氣(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)依照原理與不(bu)同槍(qiang)枝的(de)(de)(de)(de)機(ji)械(xie)設計方式有分(fen)(fen)為四種五類：第一種是(shi)依賴活(huo)塞原理進行(xing)槍(qiang)機(ji)運(yun)(yun)(yun)(yun)作(zuo)(zuo)的(de)(de)(de)(de)方式，亦即透(tou)過導(dao)流(liu)使氣(qi)(qi)體(ti)(ti)推(tui)(tui)動(dong)(dong)(dong)(dong)活(huo)塞，活(huo)塞連(lian)動(dong)(dong)(dong)(dong)槍(qiang)機(ji)，透(tou)過這(zhe)一串(chuan)的(de)(de)(de)(de)程(cheng)(cheng)序完成(cheng)槍(qiang)枝的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作(zuo)(zuo)。然(ran)而活(huo)塞的(de)(de)(de)(de)運(yun)(yun)(yun)(yun)作(zuo)(zuo)以行(xing)程(cheng)(cheng)為主(zhu)，以行(xing)程(cheng)(cheng)移(yi)動(dong)(dong)(dong)(dong)距(ju)離的(de)(de)(de)(de)長(chang)短劃分(fen)(fen)，而非以活(huo)塞的(de)(de)(de)(de)重量或者大(da)小劃分(fen)(fen)。第二種是(shi)利用(yong)“收集”子彈的(de)(de)(de)(de)高壓氣(qi)(qi)之(zhi)后再導(dao)流(liu)進入汽(qi)缸(gang)推(tui)(tui)動(dong)(dong)(dong)(dong)活(huo)塞或整個槍(qiang)管連(lian)動(dong)(dong)(dong)(dong)到槍(qiang)機(ji)進行(xing)完成(cheng)槍(qiang)枝的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作(zuo)(zuo)。第三種是(shi)利用(yong)第二種“收集”氣(qi)(qi)體(ti)(ti)的(de)(de)(de)(de)原理進行(xing)推(tui)(tui)動(dong)(dong)(dong)(dong)槍(qiang)管連(lian)動(dong)(dong)(dong)(dong)槍(qiang)機(ji)完成(cheng)槍(qiang)枝的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作(zuo)(zuo)。后一種是(shi)經(jing)由氣(qi)(qi)導(dao)管導(dao)流(liu)氣(qi)(qi)體(ti)(ti)向后“吹送(song)”槍(qiang)機(ji)完成(cheng)槍(qiang)枝的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作(zuo)(zuo)。因此(ci)我們(men)大(da)約可以分(fen)(fen)為：短行(xing)程(cheng)(cheng)活(huo)塞傳(chuan)動(dong)(dong)(dong)(dong)式（Short stroke）。長(chang)行(xing)程(cheng)(cheng)活(huo)塞傳(chuan)動(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)井集氣(qi)(qi)操(cao)作(zuo)(zuo)（Gas trap）。槍(qiang)口增壓器(qi)（Muzzle booster）。直噴式氣(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
