氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)依照原(yuan)理與不同槍(qiang)(qiang)枝的(de)(de)(de)機(ji)械設計方式有分為(wei)四種(zhong)五類：第一種(zhong)是(shi)依賴(lai)活塞(sai)原(yuan)理進行(xing)槍(qiang)(qiang)機(ji)運(yun)(yun)作(zuo)(zuo)(zuo)的(de)(de)(de)方式，亦即透(tou)過(guo)導流使氣(qi)體推(tui)動(dong)(dong)(dong)活塞(sai)，活塞(sai)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)機(ji)，透(tou)過(guo)這一串的(de)(de)(de)程(cheng)序完(wan)成槍(qiang)(qiang)枝的(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。然而活塞(sai)的(de)(de)(de)運(yun)(yun)作(zuo)(zuo)(zuo)以(yi)行(xing)程(cheng)為(wei)主，以(yi)行(xing)程(cheng)移動(dong)(dong)(dong)距離(li)的(de)(de)(de)長短劃(hua)分，而非以(yi)活塞(sai)的(de)(de)(de)重量或者大小劃(hua)分。第二種(zhong)是(shi)利用(yong)“收(shou)集(ji)”子彈的(de)(de)(de)高壓氣(qi)之后再導流進入(ru)汽缸推(tui)動(dong)(dong)(dong)活塞(sai)或整個槍(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)到槍(qiang)(qiang)機(ji)進行(xing)完(wan)成槍(qiang)(qiang)枝的(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。第三種(zhong)是(shi)利用(yong)第二種(zhong)“收(shou)集(ji)”氣(qi)體的(de)(de)(de)原(yuan)理進行(xing)推(tui)動(dong)(dong)(dong)槍(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)枝的(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。后一種(zhong)是(shi)經由氣(qi)導管(guan)導流氣(qi)體向后“吹送(song)”槍(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)枝的(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。因此我(wo)們大約可以(yi)分為(wei)：短行(xing)程(cheng)活塞(sai)傳動(dong)(dong)(dong)式（Short stroke）。長行(xing)程(cheng)活塞(sai)傳動(dong)(dong)(dong)式（Long stroke）。氣(qi)井(jing)集(ji)氣(qi)操(cao)作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)口增壓器（Muzzle booster）。直噴(pen)式氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
