程活(huo)塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式（Short stroke）。長(chang)行(xing)(xing)程活(huo)塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)井集(ji)(ji)氣(qi)操(cao)(cao)作(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直(zhi)噴式氣(qi)動(dong)(dong)(dong)(dong)操(cao)(cao)作(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
