氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)依照原(yuan)理(li)與不(bu)同槍(qiang)枝的(de)機(ji)械設計(ji)方(fang)式(shi)有(you)分為四種五類(lei)：第一種是(shi)依賴(lai)活(huo)塞(sai)原(yuan)理(li)進行槍(qiang)機(ji)運(yun)(yun)作(zuo)(zuo)(zuo)的(de)方(fang)式(shi)，亦即透過導流使氣(qi)體推動(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)，活(huo)塞(sai)連動(dong)(dong)(dong)(dong)(dong)槍(qiang)機(ji)，透過這(zhe)一串的(de)程序完成(cheng)(cheng)(cheng)槍(qiang)枝的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。然而活(huo)塞(sai)的(de)運(yun)(yun)作(zuo)(zuo)(zuo)以行程為主，以行程移動(dong)(dong)(dong)(dong)(dong)距(ju)離的(de)長短劃(hua)分，而非以活(huo)塞(sai)的(de)重量或者大小劃(hua)分。第二種是(shi)利(li)用(yong)“收集(ji)(ji)”子彈的(de)高壓(ya)氣(qi)之后(hou)(hou)再導流進入汽缸推動(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)或整個槍(qiang)管連動(dong)(dong)(dong)(dong)(dong)到槍(qiang)機(ji)進行完成(cheng)(cheng)(cheng)槍(qiang)枝的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。第三種是(shi)利(li)用(yong)第二種“收集(ji)(ji)”氣(qi)體的(de)原(yuan)理(li)進行推動(dong)(dong)(dong)(dong)(dong)槍(qiang)管連動(dong)(dong)(dong)(dong)(dong)槍(qiang)機(ji)完成(cheng)(cheng)(cheng)槍(qiang)枝的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。后(hou)(hou)一種是(shi)經由氣(qi)導管導流氣(qi)體向后(hou)(hou)“吹送”槍(qiang)機(ji)完成(cheng)(cheng)(cheng)槍(qiang)枝的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。因此我們大約可以分為：短行程活(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長行程活(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井(jing)集(ji)(ji)氣(qi)操作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)口增壓(ya)器（Muzzle booster）。直噴式(shi)氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
