氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)(zuo)依照原(yuan)理(li)與(yu)不同(tong)槍(qiang)枝(zhi)的(de)(de)(de)機(ji)(ji)械設(she)計方(fang)式(shi)(shi)有分(fen)(fen)(fen)為四種(zhong)五類：第(di)一(yi)種(zhong)是依賴活(huo)(huo)塞(sai)原(yuan)理(li)進行(xing)槍(qiang)機(ji)(ji)運(yun)作(zuo)(zuo)(zuo)(zuo)的(de)(de)(de)方(fang)式(shi)(shi)，亦即透過導(dao)流使氣(qi)體推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)，活(huo)(huo)塞(sai)連(lian)(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)機(ji)(ji)，透過這一(yi)串的(de)(de)(de)程序完(wan)成槍(qiang)枝(zhi)的(de)(de)(de)自動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)(zuo)。然而活(huo)(huo)塞(sai)的(de)(de)(de)運(yun)作(zuo)(zuo)(zuo)(zuo)以(yi)行(xing)程為主，以(yi)行(xing)程移動(dong)(dong)(dong)(dong)(dong)距離的(de)(de)(de)長短(duan)劃(hua)分(fen)(fen)(fen)，而非以(yi)活(huo)(huo)塞(sai)的(de)(de)(de)重量或(huo)者大(da)小劃(hua)分(fen)(fen)(fen)。第(di)二種(zhong)是利(li)用“收集”子彈(dan)的(de)(de)(de)高壓氣(qi)之后再導(dao)流進入汽缸推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)或(huo)整個槍(qiang)管連(lian)(lian)動(dong)(dong)(dong)(dong)(dong)到槍(qiang)機(ji)(ji)進行(xing)完(wan)成槍(qiang)枝(zhi)的(de)(de)(de)自動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)(zuo)。第(di)三(san)種(zhong)是利(li)用第(di)二種(zhong)“收集”氣(qi)體的(de)(de)(de)原(yuan)理(li)進行(xing)推(tui)動(dong)(dong)(dong)(dong)(dong)槍(qiang)管連(lian)(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)機(ji)(ji)完(wan)成槍(qiang)枝(zhi)的(de)(de)(de)自動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)(zuo)。后一(yi)種(zhong)是經由氣(qi)導(dao)管導(dao)流氣(qi)體向(xiang)后“吹送”槍(qiang)機(ji)(ji)完(wan)成槍(qiang)枝(zhi)的(de)(de)(de)自動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)自動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)(zuo)。因(yin)此我們大(da)約可以(yi)分(fen)(fen)(fen)為：短(duan)行(xing)程活(huo)(huo)塞(sai)傳動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長行(xing)程活(huo)(huo)塞(sai)傳動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)井集氣(qi)操作(zuo)(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)口(kou)增壓器（Muzzle booster）。直噴(pen)式(shi)(shi)氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)(zuo)（Direct impingement；也稱(cheng)為Direct Gas Action）。
