氣(qi)(qi)動(dong)(dong)(dong)(dong)操作依(yi)照原(yuan)(yuan)理與(yu)不同槍枝(zhi)(zhi)的(de)(de)(de)機(ji)(ji)(ji)械設計(ji)方式有(you)分為四種(zhong)五類：第(di)一種(zhong)是依(yi)賴活塞(sai)(sai)原(yuan)(yuan)理進(jin)行(xing)槍機(ji)(ji)(ji)運作的(de)(de)(de)方式，亦即透過導(dao)流(liu)使氣(qi)(qi)體(ti)(ti)推動(dong)(dong)(dong)(dong)活塞(sai)(sai)，活塞(sai)(sai)連動(dong)(dong)(dong)(dong)槍機(ji)(ji)(ji)，透過這(zhe)一串的(de)(de)(de)程序完(wan)成(cheng)槍枝(zhi)(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運作。然而(er)活塞(sai)(sai)的(de)(de)(de)運作以行(xing)程為主，以行(xing)程移動(dong)(dong)(dong)(dong)距離的(de)(de)(de)長(chang)短劃分，而(er)非以活塞(sai)(sai)的(de)(de)(de)重量或者大小劃分。第(di)二種(zhong)是利用“收集”子彈的(de)(de)(de)高壓(ya)(ya)氣(qi)(qi)之后(hou)(hou)再(zai)導(dao)流(liu)進(jin)入汽缸推動(dong)(dong)(dong)(dong)活塞(sai)(sai)或整(zheng)個槍管(guan)連動(dong)(dong)(dong)(dong)到(dao)槍機(ji)(ji)(ji)進(jin)行(xing)完(wan)成(cheng)槍枝(zhi)(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運作。第(di)三種(zhong)是利用第(di)二種(zhong)“收集”氣(qi)(qi)體(ti)(ti)的(de)(de)(de)原(yuan)(yuan)理進(jin)行(xing)推動(dong)(dong)(dong)(dong)槍管(guan)連動(dong)(dong)(dong)(dong)槍機(ji)(ji)(ji)完(wan)成(cheng)槍枝(zhi)(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運作。后(hou)(hou)一種(zhong)是經(jing)由氣(qi)(qi)導(dao)管(guan)導(dao)流(liu)氣(qi)(qi)體(ti)(ti)向后(hou)(hou)“吹送”槍機(ji)(ji)(ji)完(wan)成(cheng)槍枝(zhi)(zhi)的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)運作。因此我們(men)大約(yue)可以分為：短行(xing)程活塞(sai)(sai)傳動(dong)(dong)(dong)(dong)式（Short stroke）。長(chang)行(xing)程活塞(sai)(sai)傳動(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)井集氣(qi)(qi)操作（Gas trap）。槍口增壓(ya)(ya)器（Muzzle booster）。直噴(pen)式氣(qi)(qi)動(dong)(dong)(dong)(dong)操作（Direct impingement；也稱為Direct Gas Action）。
