氣動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)依(yi)照原理與(yu)不同槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)機(ji)(ji)械(xie)設計(ji)方式(shi)有分(fen)(fen)為(wei)四種(zhong)(zhong)五類：第一種(zhong)(zhong)是(shi)依(yi)賴活(huo)塞(sai)原理進(jin)行(xing)槍(qiang)(qiang)機(ji)(ji)運(yun)作(zuo)的(de)(de)方式(shi)，亦即透(tou)過導(dao)(dao)(dao)流(liu)使氣體推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)，活(huo)塞(sai)連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)(ji)，透(tou)過這一串的(de)(de)程(cheng)序完成槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。然而(er)活(huo)塞(sai)的(de)(de)運(yun)作(zuo)以行(xing)程(cheng)為(wei)主，以行(xing)程(cheng)移動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)距離的(de)(de)長(chang)短劃(hua)分(fen)(fen)，而(er)非以活(huo)塞(sai)的(de)(de)重量或者大(da)小劃(hua)分(fen)(fen)。第二種(zhong)(zhong)是(shi)利(li)用“收集”子彈(dan)的(de)(de)高壓(ya)氣之后(hou)再導(dao)(dao)(dao)流(liu)進(jin)入汽缸推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)或整個槍(qiang)(qiang)管連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)機(ji)(ji)進(jin)行(xing)完成槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。第三(san)種(zhong)(zhong)是(shi)利(li)用第二種(zhong)(zhong)“收集”氣體的(de)(de)原理進(jin)行(xing)推動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)管連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)(ji)完成槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。后(hou)一種(zhong)(zhong)是(shi)經由氣導(dao)(dao)(dao)管導(dao)(dao)(dao)流(liu)氣體向后(hou)“吹送(song)”槍(qiang)(qiang)機(ji)(ji)完成槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。因此我們大(da)約可以分(fen)(fen)為(wei)：短行(xing)程(cheng)活(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)行(xing)程(cheng)活(huo)塞(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣井集氣操作(zuo)（Gas trap）。槍(qiang)(qiang)口(kou)增壓(ya)器（Muzzle booster）。直噴式(shi)氣動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)（Direct impingement；也稱(cheng)為(wei)Direct Gas Action）。
