氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)依(yi)照原理與不同槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)機(ji)(ji)械設計方(fang)式有分為四種五類：第(di)一種是(shi)依(yi)賴活(huo)(huo)塞(sai)原理進(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)運(yun)(yun)作(zuo)的(de)方(fang)式，亦即透(tou)過(guo)(guo)導流(liu)使氣(qi)體推動(dong)(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)，活(huo)(huo)塞(sai)連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)，透(tou)過(guo)(guo)這一串的(de)程(cheng)(cheng)序完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。然而活(huo)(huo)塞(sai)的(de)運(yun)(yun)作(zuo)以(yi)行(xing)(xing)程(cheng)(cheng)為主，以(yi)行(xing)(xing)程(cheng)(cheng)移動(dong)(dong)(dong)(dong)(dong)距離的(de)長短劃(hua)分，而非以(yi)活(huo)(huo)塞(sai)的(de)重量(liang)或(huo)(huo)者大小劃(hua)分。第(di)二(er)(er)種是(shi)利用“收集”子彈的(de)高壓(ya)(ya)氣(qi)之后(hou)再導流(liu)進(jin)入汽(qi)缸推動(dong)(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)或(huo)(huo)整(zheng)個槍(qiang)(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)進(jin)行(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。第(di)三種是(shi)利用第(di)二(er)(er)種“收集”氣(qi)體的(de)原理進(jin)行(xing)(xing)推動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。后(hou)一種是(shi)經由(you)氣(qi)導管導流(liu)氣(qi)體向后(hou)“吹送”槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。因此我們大約(yue)可以(yi)分為：短行(xing)(xing)程(cheng)(cheng)活(huo)(huo)塞(sai)傳動(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程(cheng)(cheng)活(huo)(huo)塞(sai)傳動(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)井集氣(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)口增壓(ya)(ya)器（Muzzle booster）。直噴式氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)（Direct impingement；也稱為Direct Gas Action）。
