氣(qi)動(dong)(dong)(dong)操(cao)(cao)作依照原(yuan)理與不同槍(qiang)(qiang)(qiang)枝(zhi)的(de)機(ji)械設計方式有(you)分(fen)為四種(zhong)五類：第(di)一種(zhong)是依賴活(huo)塞(sai)(sai)原(yuan)理進(jin)(jin)(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)運(yun)(yun)(yun)作的(de)方式，亦即透(tou)過(guo)導(dao)流(liu)使氣(qi)體推(tui)動(dong)(dong)(dong)活(huo)塞(sai)(sai)，活(huo)塞(sai)(sai)連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透(tou)過(guo)這一串的(de)程(cheng)(cheng)序(xu)完(wan)(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)(yun)作。然而活(huo)塞(sai)(sai)的(de)運(yun)(yun)(yun)作以(yi)(yi)(yi)行(xing)(xing)程(cheng)(cheng)為主，以(yi)(yi)(yi)行(xing)(xing)程(cheng)(cheng)移(yi)動(dong)(dong)(dong)距離的(de)長短(duan)劃(hua)分(fen)，而非(fei)以(yi)(yi)(yi)活(huo)塞(sai)(sai)的(de)重量或(huo)(huo)者(zhe)大小劃(hua)分(fen)。第(di)二(er)種(zhong)是利(li)用“收集(ji)”子(zi)彈的(de)高壓(ya)氣(qi)之后(hou)(hou)再(zai)導(dao)流(liu)進(jin)(jin)(jin)入汽(qi)缸推(tui)動(dong)(dong)(dong)活(huo)塞(sai)(sai)或(huo)(huo)整個槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進(jin)(jin)(jin)行(xing)(xing)完(wan)(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)(yun)作。第(di)三(san)種(zhong)是利(li)用第(di)二(er)種(zhong)“收集(ji)”氣(qi)體的(de)原(yuan)理進(jin)(jin)(jin)行(xing)(xing)推(tui)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完(wan)(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)(yun)作。后(hou)(hou)一種(zhong)是經由氣(qi)導(dao)管導(dao)流(liu)氣(qi)體向后(hou)(hou)“吹送”槍(qiang)(qiang)(qiang)機(ji)完(wan)(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)(yun)作。因此我們大約可以(yi)(yi)(yi)分(fen)為：短(duan)行(xing)(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)傳(chuan)動(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)傳(chuan)動(dong)(dong)(dong)式（Long stroke）。氣(qi)井集(ji)氣(qi)操(cao)(cao)作（Gas trap）。槍(qiang)(qiang)(qiang)口增壓(ya)器（Muzzle booster）。直噴式氣(qi)動(dong)(dong)(dong)操(cao)(cao)作（Direct impingement；也稱(cheng)為Direct Gas Action）。
