氣(qi)(qi)動(dong)(dong)(dong)操作(zuo)依(yi)照原理(li)(li)與不同(tong)槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)機(ji)械設計方式(shi)(shi)有分(fen)(fen)為四種(zhong)(zhong)五類：第(di)一種(zhong)(zhong)是(shi)依(yi)賴(lai)活(huo)(huo)(huo)塞(sai)(sai)(sai)原理(li)(li)進(jin)行(xing)槍(qiang)(qiang)(qiang)(qiang)機(ji)運作(zuo)的(de)(de)方式(shi)(shi)，亦即透過(guo)導(dao)(dao)流(liu)使(shi)氣(qi)(qi)體推動(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)(sai)(sai)，活(huo)(huo)(huo)塞(sai)(sai)(sai)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機(ji)，透過(guo)這一串的(de)(de)程(cheng)序完(wan)成(cheng)(cheng)槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)運作(zuo)。然而活(huo)(huo)(huo)塞(sai)(sai)(sai)的(de)(de)運作(zuo)以(yi)行(xing)程(cheng)為主(zhu)，以(yi)行(xing)程(cheng)移動(dong)(dong)(dong)距離(li)的(de)(de)長短劃(hua)分(fen)(fen)，而非以(yi)活(huo)(huo)(huo)塞(sai)(sai)(sai)的(de)(de)重量或(huo)者大(da)小劃(hua)分(fen)(fen)。第(di)二種(zhong)(zhong)是(shi)利用(yong)“收(shou)集”子彈的(de)(de)高(gao)壓氣(qi)(qi)之后(hou)再導(dao)(dao)流(liu)進(jin)入(ru)汽(qi)缸推動(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)(sai)(sai)或(huo)整個槍(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)機(ji)進(jin)行(xing)完(wan)成(cheng)(cheng)槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)運作(zuo)。第(di)三種(zhong)(zhong)是(shi)利用(yong)第(di)二種(zhong)(zhong)“收(shou)集”氣(qi)(qi)體的(de)(de)原理(li)(li)進(jin)行(xing)推動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)(cheng)槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)運作(zuo)。后(hou)一種(zhong)(zhong)是(shi)經由(you)氣(qi)(qi)導(dao)(dao)管(guan)導(dao)(dao)流(liu)氣(qi)(qi)體向后(hou)“吹送”槍(qiang)(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)(cheng)槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)運作(zuo)。因此我們大(da)約可以(yi)分(fen)(fen)為：短行(xing)程(cheng)活(huo)(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長行(xing)程(cheng)活(huo)(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)(qi)井集氣(qi)(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)口增(zeng)壓器(qi)（Muzzle booster）。直噴式(shi)(shi)氣(qi)(qi)動(dong)(dong)(dong)操作(zuo)（Direct impingement；也稱為Direct Gas Action）。
