氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)依(yi)照(zhao)原(yuan)(yuan)(yuan)理(li)與(yu)不同槍(qiang)(qiang)枝(zhi)的(de)(de)(de)機(ji)械設計方式(shi)(shi)有分為四種(zhong)(zhong)五(wu)類：第(di)一種(zhong)(zhong)是依(yi)賴(lai)活(huo)(huo)塞(sai)原(yuan)(yuan)(yuan)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(tou)過(guo)導(dao)(dao)流使氣(qi)(qi)(qi)體推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)，活(huo)(huo)塞(sai)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)，透(tou)過(guo)這一串的(de)(de)(de)程(cheng)序(xu)完成(cheng)槍(qiang)(qiang)枝(zhi)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(ran)而活(huo)(huo)塞(sai)的(de)(de)(de)運作(zuo)以行程(cheng)為主(zhu)，以行程(cheng)移(yi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)距離(li)的(de)(de)(de)長(chang)短劃分，而非以活(huo)(huo)塞(sai)的(de)(de)(de)重量(liang)或者大小劃分。第(di)二(er)種(zhong)(zhong)是利(li)用(yong)“收(shou)集(ji)”子彈的(de)(de)(de)高壓(ya)氣(qi)(qi)(qi)之后再(zai)導(dao)(dao)流進(jin)入(ru)汽缸推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)或整個槍(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)機(ji)進(jin)行完成(cheng)槍(qiang)(qiang)枝(zhi)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(di)三種(zhong)(zhong)是利(li)用(yong)第(di)二(er)種(zhong)(zhong)“收(shou)集(ji)”氣(qi)(qi)(qi)體的(de)(de)(de)原(yuan)(yuan)(yuan)理(li)進(jin)行推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)完成(cheng)槍(qiang)(qiang)枝(zhi)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)。后一種(zhong)(zhong)是經由(you)氣(qi)(qi)(qi)導(dao)(dao)管(guan)導(dao)(dao)流氣(qi)(qi)(qi)體向(xiang)后“吹送”槍(qiang)(qiang)機(ji)完成(cheng)槍(qiang)(qiang)枝(zhi)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(ci)我們大約可以分為：短行程(cheng)活(huo)(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長(chang)行程(cheng)活(huo)(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)(qi)(qi)井(jing)集(ji)氣(qi)(qi)(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)口增(zeng)壓(ya)器（Muzzle booster）。直噴式(shi)(shi)氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)（Direct impingement；也稱為Direct Gas Action）。
