氣(qi)(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)依(yi)照原理(li)與不(bu)同槍(qiang)(qiang)枝的(de)(de)(de)機(ji)械(xie)設(she)計方式(shi)(shi)有分(fen)為四種(zhong)五類：第一(yi)種(zhong)是(shi)依(yi)賴活塞(sai)原理(li)進(jin)行槍(qiang)(qiang)機(ji)運作(zuo)的(de)(de)(de)方式(shi)(shi)，亦(yi)即透過導流使氣(qi)(qi)(qi)(qi)(qi)體(ti)推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)，活塞(sai)連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)，透過這一(yi)串的(de)(de)(de)程(cheng)序完(wan)成槍(qiang)(qiang)枝的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運作(zuo)。然而活塞(sai)的(de)(de)(de)運作(zuo)以(yi)(yi)行程(cheng)為主，以(yi)(yi)行程(cheng)移(yi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)距離的(de)(de)(de)長短劃分(fen)，而非以(yi)(yi)活塞(sai)的(de)(de)(de)重量或(huo)者大小劃分(fen)。第二(er)種(zhong)是(shi)利用“收集”子(zi)彈的(de)(de)(de)高壓(ya)氣(qi)(qi)(qi)(qi)(qi)之后再導流進(jin)入汽(qi)缸推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)或(huo)整個(ge)槍(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)到(dao)槍(qiang)(qiang)機(ji)進(jin)行完(wan)成槍(qiang)(qiang)枝的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運作(zuo)。第三種(zhong)是(shi)利用第二(er)種(zhong)“收集”氣(qi)(qi)(qi)(qi)(qi)體(ti)的(de)(de)(de)原理(li)進(jin)行推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)枝的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運作(zuo)。后一(yi)種(zhong)是(shi)經(jing)由(you)氣(qi)(qi)(qi)(qi)(qi)導管(guan)導流氣(qi)(qi)(qi)(qi)(qi)體(ti)向后“吹(chui)送”槍(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)枝的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運作(zuo)。因此我們大約可以(yi)(yi)分(fen)為：短行程(cheng)活塞(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長行程(cheng)活塞(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)(qi)(qi)(qi)(qi)井集氣(qi)(qi)(qi)(qi)(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)口(kou)增壓(ya)器（Muzzle booster）。直噴式(shi)(shi)氣(qi)(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)（Direct impingement；也稱為Direct Gas Action）。
