氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)依(yi)照(zhao)原理(li)與不同槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)機(ji)(ji)械設(she)計方(fang)式(shi)(shi)有分為(wei)(wei)四種(zhong)(zhong)五(wu)類：第一(yi)種(zhong)(zhong)是(shi)依(yi)賴活塞原理(li)進(jin)行槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)運(yun)作(zuo)(zuo)的(de)(de)方(fang)式(shi)(shi)，亦(yi)即透過導(dao)(dao)流(liu)(liu)使氣(qi)體推(tui)動(dong)(dong)(dong)(dong)(dong)活塞，活塞連動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)，透過這一(yi)串的(de)(de)程(cheng)序完(wan)成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。然而活塞的(de)(de)運(yun)作(zuo)(zuo)以(yi)行程(cheng)為(wei)(wei)主，以(yi)行程(cheng)移動(dong)(dong)(dong)(dong)(dong)距(ju)離的(de)(de)長短劃(hua)分，而非以(yi)活塞的(de)(de)重(zhong)量或者大(da)小劃(hua)分。第二種(zhong)(zhong)是(shi)利(li)(li)用“收集”子彈的(de)(de)高壓氣(qi)之后再導(dao)(dao)流(liu)(liu)進(jin)入汽缸推(tui)動(dong)(dong)(dong)(dong)(dong)活塞或整個槍(qiang)(qiang)(qiang)(qiang)管(guan)(guan)(guan)連動(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)進(jin)行完(wan)成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。第三種(zhong)(zhong)是(shi)利(li)(li)用第二種(zhong)(zhong)“收集”氣(qi)體的(de)(de)原理(li)進(jin)行推(tui)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)管(guan)(guan)(guan)連動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。后一(yi)種(zhong)(zhong)是(shi)經由氣(qi)導(dao)(dao)管(guan)(guan)(guan)導(dao)(dao)流(liu)(liu)氣(qi)體向后“吹送(song)”槍(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)成槍(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。因此我們大(da)約(yue)可以(yi)分為(wei)(wei)：短行程(cheng)活塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長行程(cheng)活塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)井(jing)集氣(qi)操作(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直噴(pen)式(shi)(shi)氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)（Direct impingement；也稱為(wei)(wei)Direct Gas Action）。
