氣(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)依照原理與不同槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)機(ji)械設計方(fang)式(shi)有(you)分(fen)為四種(zhong)(zhong)五類：第一(yi)種(zhong)(zhong)是(shi)依賴(lai)活(huo)(huo)塞原理進行(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)運(yun)作(zuo)(zuo)(zuo)的(de)(de)方(fang)式(shi)，亦即透過導流使(shi)氣(qi)體推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活(huo)(huo)塞，活(huo)(huo)塞連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透過這一(yi)串的(de)(de)程(cheng)(cheng)序完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。然而活(huo)(huo)塞的(de)(de)運(yun)作(zuo)(zuo)(zuo)以(yi)(yi)(yi)行(xing)(xing)程(cheng)(cheng)為主，以(yi)(yi)(yi)行(xing)(xing)程(cheng)(cheng)移動(dong)(dong)(dong)(dong)(dong)(dong)(dong)距離的(de)(de)長(chang)短(duan)劃(hua)分(fen)，而非以(yi)(yi)(yi)活(huo)(huo)塞的(de)(de)重量(liang)或者大(da)小劃(hua)分(fen)。第二種(zhong)(zhong)是(shi)利用(yong)“收(shou)集”子彈(dan)的(de)(de)高壓氣(qi)之后再導流進入汽缸推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活(huo)(huo)塞或整個(ge)槍(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進行(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。第三(san)種(zhong)(zhong)是(shi)利用(yong)第二種(zhong)(zhong)“收(shou)集”氣(qi)體的(de)(de)原理進行(xing)(xing)推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。后一(yi)種(zhong)(zhong)是(shi)經由氣(qi)導管導流氣(qi)體向后“吹送”槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。因此我們大(da)約可以(yi)(yi)(yi)分(fen)為：短(duan)行(xing)(xing)程(cheng)(cheng)活(huo)(huo)塞傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)行(xing)(xing)程(cheng)(cheng)活(huo)(huo)塞傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井集氣(qi)操作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直(zhi)噴式(shi)氣(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
