氣動(dong)(dong)(dong)(dong)操(cao)作依(yi)(yi)照原理(li)(li)與(yu)不同槍(qiang)(qiang)(qiang)枝的(de)(de)機(ji)(ji)(ji)械設計方(fang)式(shi)有分(fen)為(wei)四(si)種五類：第(di)一種是依(yi)(yi)賴(lai)活(huo)(huo)(huo)塞(sai)原理(li)(li)進(jin)行(xing)(xing)(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)運作的(de)(de)方(fang)式(shi)，亦(yi)即透過(guo)導流使氣體(ti)推動(dong)(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)，活(huo)(huo)(huo)塞(sai)連(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)，透過(guo)這(zhe)一串(chuan)的(de)(de)程(cheng)序(xu)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)運作。然而(er)活(huo)(huo)(huo)塞(sai)的(de)(de)運作以(yi)行(xing)(xing)(xing)(xing)程(cheng)為(wei)主(zhu)，以(yi)行(xing)(xing)(xing)(xing)程(cheng)移(yi)動(dong)(dong)(dong)(dong)距離的(de)(de)長(chang)(chang)短(duan)劃(hua)分(fen)，而(er)非以(yi)活(huo)(huo)(huo)塞(sai)的(de)(de)重量或者大小劃(hua)分(fen)。第(di)二種是利用(yong)“收集(ji)(ji)”子(zi)彈(dan)的(de)(de)高壓氣之后(hou)再導流進(jin)入汽缸(gang)推動(dong)(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)或整個槍(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)進(jin)行(xing)(xing)(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)運作。第(di)三種是利用(yong)第(di)二種“收集(ji)(ji)”氣體(ti)的(de)(de)原理(li)(li)進(jin)行(xing)(xing)(xing)(xing)推動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)運作。后(hou)一種是經由氣導管導流氣體(ti)向后(hou)“吹送”槍(qiang)(qiang)(qiang)機(ji)(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)自動(dong)(dong)(dong)(dong)/半(ban)自動(dong)(dong)(dong)(dong)運作。因此我們大約可以(yi)分(fen)為(wei)：短(duan)行(xing)(xing)(xing)(xing)程(cheng)活(huo)(huo)(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)(chang)行(xing)(xing)(xing)(xing)程(cheng)活(huo)(huo)(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣井集(ji)(ji)氣操(cao)作（Gas trap）。槍(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直(zhi)噴式(shi)氣動(dong)(dong)(dong)(dong)操(cao)作（Direct impingement；也稱(cheng)為(wei)Direct Gas Action）。
