氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)(cao)(cao)作(zuo)(zuo)(zuo)依(yi)照原理(li)與(yu)不同槍(qiang)枝(zhi)的(de)(de)(de)機(ji)械設計(ji)方式(shi)(shi)有(you)分(fen)為四種(zhong)五類(lei)：第一(yi)種(zhong)是(shi)(shi)依(yi)賴活塞(sai)(sai)原理(li)進(jin)行(xing)槍(qiang)機(ji)運作(zuo)(zuo)(zuo)的(de)(de)(de)方式(shi)(shi)，亦即透(tou)過導(dao)流使氣(qi)(qi)(qi)體推動(dong)(dong)(dong)(dong)活塞(sai)(sai)，活塞(sai)(sai)連動(dong)(dong)(dong)(dong)槍(qiang)機(ji)，透(tou)過這一(yi)串的(de)(de)(de)程(cheng)序完成(cheng)(cheng)槍(qiang)枝(zhi)的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)(zuo)。然而活塞(sai)(sai)的(de)(de)(de)運作(zuo)(zuo)(zuo)以行(xing)程(cheng)為主，以行(xing)程(cheng)移動(dong)(dong)(dong)(dong)距離的(de)(de)(de)長短(duan)劃分(fen)，而非以活塞(sai)(sai)的(de)(de)(de)重量或者大(da)小劃分(fen)。第二種(zhong)是(shi)(shi)利用(yong)(yong)“收(shou)集(ji)(ji)”子彈(dan)的(de)(de)(de)高(gao)壓(ya)(ya)氣(qi)(qi)(qi)之后再導(dao)流進(jin)入汽缸推動(dong)(dong)(dong)(dong)活塞(sai)(sai)或整個槍(qiang)管(guan)(guan)連動(dong)(dong)(dong)(dong)到槍(qiang)機(ji)進(jin)行(xing)完成(cheng)(cheng)槍(qiang)枝(zhi)的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)(zuo)。第三種(zhong)是(shi)(shi)利用(yong)(yong)第二種(zhong)“收(shou)集(ji)(ji)”氣(qi)(qi)(qi)體的(de)(de)(de)原理(li)進(jin)行(xing)推動(dong)(dong)(dong)(dong)槍(qiang)管(guan)(guan)連動(dong)(dong)(dong)(dong)槍(qiang)機(ji)完成(cheng)(cheng)槍(qiang)枝(zhi)的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)(zuo)。后一(yi)種(zhong)是(shi)(shi)經(jing)由(you)氣(qi)(qi)(qi)導(dao)管(guan)(guan)導(dao)流氣(qi)(qi)(qi)體向后“吹送”槍(qiang)機(ji)完成(cheng)(cheng)槍(qiang)枝(zhi)的(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)(zuo)。因此我們大(da)約可以分(fen)為：短(duan)行(xing)程(cheng)活塞(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長行(xing)程(cheng)活塞(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)(qi)(qi)井集(ji)(ji)氣(qi)(qi)(qi)操(cao)(cao)(cao)作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)口增壓(ya)(ya)器（Muzzle booster）。直噴式(shi)(shi)氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)(cao)(cao)作(zuo)(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
