氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)依(yi)照原理與不同槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)機(ji)械(xie)設計方式(shi)有分為(wei)四種(zhong)五類：第(di)一種(zhong)是(shi)(shi)依(yi)賴(lai)活(huo)(huo)(huo)塞(sai)(sai)(sai)原理進行(xing)槍(qiang)(qiang)(qiang)機(ji)運(yun)(yun)作(zuo)(zuo)(zuo)的(de)(de)方式(shi)，亦即(ji)透(tou)過導(dao)流使氣(qi)體(ti)推動(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)(sai)(sai)，活(huo)(huo)(huo)塞(sai)(sai)(sai)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透(tou)過這(zhe)一串(chuan)的(de)(de)程(cheng)序完(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。然(ran)而(er)活(huo)(huo)(huo)塞(sai)(sai)(sai)的(de)(de)運(yun)(yun)作(zuo)(zuo)(zuo)以(yi)行(xing)程(cheng)為(wei)主，以(yi)行(xing)程(cheng)移動(dong)(dong)(dong)距(ju)離的(de)(de)長短劃分，而(er)非以(yi)活(huo)(huo)(huo)塞(sai)(sai)(sai)的(de)(de)重量或者大小劃分。第(di)二(er)種(zhong)是(shi)(shi)利用(yong)“收(shou)集(ji)”子彈(dan)的(de)(de)高壓氣(qi)之后(hou)再(zai)導(dao)流進入汽缸推動(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)(sai)(sai)或整(zheng)個槍(qiang)(qiang)(qiang)管(guan)(guan)連(lian)動(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進行(xing)完(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。第(di)三(san)種(zhong)是(shi)(shi)利用(yong)第(di)二(er)種(zhong)“收(shou)集(ji)”氣(qi)體(ti)的(de)(de)原理進行(xing)推動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管(guan)(guan)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。后(hou)一種(zhong)是(shi)(shi)經由氣(qi)導(dao)管(guan)(guan)導(dao)流氣(qi)體(ti)向后(hou)“吹送”槍(qiang)(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。因此我們大約(yue)可以(yi)分為(wei)：短行(xing)程(cheng)活(huo)(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)程(cheng)活(huo)(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井集(ji)氣(qi)操(cao)作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直噴式(shi)氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
