氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)依(yi)(yi)照原理與不同槍(qiang)枝(zhi)(zhi)的(de)(de)(de)機(ji)械設(she)計方式(shi)有分(fen)(fen)為(wei)四種(zhong)(zhong)五類：第一(yi)種(zhong)(zhong)是(shi)依(yi)(yi)賴活(huo)塞(sai)(sai)原理進行(xing)槍(qiang)機(ji)運(yun)作(zuo)(zuo)(zuo)的(de)(de)(de)方式(shi)，亦即透(tou)(tou)過(guo)導(dao)流使氣(qi)(qi)(qi)體(ti)推動(dong)(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)，活(huo)塞(sai)(sai)連動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)機(ji)，透(tou)(tou)過(guo)這一(yi)串的(de)(de)(de)程(cheng)序完成槍(qiang)枝(zhi)(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。然而活(huo)塞(sai)(sai)的(de)(de)(de)運(yun)作(zuo)(zuo)(zuo)以(yi)行(xing)程(cheng)為(wei)主(zhu)，以(yi)行(xing)程(cheng)移(yi)動(dong)(dong)(dong)(dong)(dong)(dong)距(ju)離的(de)(de)(de)長短劃(hua)分(fen)(fen)，而非以(yi)活(huo)塞(sai)(sai)的(de)(de)(de)重量或者大小劃(hua)分(fen)(fen)。第二種(zhong)(zhong)是(shi)利用(yong)“收集(ji)”子彈的(de)(de)(de)高壓(ya)氣(qi)(qi)(qi)之后再(zai)導(dao)流進入(ru)汽缸推動(dong)(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)或整個槍(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)機(ji)進行(xing)完成槍(qiang)枝(zhi)(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。第三種(zhong)(zhong)是(shi)利用(yong)第二種(zhong)(zhong)“收集(ji)”氣(qi)(qi)(qi)體(ti)的(de)(de)(de)原理進行(xing)推動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)機(ji)完成槍(qiang)枝(zhi)(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。后一(yi)種(zhong)(zhong)是(shi)經由氣(qi)(qi)(qi)導(dao)管(guan)導(dao)流氣(qi)(qi)(qi)體(ti)向后“吹送”槍(qiang)機(ji)完成槍(qiang)枝(zhi)(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。因此(ci)我(wo)們大約(yue)可以(yi)分(fen)(fen)為(wei)：短行(xing)程(cheng)活(huo)塞(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)程(cheng)活(huo)塞(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)(qi)(qi)井集(ji)氣(qi)(qi)(qi)操(cao)作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)口增壓(ya)器（Muzzle booster）。直噴(pen)式(shi)氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
