氣(qi)動(dong)(dong)操作(zuo)依照原(yuan)理(li)與不同槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)機(ji)械設計方式(shi)(shi)有(you)分(fen)為四種五類：第(di)一(yi)種是依賴活(huo)塞(sai)(sai)原(yuan)理(li)進(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)(qiang)機(ji)運(yun)(yun)作(zuo)的(de)(de)(de)(de)方式(shi)(shi)，亦即(ji)透過(guo)導(dao)流(liu)使氣(qi)體(ti)(ti)推(tui)動(dong)(dong)活(huo)塞(sai)(sai)，活(huo)塞(sai)(sai)連(lian)動(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機(ji)，透過(guo)這一(yi)串的(de)(de)(de)(de)程(cheng)(cheng)序完(wan)成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)自(zi)動(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)運(yun)(yun)作(zuo)。然(ran)而(er)活(huo)塞(sai)(sai)的(de)(de)(de)(de)運(yun)(yun)作(zuo)以行(xing)(xing)程(cheng)(cheng)為主，以行(xing)(xing)程(cheng)(cheng)移動(dong)(dong)距離的(de)(de)(de)(de)長(chang)短劃分(fen)，而(er)非以活(huo)塞(sai)(sai)的(de)(de)(de)(de)重量或者大小劃分(fen)。第(di)二(er)(er)種是利用“收集(ji)”子彈的(de)(de)(de)(de)高(gao)壓氣(qi)之后再導(dao)流(liu)進(jin)入汽缸推(tui)動(dong)(dong)活(huo)塞(sai)(sai)或整個槍(qiang)(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)機(ji)進(jin)行(xing)(xing)完(wan)成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)自(zi)動(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)運(yun)(yun)作(zuo)。第(di)三種是利用第(di)二(er)(er)種“收集(ji)”氣(qi)體(ti)(ti)的(de)(de)(de)(de)原(yuan)理(li)進(jin)行(xing)(xing)推(tui)動(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)自(zi)動(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)運(yun)(yun)作(zuo)。后一(yi)種是經由氣(qi)導(dao)管導(dao)流(liu)氣(qi)體(ti)(ti)向后“吹送(song)”槍(qiang)(qiang)(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)自(zi)動(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)運(yun)(yun)作(zuo)。因此我們大約可以分(fen)為：短行(xing)(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)傳動(dong)(dong)式(shi)(shi)（Short stroke）。長(chang)行(xing)(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)傳動(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)井(jing)集(ji)氣(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)口增(zeng)壓器（Muzzle booster）。直噴式(shi)(shi)氣(qi)動(dong)(dong)操作(zuo)（Direct impingement；也稱為Direct Gas Action）。
