氣(qi)(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)依(yi)照原(yuan)理與不同槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)的(de)(de)機(ji)械設計方式(shi)(shi)有分(fen)為四種五類：第(di)一(yi)(yi)種是依(yi)賴活塞原(yuan)理進(jin)行(xing)槍(qiang)(qiang)(qiang)機(ji)運(yun)作(zuo)(zuo)的(de)(de)方式(shi)(shi)，亦即(ji)透(tou)過導(dao)(dao)流使氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)推動(dong)(dong)(dong)(dong)(dong)活塞，活塞連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透(tou)過這一(yi)(yi)串的(de)(de)程序完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)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(ran)而活塞的(de)(de)運(yun)作(zuo)(zuo)以(yi)行(xing)程為主(zhu)，以(yi)行(xing)程移動(dong)(dong)(dong)(dong)(dong)距離(li)的(de)(de)長短劃分(fen)，而非以(yi)活塞的(de)(de)重(zhong)量或(huo)者大(da)小劃分(fen)。第(di)二種是利用“收集(ji)”子彈的(de)(de)高壓氣(qi)(qi)(qi)(qi)(qi)之后再導(dao)(dao)流進(jin)入汽缸(gang)推動(dong)(dong)(dong)(dong)(dong)活塞或(huo)整個槍(qiang)(qiang)(qiang)管(guan)(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進(jin)行(xing)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)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(di)三(san)種是利用第(di)二種“收集(ji)”氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)的(de)(de)原(yuan)理進(jin)行(xing)推動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管(guan)(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)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)(yi)種是經由(you)氣(qi)(qi)(qi)(qi)(qi)導(dao)(dao)管(guan)(guan)導(dao)(dao)流氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)向后“吹(chui)送”槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)(zhi)(zhi)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)約可以(yi)分(fen)為：短行(xing)程活塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長行(xing)程活塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)(qi)(qi)(qi)(qi)井集(ji)氣(qi)(qi)(qi)(qi)(qi)操(cao)作(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直(zhi)噴式(shi)(shi)氣(qi)(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
