氣(qi)動(dong)(dong)(dong)(dong)操作(zuo)(zuo)依(yi)照原理與不同槍(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)機械設計方式(shi)有分(fen)為(wei)四種(zhong)(zhong)五類(lei)：第(di)(di)一種(zhong)(zhong)是(shi)依(yi)賴活塞原理進行(xing)(xing)槍(qiang)機運(yun)(yun)作(zuo)(zuo)的(de)(de)(de)(de)方式(shi)，亦即透過(guo)導(dao)流(liu)使氣(qi)體(ti)推動(dong)(dong)(dong)(dong)活塞，活塞連動(dong)(dong)(dong)(dong)槍(qiang)機，透過(guo)這一串的(de)(de)(de)(de)程序完(wan)成(cheng)槍(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。然而(er)活塞的(de)(de)(de)(de)運(yun)(yun)作(zuo)(zuo)以行(xing)(xing)程為(wei)主，以行(xing)(xing)程移動(dong)(dong)(dong)(dong)距離的(de)(de)(de)(de)長短劃(hua)分(fen)，而(er)非以活塞的(de)(de)(de)(de)重量(liang)或(huo)(huo)者(zhe)大小劃(hua)分(fen)。第(di)(di)二種(zhong)(zhong)是(shi)利(li)(li)用“收集(ji)”子彈的(de)(de)(de)(de)高(gao)壓(ya)氣(qi)之(zhi)后再導(dao)流(liu)進入汽缸推動(dong)(dong)(dong)(dong)活塞或(huo)(huo)整個槍(qiang)管連動(dong)(dong)(dong)(dong)到槍(qiang)機進行(xing)(xing)完(wan)成(cheng)槍(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。第(di)(di)三種(zhong)(zhong)是(shi)利(li)(li)用第(di)(di)二種(zhong)(zhong)“收集(ji)”氣(qi)體(ti)的(de)(de)(de)(de)原理進行(xing)(xing)推動(dong)(dong)(dong)(dong)槍(qiang)管連動(dong)(dong)(dong)(dong)槍(qiang)機完(wan)成(cheng)槍(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。后一種(zhong)(zhong)是(shi)經由氣(qi)導(dao)管導(dao)流(liu)氣(qi)體(ti)向后“吹送”槍(qiang)機完(wan)成(cheng)槍(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。因此我們(men)大約可以分(fen)為(wei)：短行(xing)(xing)程活塞傳動(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)(xing)程活塞傳動(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井集(ji)氣(qi)操作(zuo)(zuo)（Gas trap）。槍(qiang)口增(zeng)壓(ya)器（Muzzle booster）。直噴(pen)式(shi)氣(qi)動(dong)(dong)(dong)(dong)操作(zuo)(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
