氣(qi)(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)依照原理與不同槍(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)機(ji)械(xie)設計方(fang)式(shi)有分為(wei)四種(zhong)(zhong)(zhong)五類：第(di)一(yi)種(zhong)(zhong)(zhong)是依賴活(huo)塞(sai)(sai)原理進(jin)行(xing)槍(qiang)(qiang)機(ji)運(yun)(yun)作(zuo)的(de)方(fang)式(shi)，亦即透過(guo)導流(liu)使氣(qi)(qi)體(ti)推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)，活(huo)塞(sai)(sai)連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)，透過(guo)這一(yi)串的(de)程(cheng)序(xu)完成槍(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。然而活(huo)塞(sai)(sai)的(de)運(yun)(yun)作(zuo)以行(xing)程(cheng)為(wei)主，以行(xing)程(cheng)移(yi)動(dong)(dong)(dong)(dong)(dong)距(ju)離的(de)長(chang)(chang)短(duan)劃分，而非(fei)以活(huo)塞(sai)(sai)的(de)重量或者(zhe)大小劃分。第(di)二(er)種(zhong)(zhong)(zhong)是利用“收集(ji)”子彈的(de)高(gao)壓(ya)氣(qi)(qi)之后再導流(liu)進(jin)入汽(qi)缸推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)或整個槍(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)機(ji)進(jin)行(xing)完成槍(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。第(di)三種(zhong)(zhong)(zhong)是利用第(di)二(er)種(zhong)(zhong)(zhong)“收集(ji)”氣(qi)(qi)體(ti)的(de)原理進(jin)行(xing)推(tui)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)完成槍(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。后一(yi)種(zhong)(zhong)(zhong)是經由氣(qi)(qi)導管導流(liu)氣(qi)(qi)體(ti)向后“吹送”槍(qiang)(qiang)機(ji)完成槍(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)(ban)(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。因此(ci)我們大約可(ke)以分為(wei)：短(duan)行(xing)程(cheng)活(huo)塞(sai)(sai)傳動(dong)(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)(chang)行(xing)程(cheng)活(huo)塞(sai)(sai)傳動(dong)(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)(qi)井(jing)集(ji)氣(qi)(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)口增壓(ya)器（Muzzle booster）。直噴式(shi)氣(qi)(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
