氣(qi)動(dong)(dong)(dong)操作(zuo)(zuo)依(yi)照原(yuan)理(li)與(yu)不同槍(qiang)枝(zhi)的(de)機(ji)械(xie)設(she)計方(fang)式有分為四(si)種(zhong)五類：第(di)(di)一種(zhong)是(shi)依(yi)賴活(huo)塞(sai)原(yuan)理(li)進(jin)行(xing)(xing)槍(qiang)機(ji)運(yun)作(zuo)(zuo)的(de)方(fang)式，亦即(ji)透過(guo)導(dao)(dao)流(liu)使(shi)氣(qi)體推(tui)動(dong)(dong)(dong)活(huo)塞(sai)，活(huo)塞(sai)連動(dong)(dong)(dong)槍(qiang)機(ji)，透過(guo)這(zhe)一串的(de)程(cheng)序完成(cheng)(cheng)槍(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)運(yun)作(zuo)(zuo)。然而活(huo)塞(sai)的(de)運(yun)作(zuo)(zuo)以(yi)(yi)行(xing)(xing)程(cheng)為主，以(yi)(yi)行(xing)(xing)程(cheng)移動(dong)(dong)(dong)距離的(de)長短(duan)(duan)劃(hua)分，而非以(yi)(yi)活(huo)塞(sai)的(de)重量或(huo)者大小劃(hua)分。第(di)(di)二(er)種(zhong)是(shi)利(li)用“收(shou)集”子彈的(de)高(gao)壓氣(qi)之后再導(dao)(dao)流(liu)進(jin)入(ru)汽缸(gang)推(tui)動(dong)(dong)(dong)活(huo)塞(sai)或(huo)整(zheng)個(ge)槍(qiang)管連動(dong)(dong)(dong)到(dao)槍(qiang)機(ji)進(jin)行(xing)(xing)完成(cheng)(cheng)槍(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)運(yun)作(zuo)(zuo)。第(di)(di)三種(zhong)是(shi)利(li)用第(di)(di)二(er)種(zhong)“收(shou)集”氣(qi)體的(de)原(yuan)理(li)進(jin)行(xing)(xing)推(tui)動(dong)(dong)(dong)槍(qiang)管連動(dong)(dong)(dong)槍(qiang)機(ji)完成(cheng)(cheng)槍(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)運(yun)作(zuo)(zuo)。后一種(zhong)是(shi)經由氣(qi)導(dao)(dao)管導(dao)(dao)流(liu)氣(qi)體向(xiang)后“吹送(song)”槍(qiang)機(ji)完成(cheng)(cheng)槍(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)運(yun)作(zuo)(zuo)。因此我們大約可以(yi)(yi)分為：短(duan)(duan)行(xing)(xing)程(cheng)活(huo)塞(sai)傳動(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程(cheng)活(huo)塞(sai)傳動(dong)(dong)(dong)式（Long stroke）。氣(qi)井集氣(qi)操作(zuo)(zuo)（Gas trap）。槍(qiang)口增壓器(qi)（Muzzle booster）。直噴式氣(qi)動(dong)(dong)(dong)操作(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
