氣(qi)動(dong)(dong)(dong)(dong)操作依(yi)照(zhao)原理(li)與不同槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)機械設(she)計方(fang)式(shi)有分(fen)為(wei)四種(zhong)五類：第一(yi)種(zhong)是依(yi)賴(lai)活塞(sai)(sai)(sai)原理(li)進(jin)(jin)行(xing)槍(qiang)(qiang)(qiang)機運(yun)(yun)(yun)作的(de)(de)(de)(de)方(fang)式(shi)，亦即透過導(dao)流(liu)(liu)使氣(qi)體推(tui)(tui)動(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)，活塞(sai)(sai)(sai)連(lian)(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機，透過這一(yi)串的(de)(de)(de)(de)程序完(wan)(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作。然(ran)而(er)活塞(sai)(sai)(sai)的(de)(de)(de)(de)運(yun)(yun)(yun)作以行(xing)程為(wei)主，以行(xing)程移動(dong)(dong)(dong)(dong)距離的(de)(de)(de)(de)長(chang)短(duan)劃(hua)分(fen)，而(er)非以活塞(sai)(sai)(sai)的(de)(de)(de)(de)重(zhong)量或(huo)者大小劃(hua)分(fen)。第二種(zhong)是利用“收集”子彈的(de)(de)(de)(de)高壓(ya)氣(qi)之后再導(dao)流(liu)(liu)進(jin)(jin)入汽(qi)缸推(tui)(tui)動(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)或(huo)整個槍(qiang)(qiang)(qiang)管(guan)連(lian)(lian)動(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機進(jin)(jin)行(xing)完(wan)(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作。第三種(zhong)是利用第二種(zhong)“收集”氣(qi)體的(de)(de)(de)(de)原理(li)進(jin)(jin)行(xing)推(tui)(tui)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管(guan)連(lian)(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機完(wan)(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作。后一(yi)種(zhong)是經由氣(qi)導(dao)管(guan)導(dao)流(liu)(liu)氣(qi)體向后“吹送”槍(qiang)(qiang)(qiang)機完(wan)(wan)成槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)運(yun)(yun)(yun)作。因此我們大約(yue)可以分(fen)為(wei)：短(duan)行(xing)程活塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)行(xing)程活塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)井(jing)集氣(qi)操作（Gas trap）。槍(qiang)(qiang)(qiang)口增(zeng)壓(ya)器（Muzzle booster）。直噴(pen)式(shi)氣(qi)動(dong)(dong)(dong)(dong)操作（Direct impingement；也稱為(wei)Direct Gas Action）。
