氣(qi)(qi)(qi)動(dong)(dong)操作(zuo)(zuo)(zuo)依照原理與不同槍(qiang)(qiang)枝的機(ji)械設(she)計方式(shi)有分為(wei)四種五類：第(di)一(yi)種是(shi)(shi)依賴(lai)活(huo)塞(sai)(sai)原理進行(xing)槍(qiang)(qiang)機(ji)運作(zuo)(zuo)(zuo)的方式(shi)，亦(yi)即透(tou)過導(dao)流使氣(qi)(qi)(qi)體推(tui)動(dong)(dong)活(huo)塞(sai)(sai)，活(huo)塞(sai)(sai)連動(dong)(dong)槍(qiang)(qiang)機(ji)，透(tou)過這一(yi)串的程(cheng)(cheng)序完(wan)成槍(qiang)(qiang)枝的自(zi)(zi)動(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)運作(zuo)(zuo)(zuo)。然(ran)而活(huo)塞(sai)(sai)的運作(zuo)(zuo)(zuo)以(yi)行(xing)程(cheng)(cheng)為(wei)主(zhu)，以(yi)行(xing)程(cheng)(cheng)移動(dong)(dong)距離的長(chang)(chang)短劃分，而非(fei)以(yi)活(huo)塞(sai)(sai)的重量(liang)或者大(da)小劃分。第(di)二種是(shi)(shi)利用“收集”子彈的高壓(ya)氣(qi)(qi)(qi)之后再導(dao)流進入汽缸推(tui)動(dong)(dong)活(huo)塞(sai)(sai)或整個槍(qiang)(qiang)管連動(dong)(dong)到(dao)槍(qiang)(qiang)機(ji)進行(xing)完(wan)成槍(qiang)(qiang)枝的自(zi)(zi)動(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)運作(zuo)(zuo)(zuo)。第(di)三(san)種是(shi)(shi)利用第(di)二種“收集”氣(qi)(qi)(qi)體的原理進行(xing)推(tui)動(dong)(dong)槍(qiang)(qiang)管連動(dong)(dong)槍(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)枝的自(zi)(zi)動(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)運作(zuo)(zuo)(zuo)。后一(yi)種是(shi)(shi)經(jing)由氣(qi)(qi)(qi)導(dao)管導(dao)流氣(qi)(qi)(qi)體向后“吹送”槍(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)枝的自(zi)(zi)動(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)運作(zuo)(zuo)(zuo)。因此我們大(da)約可以(yi)分為(wei)：短行(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)傳(chuan)動(dong)(dong)式(shi)（Short stroke）。長(chang)(chang)行(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)傳(chuan)動(dong)(dong)式(shi)（Long stroke）。氣(qi)(qi)(qi)井集氣(qi)(qi)(qi)操作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)口(kou)增壓(ya)器（Muzzle booster）。直噴式(shi)氣(qi)(qi)(qi)動(dong)(dong)操作(zuo)(zuo)(zuo)（Direct impingement；也(ye)稱為(wei)Direct Gas Action）。
