氣(qi)(qi)(qi)動(dong)(dong)(dong)操作(zuo)依(yi)(yi)照原理與不(bu)同(tong)槍(qiang)(qiang)枝的(de)(de)機械(xie)設計方式(shi)有分(fen)(fen)為(wei)四種(zhong)(zhong)五類：第(di)一種(zhong)(zhong)是(shi)依(yi)(yi)賴活(huo)塞(sai)(sai)(sai)原理進(jin)行(xing)(xing)槍(qiang)(qiang)機運(yun)(yun)(yun)作(zuo)的(de)(de)方式(shi)，亦即透過導流使氣(qi)(qi)(qi)體(ti)推(tui)動(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)，活(huo)塞(sai)(sai)(sai)連動(dong)(dong)(dong)槍(qiang)(qiang)機，透過這一串的(de)(de)程(cheng)序完成(cheng)槍(qiang)(qiang)枝的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)。然而(er)活(huo)塞(sai)(sai)(sai)的(de)(de)運(yun)(yun)(yun)作(zuo)以(yi)(yi)行(xing)(xing)程(cheng)為(wei)主(zhu)，以(yi)(yi)行(xing)(xing)程(cheng)移動(dong)(dong)(dong)距(ju)離的(de)(de)長短劃分(fen)(fen)，而(er)非以(yi)(yi)活(huo)塞(sai)(sai)(sai)的(de)(de)重量或者大小劃分(fen)(fen)。第(di)二種(zhong)(zhong)是(shi)利用“收集(ji)”子彈的(de)(de)高(gao)壓(ya)(ya)氣(qi)(qi)(qi)之(zhi)后(hou)再導流進(jin)入汽缸(gang)推(tui)動(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)或整(zheng)個(ge)槍(qiang)(qiang)管(guan)連動(dong)(dong)(dong)到槍(qiang)(qiang)機進(jin)行(xing)(xing)完成(cheng)槍(qiang)(qiang)枝的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)。第(di)三種(zhong)(zhong)是(shi)利用第(di)二種(zhong)(zhong)“收集(ji)”氣(qi)(qi)(qi)體(ti)的(de)(de)原理進(jin)行(xing)(xing)推(tui)動(dong)(dong)(dong)槍(qiang)(qiang)管(guan)連動(dong)(dong)(dong)槍(qiang)(qiang)機完成(cheng)槍(qiang)(qiang)枝的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)。后(hou)一種(zhong)(zhong)是(shi)經由氣(qi)(qi)(qi)導管(guan)導流氣(qi)(qi)(qi)體(ti)向后(hou)“吹送(song)”槍(qiang)(qiang)機完成(cheng)槍(qiang)(qiang)枝的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)(yun)作(zuo)。因此我(wo)們大約可以(yi)(yi)分(fen)(fen)為(wei)：短行(xing)(xing)程(cheng)活(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式(shi)（Short stroke）。長行(xing)(xing)程(cheng)活(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)(qi)(qi)井集(ji)氣(qi)(qi)(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)口增壓(ya)(ya)器（Muzzle booster）。直噴(pen)式(shi)氣(qi)(qi)(qi)動(dong)(dong)(dong)操作(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
