氣(qi)動(dong)(dong)(dong)操作(zuo)(zuo)依照原理(li)與(yu)不(bu)同槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)機(ji)(ji)械設計方式(shi)有分為四種(zhong)五(wu)類(lei)：第(di)一種(zhong)是(shi)依賴(lai)活塞(sai)(sai)原理(li)進(jin)(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)運作(zuo)(zuo)的(de)方式(shi)，亦(yi)即透(tou)(tou)過導(dao)流(liu)使氣(qi)體(ti)推動(dong)(dong)(dong)活塞(sai)(sai)，活塞(sai)(sai)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)，透(tou)(tou)過這一串(chuan)的(de)程(cheng)(cheng)(cheng)(cheng)序完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作(zuo)(zuo)。然而活塞(sai)(sai)的(de)運作(zuo)(zuo)以(yi)行(xing)(xing)程(cheng)(cheng)(cheng)(cheng)為主，以(yi)行(xing)(xing)程(cheng)(cheng)(cheng)(cheng)移動(dong)(dong)(dong)距(ju)離的(de)長短劃(hua)分，而非以(yi)活塞(sai)(sai)的(de)重量或(huo)者大小劃(hua)分。第(di)二(er)種(zhong)是(shi)利用(yong)“收(shou)集(ji)”子彈的(de)高壓(ya)氣(qi)之后(hou)(hou)再(zai)導(dao)流(liu)進(jin)(jin)入汽缸推動(dong)(dong)(dong)活塞(sai)(sai)或(huo)整(zheng)個槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)到(dao)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)進(jin)(jin)行(xing)(xing)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作(zuo)(zuo)。第(di)三種(zhong)是(shi)利用(yong)第(di)二(er)種(zhong)“收(shou)集(ji)”氣(qi)體(ti)的(de)原理(li)進(jin)(jin)行(xing)(xing)推動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作(zuo)(zuo)。后(hou)(hou)一種(zhong)是(shi)經由氣(qi)導(dao)管(guan)導(dao)流(liu)氣(qi)體(ti)向(xiang)后(hou)(hou)“吹送”槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作(zuo)(zuo)。因此我們大約可以(yi)分為：短行(xing)(xing)程(cheng)(cheng)(cheng)(cheng)活塞(sai)(sai)傳動(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)(xing)程(cheng)(cheng)(cheng)(cheng)活塞(sai)(sai)傳動(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井集(ji)氣(qi)操作(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)(qiang)口增壓(ya)器（Muzzle booster）。直噴式(shi)氣(qi)動(dong)(dong)(dong)操作(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
