氣(qi)(qi)(qi)(qi)動(dong)(dong)操(cao)作(zuo)(zuo)依照原理(li)與不同槍(qiang)(qiang)枝的(de)(de)(de)機(ji)械設計方式(shi)(shi)有分為(wei)四種(zhong)(zhong)五類：第一(yi)(yi)種(zhong)(zhong)是(shi)依賴活(huo)塞(sai)(sai)原理(li)進(jin)(jin)行(xing)槍(qiang)(qiang)機(ji)運作(zuo)(zuo)的(de)(de)(de)方式(shi)(shi)，亦(yi)即透過(guo)(guo)導流使氣(qi)(qi)(qi)(qi)體推(tui)動(dong)(dong)活(huo)塞(sai)(sai)，活(huo)塞(sai)(sai)連(lian)(lian)動(dong)(dong)槍(qiang)(qiang)機(ji)，透過(guo)(guo)這一(yi)(yi)串的(de)(de)(de)程序完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)(de)自(zi)動(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)運作(zuo)(zuo)。然而(er)活(huo)塞(sai)(sai)的(de)(de)(de)運作(zuo)(zuo)以行(xing)程為(wei)主(zhu)，以行(xing)程移動(dong)(dong)距(ju)離的(de)(de)(de)長短(duan)劃分，而(er)非(fei)以活(huo)塞(sai)(sai)的(de)(de)(de)重量或者大小(xiao)劃分。第二種(zhong)(zhong)是(shi)利用“收(shou)集(ji)(ji)”子彈的(de)(de)(de)高壓氣(qi)(qi)(qi)(qi)之后(hou)再導流進(jin)(jin)入(ru)汽(qi)缸(gang)推(tui)動(dong)(dong)活(huo)塞(sai)(sai)或整個槍(qiang)(qiang)管(guan)連(lian)(lian)動(dong)(dong)到槍(qiang)(qiang)機(ji)進(jin)(jin)行(xing)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)(de)自(zi)動(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)運作(zuo)(zuo)。第三種(zhong)(zhong)是(shi)利用第二種(zhong)(zhong)“收(shou)集(ji)(ji)”氣(qi)(qi)(qi)(qi)體的(de)(de)(de)原理(li)進(jin)(jin)行(xing)推(tui)動(dong)(dong)槍(qiang)(qiang)管(guan)連(lian)(lian)動(dong)(dong)槍(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)(de)自(zi)動(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)運作(zuo)(zuo)。后(hou)一(yi)(yi)種(zhong)(zhong)是(shi)經由氣(qi)(qi)(qi)(qi)導管(guan)導流氣(qi)(qi)(qi)(qi)體向(xiang)后(hou)“吹送”槍(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)(de)自(zi)動(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)運作(zuo)(zuo)。因此我們大約(yue)可以分為(wei)：短(duan)行(xing)程活(huo)塞(sai)(sai)傳動(dong)(dong)式(shi)(shi)（Short stroke）。長行(xing)程活(huo)塞(sai)(sai)傳動(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)(qi)(qi)(qi)井集(ji)(ji)氣(qi)(qi)(qi)(qi)操(cao)作(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)口(kou)增壓器（Muzzle booster）。直(zhi)噴式(shi)(shi)氣(qi)(qi)(qi)(qi)動(dong)(dong)操(cao)作(zuo)(zuo)（Direct impingement；也稱(cheng)為(wei)Direct Gas Action）。
