氣(qi)(qi)動(dong)(dong)操(cao)(cao)作(zuo)依(yi)(yi)照原(yuan)(yuan)理(li)與(yu)不同槍枝(zhi)的(de)(de)機械設計方式有分為(wei)四種(zhong)(zhong)(zhong)五類：第一(yi)(yi)種(zhong)(zhong)(zhong)是(shi)(shi)依(yi)(yi)賴活(huo)塞(sai)(sai)(sai)原(yuan)(yuan)理(li)進行(xing)(xing)(xing)槍機運(yun)(yun)作(zuo)的(de)(de)方式，亦即透(tou)過導(dao)(dao)流使氣(qi)(qi)體推動(dong)(dong)活(huo)塞(sai)(sai)(sai)，活(huo)塞(sai)(sai)(sai)連動(dong)(dong)槍機，透(tou)過這一(yi)(yi)串(chuan)的(de)(de)程序完(wan)(wan)成槍枝(zhi)的(de)(de)自動(dong)(dong)/半自動(dong)(dong)運(yun)(yun)作(zuo)。然而活(huo)塞(sai)(sai)(sai)的(de)(de)運(yun)(yun)作(zuo)以行(xing)(xing)(xing)程為(wei)主，以行(xing)(xing)(xing)程移(yi)動(dong)(dong)距離的(de)(de)長短(duan)劃(hua)分，而非(fei)以活(huo)塞(sai)(sai)(sai)的(de)(de)重(zhong)量或者大小劃(hua)分。第二種(zhong)(zhong)(zhong)是(shi)(shi)利用“收集”子彈的(de)(de)高壓(ya)氣(qi)(qi)之(zhi)后(hou)再導(dao)(dao)流進入汽缸(gang)推動(dong)(dong)活(huo)塞(sai)(sai)(sai)或整個(ge)槍管(guan)連動(dong)(dong)到槍機進行(xing)(xing)(xing)完(wan)(wan)成槍枝(zhi)的(de)(de)自動(dong)(dong)/半自動(dong)(dong)運(yun)(yun)作(zuo)。第三(san)種(zhong)(zhong)(zhong)是(shi)(shi)利用第二種(zhong)(zhong)(zhong)“收集”氣(qi)(qi)體的(de)(de)原(yuan)(yuan)理(li)進行(xing)(xing)(xing)推動(dong)(dong)槍管(guan)連動(dong)(dong)槍機完(wan)(wan)成槍枝(zhi)的(de)(de)自動(dong)(dong)/半自動(dong)(dong)運(yun)(yun)作(zuo)。后(hou)一(yi)(yi)種(zhong)(zhong)(zhong)是(shi)(shi)經由氣(qi)(qi)導(dao)(dao)管(guan)導(dao)(dao)流氣(qi)(qi)體向后(hou)“吹送”槍機完(wan)(wan)成槍枝(zhi)的(de)(de)自動(dong)(dong)/半自動(dong)(dong)運(yun)(yun)作(zuo)。因(yin)此(ci)我們大約可(ke)以分為(wei)：短(duan)行(xing)(xing)(xing)程活(huo)塞(sai)(sai)(sai)傳動(dong)(dong)式（Short stroke）。長行(xing)(xing)(xing)程活(huo)塞(sai)(sai)(sai)傳動(dong)(dong)式（Long stroke）。氣(qi)(qi)井集氣(qi)(qi)操(cao)(cao)作(zuo)（Gas trap）。槍口(kou)增壓(ya)器（Muzzle booster）。直噴式氣(qi)(qi)動(dong)(dong)操(cao)(cao)作(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
