氣(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)依(yi)照原(yuan)(yuan)理(li)與不同槍枝的(de)(de)(de)機(ji)械設計方式有分為四種(zhong)五類：第一種(zhong)是依(yi)賴活塞(sai)(sai)(sai)(sai)原(yuan)(yuan)理(li)進行(xing)(xing)槍機(ji)運(yun)作(zuo)(zuo)的(de)(de)(de)方式，亦即透過(guo)(guo)導流(liu)使氣(qi)體(ti)(ti)推(tui)(tui)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)(sai)，活塞(sai)(sai)(sai)(sai)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍機(ji)，透過(guo)(guo)這一串的(de)(de)(de)程序完成(cheng)槍枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。然(ran)而活塞(sai)(sai)(sai)(sai)的(de)(de)(de)運(yun)作(zuo)(zuo)以(yi)行(xing)(xing)程為主，以(yi)行(xing)(xing)程移動(dong)(dong)(dong)(dong)(dong)(dong)(dong)距離的(de)(de)(de)長短劃(hua)分，而非以(yi)活塞(sai)(sai)(sai)(sai)的(de)(de)(de)重量或(huo)者大小(xiao)劃(hua)分。第二(er)種(zhong)是利用“收(shou)集”子彈的(de)(de)(de)高壓氣(qi)之(zhi)后(hou)再導流(liu)進入(ru)汽缸推(tui)(tui)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)(sai)或(huo)整個槍管連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)到(dao)槍機(ji)進行(xing)(xing)完成(cheng)槍枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。第三種(zhong)是利用第二(er)種(zhong)“收(shou)集”氣(qi)體(ti)(ti)的(de)(de)(de)原(yuan)(yuan)理(li)進行(xing)(xing)推(tui)(tui)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍管連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍機(ji)完成(cheng)槍枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。后(hou)一種(zhong)是經由氣(qi)導管導流(liu)氣(qi)體(ti)(ti)向后(hou)“吹送”槍機(ji)完成(cheng)槍枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。因此我們大約(yue)可以(yi)分為：短行(xing)(xing)程活塞(sai)(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程活塞(sai)(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)井集氣(qi)操作(zuo)(zuo)（Gas trap）。槍口(kou)增壓器（Muzzle booster）。直(zhi)噴式氣(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
