氣(qi)動(dong)(dong)(dong)(dong)(dong)操(cao)作依照原理與(yu)不同槍(qiang)(qiang)(qiang)枝的機(ji)(ji)械設計方(fang)式有分(fen)(fen)為(wei)四種(zhong)(zhong)(zhong)(zhong)五類：第(di)一種(zhong)(zhong)(zhong)(zhong)是依賴活(huo)塞(sai)(sai)(sai)原理進(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)(ji)運作的方(fang)式，亦即(ji)透(tou)過導流(liu)使氣(qi)體(ti)推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)，活(huo)塞(sai)(sai)(sai)連動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)，透(tou)過這一串的程(cheng)(cheng)序完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運作。然而活(huo)塞(sai)(sai)(sai)的運作以行(xing)(xing)程(cheng)(cheng)為(wei)主，以行(xing)(xing)程(cheng)(cheng)移動(dong)(dong)(dong)(dong)(dong)距離的長短(duan)劃(hua)分(fen)(fen)，而非以活(huo)塞(sai)(sai)(sai)的重量或(huo)者大小劃(hua)分(fen)(fen)。第(di)二種(zhong)(zhong)(zhong)(zhong)是利用(yong)“收(shou)(shou)集(ji)”子彈的高壓氣(qi)之后(hou)再導流(liu)進(jin)入汽缸(gang)推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)或(huo)整個(ge)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)(dong)到(dao)槍(qiang)(qiang)(qiang)機(ji)(ji)進(jin)行(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運作。第(di)三(san)種(zhong)(zhong)(zhong)(zhong)是利用(yong)第(di)二種(zhong)(zhong)(zhong)(zhong)“收(shou)(shou)集(ji)”氣(qi)體(ti)的原理進(jin)行(xing)(xing)推(tui)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運作。后(hou)一種(zhong)(zhong)(zhong)(zhong)是經由氣(qi)導管導流(liu)氣(qi)體(ti)向后(hou)“吹送”槍(qiang)(qiang)(qiang)機(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運作。因此我們大約可以分(fen)(fen)為(wei)：短(duan)行(xing)(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)井集(ji)氣(qi)操(cao)作（Gas trap）。槍(qiang)(qiang)(qiang)口(kou)增(zeng)壓器（Muzzle booster）。直噴(pen)式氣(qi)動(dong)(dong)(dong)(dong)(dong)操(cao)作（Direct impingement；也稱為(wei)Direct Gas Action）。
