氣(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)操作依(yi)照原理與不同槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)機(ji)械設計方式(shi)有分(fen)為(wei)四種(zhong)五類：第一種(zhong)是(shi)(shi)(shi)依(yi)賴活(huo)塞原理進(jin)行(xing)(xing)槍(qiang)(qiang)機(ji)運(yun)(yun)(yun)(yun)作的(de)(de)方式(shi)，亦即透過(guo)導(dao)(dao)流使氣(qi)(qi)(qi)(qi)體推(tui)(tui)動(dong)(dong)(dong)(dong)活(huo)塞，活(huo)塞連(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)，透過(guo)這一串的(de)(de)程序完(wan)成(cheng)(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作。然而(er)活(huo)塞的(de)(de)運(yun)(yun)(yun)(yun)作以(yi)行(xing)(xing)程為(wei)主，以(yi)行(xing)(xing)程移動(dong)(dong)(dong)(dong)距離的(de)(de)長短劃分(fen)，而(er)非以(yi)活(huo)塞的(de)(de)重(zhong)量或(huo)者(zhe)大(da)小劃分(fen)。第二種(zhong)是(shi)(shi)(shi)利(li)用“收集”子彈的(de)(de)高壓氣(qi)(qi)(qi)(qi)之后再(zai)導(dao)(dao)流進(jin)入汽缸推(tui)(tui)動(dong)(dong)(dong)(dong)活(huo)塞或(huo)整個槍(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)到槍(qiang)(qiang)機(ji)進(jin)行(xing)(xing)完(wan)成(cheng)(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作。第三種(zhong)是(shi)(shi)(shi)利(li)用第二種(zhong)“收集”氣(qi)(qi)(qi)(qi)體的(de)(de)原理進(jin)行(xing)(xing)推(tui)(tui)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)完(wan)成(cheng)(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作。后一種(zhong)是(shi)(shi)(shi)經由氣(qi)(qi)(qi)(qi)導(dao)(dao)管導(dao)(dao)流氣(qi)(qi)(qi)(qi)體向后“吹送”槍(qiang)(qiang)機(ji)完(wan)成(cheng)(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)(yun)作。因此(ci)我們(men)大(da)約可以(yi)分(fen)為(wei)：短行(xing)(xing)程活(huo)塞傳動(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)(xing)程活(huo)塞傳動(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)(qi)(qi)(qi)井集氣(qi)(qi)(qi)(qi)操作（Gas trap）。槍(qiang)(qiang)口增壓器（Muzzle booster）。直噴式(shi)氣(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)操作（Direct impingement；也(ye)稱為(wei)Direct Gas Action）。
