氣(qi)動(dong)(dong)(dong)操(cao)(cao)作依(yi)照(zhao)原理(li)與不(bu)同(tong)槍(qiang)(qiang)(qiang)枝的(de)(de)機(ji)(ji)械設計方式有分(fen)為(wei)(wei)四種(zhong)(zhong)(zhong)(zhong)五(wu)類：第(di)(di)一種(zhong)(zhong)(zhong)(zhong)是依(yi)賴活(huo)(huo)(huo)塞(sai)(sai)(sai)原理(li)進行(xing)槍(qiang)(qiang)(qiang)機(ji)(ji)運作的(de)(de)方式，亦(yi)即(ji)透(tou)過(guo)導(dao)(dao)流(liu)使氣(qi)體(ti)推動(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)(sai)(sai)，活(huo)(huo)(huo)塞(sai)(sai)(sai)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)，透(tou)過(guo)這一串的(de)(de)程(cheng)(cheng)(cheng)序完成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作。然而(er)活(huo)(huo)(huo)塞(sai)(sai)(sai)的(de)(de)運作以(yi)(yi)行(xing)程(cheng)(cheng)(cheng)為(wei)(wei)主，以(yi)(yi)行(xing)程(cheng)(cheng)(cheng)移動(dong)(dong)(dong)距離(li)的(de)(de)長短(duan)劃分(fen)，而(er)非以(yi)(yi)活(huo)(huo)(huo)塞(sai)(sai)(sai)的(de)(de)重(zhong)量或(huo)者大小劃分(fen)。第(di)(di)二(er)種(zhong)(zhong)(zhong)(zhong)是利(li)用“收集(ji)(ji)”子彈的(de)(de)高壓(ya)氣(qi)之后再導(dao)(dao)流(liu)進入汽缸(gang)推動(dong)(dong)(dong)活(huo)(huo)(huo)塞(sai)(sai)(sai)或(huo)整個槍(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)(ji)進行(xing)完成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作。第(di)(di)三種(zhong)(zhong)(zhong)(zhong)是利(li)用第(di)(di)二(er)種(zhong)(zhong)(zhong)(zhong)“收集(ji)(ji)”氣(qi)體(ti)的(de)(de)原理(li)進行(xing)推動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)(ji)完成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作。后一種(zhong)(zhong)(zhong)(zhong)是經由氣(qi)導(dao)(dao)管導(dao)(dao)流(liu)氣(qi)體(ti)向后“吹送(song)”槍(qiang)(qiang)(qiang)機(ji)(ji)完成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作。因此我們大約可以(yi)(yi)分(fen)為(wei)(wei)：短(duan)行(xing)程(cheng)(cheng)(cheng)活(huo)(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式（Short stroke）。長行(xing)程(cheng)(cheng)(cheng)活(huo)(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式（Long stroke）。氣(qi)井集(ji)(ji)氣(qi)操(cao)(cao)作（Gas trap）。槍(qiang)(qiang)(qiang)口增壓(ya)器（Muzzle booster）。直噴式氣(qi)動(dong)(dong)(dong)操(cao)(cao)作（Direct impingement；也稱為(wei)(wei)Direct Gas Action）。
