氣(qi)動(dong)(dong)(dong)操(cao)(cao)作依照原理(li)與不(bu)同(tong)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)機(ji)械(xie)設計方式(shi)有分(fen)為(wei)四種(zhong)(zhong)五(wu)類：第(di)(di)一種(zhong)(zhong)是依賴(lai)活(huo)(huo)(huo)塞(sai)原理(li)進(jin)行(xing)槍(qiang)(qiang)(qiang)機(ji)運(yun)作的(de)(de)方式(shi)，亦即透(tou)過導流使氣(qi)體(ti)推動(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)，活(huo)(huo)(huo)塞(sai)連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透(tou)過這一串(chuan)的(de)(de)程(cheng)序完成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)運(yun)作。然而活(huo)(huo)(huo)塞(sai)的(de)(de)運(yun)作以行(xing)程(cheng)為(wei)主，以行(xing)程(cheng)移動(dong)(dong)(dong)距離(li)的(de)(de)長(chang)短劃分(fen)，而非以活(huo)(huo)(huo)塞(sai)的(de)(de)重量或(huo)者大(da)(da)小劃分(fen)。第(di)(di)二(er)種(zhong)(zhong)是利用(yong)“收(shou)集(ji)”子彈的(de)(de)高壓(ya)氣(qi)之后再導流進(jin)入汽(qi)缸推動(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)或(huo)整(zheng)個槍(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進(jin)行(xing)完成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)運(yun)作。第(di)(di)三(san)種(zhong)(zhong)是利用(yong)第(di)(di)二(er)種(zhong)(zhong)“收(shou)集(ji)”氣(qi)體(ti)的(de)(de)原理(li)進(jin)行(xing)推動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)運(yun)作。后一種(zhong)(zhong)是經由氣(qi)導管(guan)導流氣(qi)體(ti)向后“吹送”槍(qiang)(qiang)(qiang)機(ji)完成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)運(yun)作。因此(ci)我們大(da)(da)約(yue)可以分(fen)為(wei)：短行(xing)程(cheng)活(huo)(huo)(huo)塞(sai)傳動(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)行(xing)程(cheng)活(huo)(huo)(huo)塞(sai)傳動(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井集(ji)氣(qi)操(cao)(cao)作（Gas trap）。槍(qiang)(qiang)(qiang)口增壓(ya)器（Muzzle booster）。直(zhi)噴式(shi)氣(qi)動(dong)(dong)(dong)操(cao)(cao)作（Direct impingement；也稱(cheng)為(wei)Direct Gas Action）。
