氣動(dong)(dong)(dong)操作(zuo)(zuo)(zuo)依照原(yuan)理與不同槍(qiang)枝的(de)(de)機械設計(ji)方式有分為四(si)種(zhong)五類(lei)：第一種(zhong)是(shi)依賴活(huo)塞(sai)原(yuan)理進(jin)行(xing)(xing)(xing)槍(qiang)機運(yun)(yun)作(zuo)(zuo)(zuo)的(de)(de)方式，亦即透過(guo)導流使氣體推動(dong)(dong)(dong)活(huo)塞(sai)，活(huo)塞(sai)連(lian)動(dong)(dong)(dong)槍(qiang)機，透過(guo)這一串(chuan)的(de)(de)程(cheng)序(xu)完(wan)成(cheng)(cheng)槍(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。然而活(huo)塞(sai)的(de)(de)運(yun)(yun)作(zuo)(zuo)(zuo)以(yi)(yi)行(xing)(xing)(xing)程(cheng)為主，以(yi)(yi)行(xing)(xing)(xing)程(cheng)移動(dong)(dong)(dong)距離的(de)(de)長短劃(hua)分，而非以(yi)(yi)活(huo)塞(sai)的(de)(de)重量或者(zhe)大(da)小劃(hua)分。第二(er)種(zhong)是(shi)利(li)用“收集(ji)”子(zi)彈的(de)(de)高壓氣之(zhi)后(hou)再(zai)導流進(jin)入汽(qi)缸推動(dong)(dong)(dong)活(huo)塞(sai)或整個槍(qiang)管連(lian)動(dong)(dong)(dong)到槍(qiang)機進(jin)行(xing)(xing)(xing)完(wan)成(cheng)(cheng)槍(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。第三種(zhong)是(shi)利(li)用第二(er)種(zhong)“收集(ji)”氣體的(de)(de)原(yuan)理進(jin)行(xing)(xing)(xing)推動(dong)(dong)(dong)槍(qiang)管連(lian)動(dong)(dong)(dong)槍(qiang)機完(wan)成(cheng)(cheng)槍(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。后(hou)一種(zhong)是(shi)經由氣導管導流氣體向后(hou)“吹(chui)送”槍(qiang)機完(wan)成(cheng)(cheng)槍(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)(zuo)。因此我們大(da)約可(ke)以(yi)(yi)分為：短行(xing)(xing)(xing)程(cheng)活(huo)塞(sai)傳(chuan)(chuan)動(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)(xing)程(cheng)活(huo)塞(sai)傳(chuan)(chuan)動(dong)(dong)(dong)式（Long stroke）。氣井集(ji)氣操作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)口增壓器（Muzzle booster）。直噴式氣動(dong)(dong)(dong)操作(zuo)(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
