氣(qi)(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)依(yi)照原(yuan)(yuan)(yuan)理(li)與不同槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的機(ji)械設計方式有(you)分(fen)為(wei)四種五類：第(di)一種是依(yi)賴活(huo)塞(sai)原(yuan)(yuan)(yuan)理(li)進行(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)運(yun)作(zuo)(zuo)(zuo)的方式，亦即(ji)透過導(dao)(dao)流(liu)使氣(qi)(qi)體(ti)(ti)推動(dong)(dong)(dong)活(huo)塞(sai)，活(huo)塞(sai)連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透過這一串的程(cheng)序完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。然而活(huo)塞(sai)的運(yun)作(zuo)(zuo)(zuo)以行(xing)(xing)程(cheng)為(wei)主，以行(xing)(xing)程(cheng)移動(dong)(dong)(dong)距離的長短劃分(fen)，而非以活(huo)塞(sai)的重量或者大小劃分(fen)。第(di)二(er)種是利用(yong)“收集”子(zi)彈的高壓氣(qi)(qi)之后(hou)再導(dao)(dao)流(liu)進入(ru)汽缸推動(dong)(dong)(dong)活(huo)塞(sai)或整個槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進行(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。第(di)三種是利用(yong)第(di)二(er)種“收集”氣(qi)(qi)體(ti)(ti)的原(yuan)(yuan)(yuan)理(li)進行(xing)(xing)推動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。后(hou)一種是經由氣(qi)(qi)導(dao)(dao)管導(dao)(dao)流(liu)氣(qi)(qi)體(ti)(ti)向后(hou)“吹送”槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。因此我們大約(yue)可以分(fen)為(wei)：短行(xing)(xing)程(cheng)活(huo)塞(sai)傳動(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程(cheng)活(huo)塞(sai)傳動(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)井集氣(qi)(qi)操(cao)作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直噴式氣(qi)(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
