氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)依照原(yuan)理與(yu)不同(tong)槍(qiang)(qiang)枝的(de)(de)機(ji)械設計方式(shi)(shi)(shi)有分(fen)為(wei)四種(zhong)(zhong)(zhong)五類：第(di)一(yi)種(zhong)(zhong)(zhong)是(shi)依賴活(huo)(huo)塞原(yuan)理進行(xing)槍(qiang)(qiang)機(ji)運(yun)作(zuo)(zuo)的(de)(de)方式(shi)(shi)(shi)，亦即透(tou)過(guo)導流使氣(qi)體(ti)推(tui)動(dong)(dong)(dong)活(huo)(huo)塞，活(huo)(huo)塞連動(dong)(dong)(dong)槍(qiang)(qiang)機(ji)，透(tou)過(guo)這一(yi)串的(de)(de)程(cheng)序完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)運(yun)作(zuo)(zuo)。然而活(huo)(huo)塞的(de)(de)運(yun)作(zuo)(zuo)以(yi)行(xing)程(cheng)為(wei)主，以(yi)行(xing)程(cheng)移(yi)動(dong)(dong)(dong)距離的(de)(de)長短(duan)劃分(fen)，而非以(yi)活(huo)(huo)塞的(de)(de)重量或者大小劃分(fen)。第(di)二種(zhong)(zhong)(zhong)是(shi)利(li)(li)用“收集(ji)”子彈的(de)(de)高壓氣(qi)之(zhi)后再導流進入汽缸推(tui)動(dong)(dong)(dong)活(huo)(huo)塞或整個槍(qiang)(qiang)管連動(dong)(dong)(dong)到槍(qiang)(qiang)機(ji)進行(xing)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)運(yun)作(zuo)(zuo)。第(di)三(san)種(zhong)(zhong)(zhong)是(shi)利(li)(li)用第(di)二種(zhong)(zhong)(zhong)“收集(ji)”氣(qi)體(ti)的(de)(de)原(yuan)理進行(xing)推(tui)動(dong)(dong)(dong)槍(qiang)(qiang)管連動(dong)(dong)(dong)槍(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)運(yun)作(zuo)(zuo)。后一(yi)種(zhong)(zhong)(zhong)是(shi)經由氣(qi)導管導流氣(qi)體(ti)向后“吹送”槍(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)運(yun)作(zuo)(zuo)。因此我們大約可以(yi)分(fen)為(wei)：短(duan)行(xing)程(cheng)活(huo)(huo)塞傳(chuan)動(dong)(dong)(dong)式(shi)(shi)(shi)（Short stroke）。長行(xing)程(cheng)活(huo)(huo)塞傳(chuan)動(dong)(dong)(dong)式(shi)(shi)(shi)（Long stroke）。氣(qi)井(jing)集(ji)氣(qi)操(cao)作(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)口增壓器(qi)（Muzzle booster）。直噴(pen)式(shi)(shi)(shi)氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
