氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)(zuo)依(yi)照原理(li)與(yu)不同槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)機(ji)(ji)(ji)械設計方式有(you)分(fen)為四種五類：第(di)一種是依(yi)賴活(huo)塞(sai)原理(li)進行(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)運(yun)(yun)作(zuo)(zuo)(zuo)(zuo)的(de)方式，亦即透過(guo)導(dao)(dao)流使(shi)氣(qi)(qi)(qi)體(ti)推動(dong)(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)，活(huo)塞(sai)連動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)，透過(guo)這(zhe)一串的(de)程(cheng)序完(wan)成(cheng)(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)自動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)(zuo)。然而活(huo)塞(sai)的(de)運(yun)(yun)作(zuo)(zuo)(zuo)(zuo)以行(xing)(xing)程(cheng)為主，以行(xing)(xing)程(cheng)移(yi)動(dong)(dong)(dong)(dong)(dong)(dong)距離的(de)長短(duan)劃分(fen)，而非以活(huo)塞(sai)的(de)重量或者(zhe)大小劃分(fen)。第(di)二種是利用(yong)“收(shou)集”子彈的(de)高(gao)壓氣(qi)(qi)(qi)之后再導(dao)(dao)流進入汽缸推動(dong)(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)或整個(ge)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)進行(xing)(xing)完(wan)成(cheng)(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)自動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)(zuo)。第(di)三種是利用(yong)第(di)二種“收(shou)集”氣(qi)(qi)(qi)體(ti)的(de)原理(li)進行(xing)(xing)推動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)完(wan)成(cheng)(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)自動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)(zuo)。后一種是經由氣(qi)(qi)(qi)導(dao)(dao)管導(dao)(dao)流氣(qi)(qi)(qi)體(ti)向后“吹送”槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)完(wan)成(cheng)(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)自動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)(zuo)。因(yin)此我們(men)大約(yue)可以分(fen)為：短(duan)行(xing)(xing)程(cheng)活(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程(cheng)活(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)(qi)井集氣(qi)(qi)(qi)操(cao)作(zuo)(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口(kou)增壓器（Muzzle booster）。直噴式氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
