氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)依照原(yuan)理與不同槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)機(ji)械設計方式(shi)(shi)有(you)分(fen)為四種(zhong)(zhong)五(wu)類：第一種(zhong)(zhong)是(shi)依賴活(huo)(huo)(huo)塞原(yuan)理進(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)運(yun)(yun)作(zuo)(zuo)的(de)(de)方式(shi)(shi)，亦即透過導流使(shi)氣(qi)體(ti)推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)(huo)(huo)塞，活(huo)(huo)(huo)塞連動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)，透過這一串的(de)(de)程(cheng)(cheng)序(xu)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。然而(er)活(huo)(huo)(huo)塞的(de)(de)運(yun)(yun)作(zuo)(zuo)以行(xing)(xing)程(cheng)(cheng)為主，以行(xing)(xing)程(cheng)(cheng)移(yi)動(dong)(dong)(dong)(dong)(dong)距離的(de)(de)長(chang)短劃(hua)分(fen)，而(er)非以活(huo)(huo)(huo)塞的(de)(de)重量或(huo)者大小劃(hua)分(fen)。第二(er)種(zhong)(zhong)是(shi)利用(yong)“收集”子彈的(de)(de)高壓氣(qi)之后再導流進(jin)入(ru)汽缸推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)(huo)(huo)塞或(huo)整(zheng)個槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)進(jin)行(xing)(xing)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。第三種(zhong)(zhong)是(shi)利用(yong)第二(er)種(zhong)(zhong)“收集”氣(qi)體(ti)的(de)(de)原(yuan)理進(jin)行(xing)(xing)推(tui)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。后一種(zhong)(zhong)是(shi)經由氣(qi)導管(guan)導流氣(qi)體(ti)向后“吹(chui)送(song)”槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。因此我們大約可以分(fen)為：短行(xing)(xing)程(cheng)(cheng)活(huo)(huo)(huo)塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長(chang)行(xing)(xing)程(cheng)(cheng)活(huo)(huo)(huo)塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)井集氣(qi)操作(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)(qiang)口(kou)增壓器(qi)（Muzzle booster）。直噴式(shi)(shi)氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)（Direct impingement；也稱(cheng)為Direct Gas Action）。
