氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)依(yi)照(zhao)原(yuan)理(li)與不(bu)同槍(qiang)(qiang)枝(zhi)的(de)機(ji)械設計(ji)方(fang)式(shi)有分(fen)(fen)為四(si)種(zhong)五類(lei)：第一種(zhong)是(shi)依(yi)賴活塞(sai)原(yuan)理(li)進(jin)(jin)行(xing)(xing)槍(qiang)(qiang)機(ji)運(yun)(yun)(yun)作(zuo)(zuo)(zuo)的(de)方(fang)式(shi)，亦即透(tou)過導(dao)流使氣(qi)體(ti)推動(dong)(dong)(dong)(dong)(dong)活塞(sai)，活塞(sai)連(lian)(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)，透(tou)過這一串的(de)程(cheng)序完(wan)成(cheng)槍(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)(zuo)(zuo)。然而活塞(sai)的(de)運(yun)(yun)(yun)作(zuo)(zuo)(zuo)以行(xing)(xing)程(cheng)為主，以行(xing)(xing)程(cheng)移動(dong)(dong)(dong)(dong)(dong)距離的(de)長短(duan)劃分(fen)(fen)，而非以活塞(sai)的(de)重量或者大小劃分(fen)(fen)。第二種(zhong)是(shi)利用“收集(ji)”子彈的(de)高壓(ya)氣(qi)之(zhi)后再導(dao)流進(jin)(jin)入汽(qi)缸推動(dong)(dong)(dong)(dong)(dong)活塞(sai)或整個槍(qiang)(qiang)管(guan)連(lian)(lian)動(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)機(ji)進(jin)(jin)行(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)(zuo)(zuo)。第三種(zhong)是(shi)利用第二種(zhong)“收集(ji)”氣(qi)體(ti)的(de)原(yuan)理(li)進(jin)(jin)行(xing)(xing)推動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)管(guan)連(lian)(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)(zuo)(zuo)。后一種(zhong)是(shi)經由氣(qi)導(dao)管(guan)導(dao)流氣(qi)體(ti)向后“吹送”槍(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)枝(zhi)的(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)(zuo)(zuo)。因此我們大約可以分(fen)(fen)為：短(duan)行(xing)(xing)程(cheng)活塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)(xing)程(cheng)活塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井(jing)集(ji)氣(qi)操作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)口(kou)增壓(ya)器（Muzzle booster）。直噴式(shi)氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)（Direct impingement；也稱(cheng)為Direct Gas Action）。
