氣(qi)動(dong)(dong)(dong)(dong)操作(zuo)依照原理與不同槍(qiang)(qiang)枝(zhi)的機(ji)械設計方式(shi)有分(fen)為四種(zhong)五類：第(di)一(yi)種(zhong)是依賴活塞(sai)(sai)(sai)原理進(jin)行(xing)槍(qiang)(qiang)機(ji)運(yun)作(zuo)的方式(shi)，亦即透過導流(liu)(liu)使氣(qi)體推(tui)動(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)，活塞(sai)(sai)(sai)連(lian)(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)，透過這一(yi)串的程(cheng)(cheng)序完(wan)成槍(qiang)(qiang)枝(zhi)的自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)作(zuo)。然而活塞(sai)(sai)(sai)的運(yun)作(zuo)以(yi)(yi)行(xing)程(cheng)(cheng)為主，以(yi)(yi)行(xing)程(cheng)(cheng)移(yi)動(dong)(dong)(dong)(dong)距離的長短劃(hua)(hua)分(fen)，而非以(yi)(yi)活塞(sai)(sai)(sai)的重量或(huo)者大(da)小劃(hua)(hua)分(fen)。第(di)二種(zhong)是利用“收(shou)集(ji)(ji)”子彈的高壓氣(qi)之后(hou)再(zai)導流(liu)(liu)進(jin)入汽缸(gang)推(tui)動(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)或(huo)整個槍(qiang)(qiang)管連(lian)(lian)動(dong)(dong)(dong)(dong)到(dao)槍(qiang)(qiang)機(ji)進(jin)行(xing)完(wan)成槍(qiang)(qiang)枝(zhi)的自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)作(zuo)。第(di)三種(zhong)是利用第(di)二種(zhong)“收(shou)集(ji)(ji)”氣(qi)體的原理進(jin)行(xing)推(tui)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)管連(lian)(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)枝(zhi)的自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)作(zuo)。后(hou)一(yi)種(zhong)是經(jing)由氣(qi)導管導流(liu)(liu)氣(qi)體向后(hou)“吹送(song)”槍(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)枝(zhi)的自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)作(zuo)。因(yin)此我們大(da)約可以(yi)(yi)分(fen)為：短行(xing)程(cheng)(cheng)活塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)程(cheng)(cheng)活塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井集(ji)(ji)氣(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)口(kou)增(zeng)壓器（Muzzle booster）。直噴(pen)式(shi)氣(qi)動(dong)(dong)(dong)(dong)操作(zuo)（Direct impingement；也稱為Direct Gas Action）。
