氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)依照原(yuan)(yuan)理與(yu)不同槍枝(zhi)(zhi)的(de)(de)機(ji)(ji)(ji)(ji)械設計方(fang)式有分為(wei)(wei)四(si)種五(wu)類：第(di)一種是(shi)依賴活塞原(yuan)(yuan)理進行(xing)(xing)槍機(ji)(ji)(ji)(ji)運作(zuo)的(de)(de)方(fang)式，亦即透過導流(liu)使氣(qi)(qi)(qi)體(ti)推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞，活塞連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍機(ji)(ji)(ji)(ji)，透過這一串的(de)(de)程(cheng)(cheng)序完(wan)成槍枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運作(zuo)。然而活塞的(de)(de)運作(zuo)以行(xing)(xing)程(cheng)(cheng)為(wei)(wei)主，以行(xing)(xing)程(cheng)(cheng)移動(dong)(dong)(dong)(dong)(dong)(dong)(dong)距離的(de)(de)長短(duan)劃分，而非以活塞的(de)(de)重(zhong)量或者大小(xiao)劃分。第(di)二種是(shi)利用“收集”子彈的(de)(de)高壓氣(qi)(qi)(qi)之后(hou)再導流(liu)進入(ru)汽缸推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞或整個槍管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)到槍機(ji)(ji)(ji)(ji)進行(xing)(xing)完(wan)成槍枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運作(zuo)。第(di)三種是(shi)利用第(di)二種“收集”氣(qi)(qi)(qi)體(ti)的(de)(de)原(yuan)(yuan)理進行(xing)(xing)推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍機(ji)(ji)(ji)(ji)完(wan)成槍枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運作(zuo)。后(hou)一種是(shi)經由氣(qi)(qi)(qi)導管(guan)導流(liu)氣(qi)(qi)(qi)體(ti)向(xiang)后(hou)“吹送”槍機(ji)(ji)(ji)(ji)完(wan)成槍枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運作(zuo)。因此我(wo)們大約可以分為(wei)(wei)：短(duan)行(xing)(xing)程(cheng)(cheng)活塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程(cheng)(cheng)活塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)(qi)井(jing)集氣(qi)(qi)(qi)操(cao)作(zuo)（Gas trap）。槍口(kou)增壓器（Muzzle booster）。直(zhi)噴式氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)（Direct impingement；也稱為(wei)(wei)Direct Gas Action）。
