氣動(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)依照原理(li)與不同(tong)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)機(ji)(ji)械設計方式(shi)有分(fen)為四種五類(lei)：第(di)一(yi)種是(shi)依賴活(huo)塞(sai)(sai)(sai)原理(li)進(jin)行槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)運(yun)作(zuo)(zuo)(zuo)的(de)(de)方式(shi)，亦即(ji)透(tou)過(guo)導流使氣體推動(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)，活(huo)塞(sai)(sai)(sai)連動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)，透(tou)過(guo)這一(yi)串的(de)(de)程(cheng)序完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。然而活(huo)塞(sai)(sai)(sai)的(de)(de)運(yun)作(zuo)(zuo)(zuo)以(yi)行程(cheng)為主，以(yi)行程(cheng)移動(dong)(dong)(dong)(dong)距離的(de)(de)長(chang)(chang)短劃(hua)分(fen)，而非以(yi)活(huo)塞(sai)(sai)(sai)的(de)(de)重量(liang)或者大(da)小劃(hua)分(fen)。第(di)二種是(shi)利用(yong)“收(shou)(shou)集”子彈的(de)(de)高壓氣之(zhi)后再導流進(jin)入汽缸推動(dong)(dong)(dong)(dong)活(huo)塞(sai)(sai)(sai)或整個槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)到(dao)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)進(jin)行完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。第(di)三(san)種是(shi)利用(yong)第(di)二種“收(shou)(shou)集”氣體的(de)(de)原理(li)進(jin)行推動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。后一(yi)種是(shi)經由(you)氣導管(guan)導流氣體向后“吹送”槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。因此(ci)我們大(da)約可以(yi)分(fen)為：短行程(cheng)活(huo)塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)(chang)行程(cheng)活(huo)塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣井集氣操作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)(qiang)口(kou)增壓器（Muzzle booster）。直噴式(shi)氣動(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
