氣(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)依照原理與不同槍(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)(de)機械設計方(fang)式(shi)有(you)分為四種(zhong)五(wu)類(lei)：第一種(zhong)是(shi)依賴活塞(sai)(sai)原理進(jin)行(xing)槍(qiang)(qiang)(qiang)機運(yun)作(zuo)的(de)(de)(de)(de)(de)方(fang)式(shi)，亦即透過導流使氣(qi)體(ti)推(tui)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)，活塞(sai)(sai)連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機，透過這一串的(de)(de)(de)(de)(de)程序完(wan)成槍(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。然而(er)活塞(sai)(sai)的(de)(de)(de)(de)(de)運(yun)作(zuo)以(yi)行(xing)程為主(zhu)，以(yi)行(xing)程移動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)距離(li)的(de)(de)(de)(de)(de)長(chang)短劃分，而(er)非以(yi)活塞(sai)(sai)的(de)(de)(de)(de)(de)重量或者大(da)小劃分。第二種(zhong)是(shi)利用“收集(ji)”子彈(dan)的(de)(de)(de)(de)(de)高(gao)壓氣(qi)之后再導流進(jin)入汽缸推(tui)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)或整個槍(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機進(jin)行(xing)完(wan)成槍(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。第三種(zhong)是(shi)利用第二種(zhong)“收集(ji)”氣(qi)體(ti)的(de)(de)(de)(de)(de)原理進(jin)行(xing)推(tui)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機完(wan)成槍(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。后一種(zhong)是(shi)經(jing)由氣(qi)導管(guan)導流氣(qi)體(ti)向后“吹(chui)送”槍(qiang)(qiang)(qiang)機完(wan)成槍(qiang)(qiang)(qiang)枝的(de)(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。因此我們大(da)約可(ke)以(yi)分為：短行(xing)程活塞(sai)(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)行(xing)程活塞(sai)(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井(jing)集(ji)氣(qi)操作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口增(zeng)壓器(qi)（Muzzle booster）。直噴式(shi)氣(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)操作(zuo)（Direct impingement；也(ye)稱為Direct Gas Action）。
