氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)依(yi)照原理(li)(li)與不同槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的機(ji)械(xie)設計方(fang)式(shi)(shi)(shi)有分為(wei)四種(zhong)五類：第(di)(di)一(yi)種(zhong)是(shi)(shi)依(yi)賴(lai)活(huo)(huo)塞(sai)(sai)(sai)原理(li)(li)進(jin)行槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)運(yun)(yun)作(zuo)(zuo)的方(fang)式(shi)(shi)(shi)，亦即透過(guo)導(dao)流使氣(qi)體推(tui)動(dong)(dong)(dong)活(huo)(huo)塞(sai)(sai)(sai)，活(huo)(huo)塞(sai)(sai)(sai)連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)，透過(guo)這一(yi)串的程(cheng)(cheng)(cheng)序完(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的自(zi)(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。然而活(huo)(huo)塞(sai)(sai)(sai)的運(yun)(yun)作(zuo)(zuo)以(yi)(yi)行程(cheng)(cheng)(cheng)為(wei)主，以(yi)(yi)行程(cheng)(cheng)(cheng)移動(dong)(dong)(dong)距離的長(chang)短(duan)劃分，而非(fei)以(yi)(yi)活(huo)(huo)塞(sai)(sai)(sai)的重量或者(zhe)大小劃分。第(di)(di)二(er)(er)種(zhong)是(shi)(shi)利用“收(shou)集”子(zi)彈的高壓氣(qi)之后再導(dao)流進(jin)入汽缸推(tui)動(dong)(dong)(dong)活(huo)(huo)塞(sai)(sai)(sai)或整個槍(qiang)(qiang)(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)到(dao)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)進(jin)行完(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的自(zi)(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。第(di)(di)三種(zhong)是(shi)(shi)利用第(di)(di)二(er)(er)種(zhong)“收(shou)集”氣(qi)體的原理(li)(li)進(jin)行推(tui)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的自(zi)(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。后一(yi)種(zhong)是(shi)(shi)經由氣(qi)導(dao)管導(dao)流氣(qi)體向后“吹送”槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)完(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的自(zi)(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)(zi)動(dong)(dong)(dong)運(yun)(yun)作(zuo)(zuo)。因(yin)此(ci)我們大約可以(yi)(yi)分為(wei)：短(duan)行程(cheng)(cheng)(cheng)活(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式(shi)(shi)(shi)（Short stroke）。長(chang)行程(cheng)(cheng)(cheng)活(huo)(huo)塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)式(shi)(shi)(shi)（Long stroke）。氣(qi)井集氣(qi)操(cao)作(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直(zhi)噴式(shi)(shi)(shi)氣(qi)動(dong)(dong)(dong)操(cao)作(zuo)(zuo)（Direct impingement；也稱為(wei)Direct Gas Action）。
