氣(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)依照(zhao)原(yuan)理與不(bu)同槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)(de)機(ji)械設(she)計方式(shi)(shi)有(you)分為四種(zhong)五類：第一種(zhong)是依賴活(huo)(huo)塞(sai)(sai)(sai)原(yuan)理進行(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)運作(zuo)的(de)(de)方式(shi)(shi)，亦(yi)即透過導流(liu)使氣(qi)(qi)體推動(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)(sai)(sai)，活(huo)(huo)塞(sai)(sai)(sai)連(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透過這一串的(de)(de)程(cheng)序(xu)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)。然(ran)而活(huo)(huo)塞(sai)(sai)(sai)的(de)(de)運作(zuo)以(yi)行(xing)(xing)程(cheng)為主，以(yi)行(xing)(xing)程(cheng)移動(dong)(dong)(dong)(dong)距離的(de)(de)長(chang)短劃分，而非以(yi)活(huo)(huo)塞(sai)(sai)(sai)的(de)(de)重量或者(zhe)大小劃分。第二種(zhong)是利用(yong)“收集”子(zi)彈的(de)(de)高(gao)壓(ya)氣(qi)(qi)之后(hou)再導流(liu)進入汽缸推動(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)(sai)(sai)或整(zheng)個槍(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)到(dao)槍(qiang)(qiang)(qiang)機(ji)進行(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)。第三種(zhong)是利用(yong)第二種(zhong)“收集”氣(qi)(qi)體的(de)(de)原(yuan)理進行(xing)(xing)推動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)。后(hou)一種(zhong)是經由(you)氣(qi)(qi)導管導流(liu)氣(qi)(qi)體向(xiang)后(hou)“吹送”槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)。因此我們大約可(ke)以(yi)分為：短行(xing)(xing)程(cheng)活(huo)(huo)塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長(chang)行(xing)(xing)程(cheng)活(huo)(huo)塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)(qi)井(jing)集氣(qi)(qi)操(cao)作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口增(zeng)壓(ya)器（Muzzle booster）。直噴式(shi)(shi)氣(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)（Direct impingement；也稱為Direct Gas Action）。
