氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)依(yi)照(zhao)原理(li)與不同槍(qiang)枝(zhi)(zhi)的(de)(de)機械設計方式有(you)分(fen)為(wei)四(si)種五類：第(di)(di)一(yi)種是依(yi)賴(lai)活(huo)(huo)塞(sai)原理(li)進行(xing)槍(qiang)機運作(zuo)的(de)(de)方式，亦(yi)即透(tou)過導流(liu)使氣(qi)(qi)(qi)體推(tui)動(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)，活(huo)(huo)塞(sai)連(lian)動(dong)(dong)(dong)(dong)槍(qiang)機，透(tou)過這(zhe)一(yi)串的(de)(de)程(cheng)序完(wan)成(cheng)(cheng)槍(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運作(zuo)。然而活(huo)(huo)塞(sai)的(de)(de)運作(zuo)以行(xing)程(cheng)為(wei)主，以行(xing)程(cheng)移動(dong)(dong)(dong)(dong)距離(li)的(de)(de)長短(duan)劃(hua)分(fen)，而非以活(huo)(huo)塞(sai)的(de)(de)重量或者(zhe)大小劃(hua)分(fen)。第(di)(di)二種是利用“收(shou)集(ji)”子彈的(de)(de)高壓氣(qi)(qi)(qi)之后(hou)(hou)再導流(liu)進入汽(qi)缸推(tui)動(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)或整個槍(qiang)管連(lian)動(dong)(dong)(dong)(dong)到(dao)槍(qiang)機進行(xing)完(wan)成(cheng)(cheng)槍(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運作(zuo)。第(di)(di)三種是利用第(di)(di)二種“收(shou)集(ji)”氣(qi)(qi)(qi)體的(de)(de)原理(li)進行(xing)推(tui)動(dong)(dong)(dong)(dong)槍(qiang)管連(lian)動(dong)(dong)(dong)(dong)槍(qiang)機完(wan)成(cheng)(cheng)槍(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運作(zuo)。后(hou)(hou)一(yi)種是經由氣(qi)(qi)(qi)導管導流(liu)氣(qi)(qi)(qi)體向(xiang)后(hou)(hou)“吹(chui)送”槍(qiang)機完(wan)成(cheng)(cheng)槍(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運作(zuo)。因此我們(men)大約(yue)可(ke)以分(fen)為(wei)：短(duan)行(xing)程(cheng)活(huo)(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)式（Short stroke）。長行(xing)程(cheng)活(huo)(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)(qi)井集(ji)氣(qi)(qi)(qi)操(cao)作(zuo)（Gas trap）。槍(qiang)口增壓器（Muzzle booster）。直噴式氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
