氣(qi)動(dong)(dong)操作(zuo)依照原(yuan)(yuan)理(li)與(yu)不同槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)機械(xie)設計方式(shi)有分(fen)(fen)為(wei)(wei)四種五類：第一種是(shi)依賴活(huo)塞原(yuan)(yuan)理(li)進(jin)(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)(qiang)(qiang)機運作(zuo)的(de)(de)(de)(de)方式(shi)，亦即透過導流使(shi)氣(qi)體推動(dong)(dong)活(huo)塞，活(huo)塞連(lian)動(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機，透過這一串的(de)(de)(de)(de)程(cheng)序完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)/半自(zi)(zi)動(dong)(dong)運作(zuo)。然而活(huo)塞的(de)(de)(de)(de)運作(zuo)以行(xing)(xing)程(cheng)為(wei)(wei)主，以行(xing)(xing)程(cheng)移動(dong)(dong)距離的(de)(de)(de)(de)長短(duan)劃分(fen)(fen)，而非以活(huo)塞的(de)(de)(de)(de)重(zhong)量或者大小(xiao)劃分(fen)(fen)。第二(er)種是(shi)利(li)用“收集(ji)”子彈的(de)(de)(de)(de)高壓(ya)(ya)氣(qi)之后再導流進(jin)(jin)入汽缸推動(dong)(dong)活(huo)塞或整個槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)(qiang)機進(jin)(jin)行(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)/半自(zi)(zi)動(dong)(dong)運作(zuo)。第三種是(shi)利(li)用第二(er)種“收集(ji)”氣(qi)體的(de)(de)(de)(de)原(yuan)(yuan)理(li)進(jin)(jin)行(xing)(xing)推動(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)/半自(zi)(zi)動(dong)(dong)運作(zuo)。后一種是(shi)經由氣(qi)導管(guan)導流氣(qi)體向后“吹送”槍(qiang)(qiang)(qiang)(qiang)(qiang)機完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)/半自(zi)(zi)動(dong)(dong)運作(zuo)。因此我(wo)們(men)大約可以分(fen)(fen)為(wei)(wei)：短(duan)行(xing)(xing)程(cheng)活(huo)塞傳(chuan)動(dong)(dong)式(shi)（Short stroke）。長行(xing)(xing)程(cheng)活(huo)塞傳(chuan)動(dong)(dong)式(shi)（Long stroke）。氣(qi)井集(ji)氣(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)(qiang)口(kou)增壓(ya)(ya)器（Muzzle booster）。直噴式(shi)氣(qi)動(dong)(dong)操作(zuo)（Direct impingement；也稱(cheng)為(wei)(wei)Direct Gas Action）。
