氣(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)操(cao)(cao)作依照原(yuan)理與(yu)不同槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)機械設計方式有分(fen)為四種五類：第(di)一種是依賴(lai)活塞(sai)(sai)(sai)原(yuan)理進行槍(qiang)(qiang)(qiang)(qiang)機運(yun)(yun)(yun)作的(de)(de)方式，亦即(ji)透過(guo)(guo)導流(liu)使氣(qi)(qi)(qi)(qi)體推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)，活塞(sai)(sai)(sai)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機，透過(guo)(guo)這一串的(de)(de)程(cheng)序完成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作。然而(er)活塞(sai)(sai)(sai)的(de)(de)運(yun)(yun)(yun)作以(yi)行程(cheng)為主，以(yi)行程(cheng)移動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)距離的(de)(de)長短(duan)劃分(fen)，而(er)非以(yi)活塞(sai)(sai)(sai)的(de)(de)重量或(huo)者大小劃分(fen)。第(di)二種是利(li)用“收集”子彈的(de)(de)高壓氣(qi)(qi)(qi)(qi)之后(hou)再導流(liu)進入(ru)汽缸推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)或(huo)整個槍(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)機進行完成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作。第(di)三種是利(li)用第(di)二種“收集”氣(qi)(qi)(qi)(qi)體的(de)(de)原(yuan)理進行推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機完成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作。后(hou)一種是經由氣(qi)(qi)(qi)(qi)導管(guan)導流(liu)氣(qi)(qi)(qi)(qi)體向后(hou)“吹送”槍(qiang)(qiang)(qiang)(qiang)機完成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作。因此我們大約可(ke)以(yi)分(fen)為：短(duan)行程(cheng)活塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長行程(cheng)活塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)(qi)(qi)井集氣(qi)(qi)(qi)(qi)操(cao)(cao)作（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)口(kou)增壓器（Muzzle booster）。直噴式氣(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)操(cao)(cao)作（Direct impingement；也稱為Direct Gas Action）。
