氣(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)依(yi)照原(yuan)理(li)與不同槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)(de)(de)機(ji)械設計方式(shi)有分為四種(zhong)五類(lei)：第一種(zhong)是依(yi)賴(lai)活(huo)(huo)(huo)塞(sai)(sai)(sai)原(yuan)理(li)進行(xing)槍(qiang)(qiang)(qiang)機(ji)運作(zuo)的(de)(de)(de)(de)(de)(de)方式(shi)，亦即透過(guo)導(dao)(dao)流使氣(qi)體推動(dong)(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)(sai)(sai)，活(huo)(huo)(huo)塞(sai)(sai)(sai)連動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透過(guo)這一串的(de)(de)(de)(de)(de)(de)程(cheng)(cheng)序(xu)完成槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)。然而活(huo)(huo)(huo)塞(sai)(sai)(sai)的(de)(de)(de)(de)(de)(de)運作(zuo)以(yi)行(xing)程(cheng)(cheng)為主，以(yi)行(xing)程(cheng)(cheng)移動(dong)(dong)(dong)(dong)距(ju)離的(de)(de)(de)(de)(de)(de)長(chang)短劃(hua)分，而非以(yi)活(huo)(huo)(huo)塞(sai)(sai)(sai)的(de)(de)(de)(de)(de)(de)重量(liang)或者大小(xiao)劃(hua)分。第二種(zhong)是利(li)用“收(shou)集(ji)”子彈的(de)(de)(de)(de)(de)(de)高壓氣(qi)之(zhi)后(hou)再導(dao)(dao)流進入(ru)汽缸(gang)推動(dong)(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)(sai)(sai)或整個槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進行(xing)完成槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)。第三種(zhong)是利(li)用第二種(zhong)“收(shou)集(ji)”氣(qi)體的(de)(de)(de)(de)(de)(de)原(yuan)理(li)進行(xing)推動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完成槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)。后(hou)一種(zhong)是經(jing)由氣(qi)導(dao)(dao)管導(dao)(dao)流氣(qi)體向后(hou)“吹送”槍(qiang)(qiang)(qiang)機(ji)完成槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)。因此我們(men)大約可以(yi)分為：短行(xing)程(cheng)(cheng)活(huo)(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)行(xing)程(cheng)(cheng)活(huo)(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井(jing)集(ji)氣(qi)操(cao)作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口(kou)增壓器（Muzzle booster）。直噴式(shi)氣(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)（Direct impingement；也稱為Direct Gas Action）。
