氣(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)依(yi)照原理與不同槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)機(ji)(ji)械設計方式(shi)有分為四種(zhong)五(wu)類：第一種(zhong)是依(yi)賴活(huo)塞(sai)(sai)(sai)原理進(jin)行(xing)槍(qiang)(qiang)(qiang)機(ji)(ji)運作(zuo)(zuo)的(de)(de)(de)方式(shi)，亦即透(tou)過導流(liu)使氣(qi)體(ti)推(tui)動(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)，活(huo)塞(sai)(sai)(sai)連(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)，透(tou)過這一串的(de)(de)(de)程(cheng)(cheng)序完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)。然而活(huo)塞(sai)(sai)(sai)的(de)(de)(de)運作(zuo)(zuo)以行(xing)程(cheng)(cheng)為主，以行(xing)程(cheng)(cheng)移動(dong)(dong)(dong)(dong)距離的(de)(de)(de)長短(duan)劃(hua)分，而非以活(huo)塞(sai)(sai)(sai)的(de)(de)(de)重量(liang)或者(zhe)大(da)小(xiao)劃(hua)分。第二種(zhong)是利用(yong)“收(shou)集(ji)”子彈的(de)(de)(de)高壓氣(qi)之后再導流(liu)進(jin)入汽缸推(tui)動(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)或整個槍(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)(dong)到(dao)槍(qiang)(qiang)(qiang)機(ji)(ji)進(jin)行(xing)完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)。第三種(zhong)是利用(yong)第二種(zhong)“收(shou)集(ji)”氣(qi)體(ti)的(de)(de)(de)原理進(jin)行(xing)推(tui)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)。后一種(zhong)是經由氣(qi)導管(guan)導流(liu)氣(qi)體(ti)向(xiang)后“吹送”槍(qiang)(qiang)(qiang)機(ji)(ji)完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)。因此我們大(da)約(yue)可以分為：短(duan)行(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)程(cheng)(cheng)活(huo)塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井集(ji)氣(qi)操(cao)作(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口增壓器(qi)（Muzzle booster）。直噴式(shi)氣(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
