氣(qi)(qi)(qi)(qi)(qi)動(dong)操(cao)作(zuo)依照原(yuan)理(li)與不同(tong)槍(qiang)(qiang)枝的(de)(de)機(ji)(ji)械(xie)設(she)計方式(shi)有分為(wei)四種(zhong)五類：第(di)一種(zhong)是(shi)(shi)依賴活(huo)塞(sai)(sai)原(yuan)理(li)進(jin)行(xing)(xing)(xing)(xing)(xing)槍(qiang)(qiang)機(ji)(ji)運(yun)作(zuo)的(de)(de)方式(shi)，亦即透(tou)過(guo)導(dao)流(liu)使氣(qi)(qi)(qi)(qi)(qi)體推動(dong)活(huo)塞(sai)(sai)，活(huo)塞(sai)(sai)連(lian)動(dong)槍(qiang)(qiang)機(ji)(ji)，透(tou)過(guo)這一串的(de)(de)程(cheng)序(xu)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)/半自(zi)(zi)動(dong)運(yun)作(zuo)。然而活(huo)塞(sai)(sai)的(de)(de)運(yun)作(zuo)以(yi)(yi)(yi)行(xing)(xing)(xing)(xing)(xing)程(cheng)為(wei)主，以(yi)(yi)(yi)行(xing)(xing)(xing)(xing)(xing)程(cheng)移動(dong)距離的(de)(de)長(chang)(chang)短(duan)劃(hua)分，而非以(yi)(yi)(yi)活(huo)塞(sai)(sai)的(de)(de)重(zhong)量或者大小劃(hua)分。第(di)二(er)種(zhong)是(shi)(shi)利(li)用(yong)“收集”子(zi)彈(dan)的(de)(de)高壓氣(qi)(qi)(qi)(qi)(qi)之后再導(dao)流(liu)進(jin)入汽缸推動(dong)活(huo)塞(sai)(sai)或整個(ge)槍(qiang)(qiang)管(guan)連(lian)動(dong)到槍(qiang)(qiang)機(ji)(ji)進(jin)行(xing)(xing)(xing)(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)/半自(zi)(zi)動(dong)運(yun)作(zuo)。第(di)三種(zhong)是(shi)(shi)利(li)用(yong)第(di)二(er)種(zhong)“收集”氣(qi)(qi)(qi)(qi)(qi)體的(de)(de)原(yuan)理(li)進(jin)行(xing)(xing)(xing)(xing)(xing)推動(dong)槍(qiang)(qiang)管(guan)連(lian)動(dong)槍(qiang)(qiang)機(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)/半自(zi)(zi)動(dong)運(yun)作(zuo)。后一種(zhong)是(shi)(shi)經(jing)由氣(qi)(qi)(qi)(qi)(qi)導(dao)管(guan)導(dao)流(liu)氣(qi)(qi)(qi)(qi)(qi)體向后“吹送”槍(qiang)(qiang)機(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)枝的(de)(de)自(zi)(zi)動(dong)/半自(zi)(zi)動(dong)運(yun)作(zuo)。因此(ci)我們(men)大約可(ke)以(yi)(yi)(yi)分為(wei)：短(duan)行(xing)(xing)(xing)(xing)(xing)程(cheng)活(huo)塞(sai)(sai)傳動(dong)式(shi)（Short stroke）。長(chang)(chang)行(xing)(xing)(xing)(xing)(xing)程(cheng)活(huo)塞(sai)(sai)傳動(dong)式(shi)（Long stroke）。氣(qi)(qi)(qi)(qi)(qi)井集氣(qi)(qi)(qi)(qi)(qi)操(cao)作(zuo)（Gas trap）。槍(qiang)(qiang)口增壓器（Muzzle booster）。直(zhi)噴式(shi)氣(qi)(qi)(qi)(qi)(qi)動(dong)操(cao)作(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
