氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)依(yi)照原(yuan)理(li)與不同(tong)槍(qiang)枝(zhi)(zhi)的(de)(de)(de)機(ji)(ji)械設計(ji)方式(shi)(shi)有分(fen)為(wei)(wei)四種(zhong)五類：第一種(zhong)是依(yi)賴活塞原(yuan)理(li)進行(xing)槍(qiang)機(ji)(ji)運(yun)(yun)作(zuo)(zuo)的(de)(de)(de)方式(shi)(shi)，亦即透過導流使(shi)氣(qi)體推動(dong)(dong)(dong)活塞，活塞連(lian)動(dong)(dong)(dong)槍(qiang)機(ji)(ji)，透過這一串(chuan)的(de)(de)(de)程(cheng)序完(wan)成槍(qiang)枝(zhi)(zhi)的(de)(de)(de)自動(dong)(dong)(dong)/半自動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。然而(er)活塞的(de)(de)(de)運(yun)(yun)作(zuo)(zuo)以(yi)(yi)行(xing)程(cheng)為(wei)(wei)主，以(yi)(yi)行(xing)程(cheng)移動(dong)(dong)(dong)距離的(de)(de)(de)長短劃分(fen)，而(er)非以(yi)(yi)活塞的(de)(de)(de)重量(liang)或者大小劃分(fen)。第二種(zhong)是利用(yong)“收(shou)(shou)集”子彈的(de)(de)(de)高壓(ya)氣(qi)之后再導流進入(ru)汽缸推動(dong)(dong)(dong)活塞或整個槍(qiang)管連(lian)動(dong)(dong)(dong)到槍(qiang)機(ji)(ji)進行(xing)完(wan)成槍(qiang)枝(zhi)(zhi)的(de)(de)(de)自動(dong)(dong)(dong)/半自動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。第三種(zhong)是利用(yong)第二種(zhong)“收(shou)(shou)集”氣(qi)體的(de)(de)(de)原(yuan)理(li)進行(xing)推動(dong)(dong)(dong)槍(qiang)管連(lian)動(dong)(dong)(dong)槍(qiang)機(ji)(ji)完(wan)成槍(qiang)枝(zhi)(zhi)的(de)(de)(de)自動(dong)(dong)(dong)/半自動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。后一種(zhong)是經由(you)氣(qi)導管導流氣(qi)體向(xiang)后“吹送”槍(qiang)機(ji)(ji)完(wan)成槍(qiang)枝(zhi)(zhi)的(de)(de)(de)自動(dong)(dong)(dong)/半自動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。因此我(wo)們大約可以(yi)(yi)分(fen)為(wei)(wei)：短行(xing)程(cheng)活塞傳動(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長行(xing)程(cheng)活塞傳動(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)井集氣(qi)操(cao)作(zuo)(zuo)（Gas trap）。槍(qiang)口增壓(ya)器（Muzzle booster）。直(zhi)噴式(shi)(shi)氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)（Direct impingement；也(ye)稱為(wei)(wei)Direct Gas Action）。
