氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作依照(zhao)原(yuan)(yuan)理(li)與不同槍(qiang)枝(zhi)的(de)(de)(de)(de)機械設(she)計(ji)方式(shi)(shi)有分(fen)為四種五類：第一(yi)種是依賴活塞原(yuan)(yuan)理(li)進(jin)(jin)(jin)行(xing)(xing)槍(qiang)機運(yun)作的(de)(de)(de)(de)方式(shi)(shi)，亦即透過(guo)(guo)導(dao)流(liu)使(shi)氣(qi)(qi)(qi)體(ti)推(tui)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞，活塞連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)機，透過(guo)(guo)這一(yi)串的(de)(de)(de)(de)程(cheng)序完成槍(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作。然而活塞的(de)(de)(de)(de)運(yun)作以(yi)行(xing)(xing)程(cheng)為主，以(yi)行(xing)(xing)程(cheng)移動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)距(ju)離的(de)(de)(de)(de)長(chang)短劃分(fen)，而非以(yi)活塞的(de)(de)(de)(de)重(zhong)量(liang)或者大(da)小劃分(fen)。第二種是利用“收集(ji)(ji)”子彈的(de)(de)(de)(de)高壓氣(qi)(qi)(qi)之(zhi)后(hou)(hou)再導(dao)流(liu)進(jin)(jin)(jin)入汽缸推(tui)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞或整個槍(qiang)管(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)機進(jin)(jin)(jin)行(xing)(xing)完成槍(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作。第三種是利用第二種“收集(ji)(ji)”氣(qi)(qi)(qi)體(ti)的(de)(de)(de)(de)原(yuan)(yuan)理(li)進(jin)(jin)(jin)行(xing)(xing)推(tui)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)管(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)機完成槍(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作。后(hou)(hou)一(yi)種是經由氣(qi)(qi)(qi)導(dao)管(guan)導(dao)流(liu)氣(qi)(qi)(qi)體(ti)向(xiang)后(hou)(hou)“吹送(song)”槍(qiang)機完成槍(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作。因此我們大(da)約可(ke)以(yi)分(fen)為：短行(xing)(xing)程(cheng)活塞傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長(chang)行(xing)(xing)程(cheng)活塞傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)(qi)(qi)井集(ji)(ji)氣(qi)(qi)(qi)操作（Gas trap）。槍(qiang)口增壓器（Muzzle booster）。直噴式(shi)(shi)氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作（Direct impingement；也稱為Direct Gas Action）。
