氣動(dong)(dong)操作(zuo)(zuo)(zuo)依(yi)照(zhao)原理與(yu)不同(tong)槍(qiang)(qiang)枝(zhi)的(de)(de)機(ji)(ji)(ji)械設計方式(shi)(shi)(shi)有(you)分為四種(zhong)(zhong)五類(lei)：第一(yi)種(zhong)(zhong)是(shi)(shi)依(yi)賴活塞(sai)原理進(jin)(jin)行(xing)(xing)槍(qiang)(qiang)機(ji)(ji)(ji)運作(zuo)(zuo)(zuo)的(de)(de)方式(shi)(shi)(shi)，亦(yi)即透過導(dao)流(liu)使氣體推(tui)(tui)動(dong)(dong)活塞(sai)，活塞(sai)連動(dong)(dong)槍(qiang)(qiang)機(ji)(ji)(ji)，透過這一(yi)串的(de)(de)程(cheng)(cheng)(cheng)序完成(cheng)槍(qiang)(qiang)枝(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)/半(ban)自(zi)(zi)(zi)動(dong)(dong)運作(zuo)(zuo)(zuo)。然而活塞(sai)的(de)(de)運作(zuo)(zuo)(zuo)以(yi)(yi)行(xing)(xing)程(cheng)(cheng)(cheng)為主，以(yi)(yi)行(xing)(xing)程(cheng)(cheng)(cheng)移動(dong)(dong)距離的(de)(de)長短劃分，而非(fei)以(yi)(yi)活塞(sai)的(de)(de)重量或者大小劃分。第二種(zhong)(zhong)是(shi)(shi)利(li)用“收集(ji)”子(zi)彈(dan)的(de)(de)高壓(ya)(ya)氣之后(hou)再導(dao)流(liu)進(jin)(jin)入汽缸(gang)推(tui)(tui)動(dong)(dong)活塞(sai)或整個槍(qiang)(qiang)管連動(dong)(dong)到(dao)槍(qiang)(qiang)機(ji)(ji)(ji)進(jin)(jin)行(xing)(xing)完成(cheng)槍(qiang)(qiang)枝(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)/半(ban)自(zi)(zi)(zi)動(dong)(dong)運作(zuo)(zuo)(zuo)。第三種(zhong)(zhong)是(shi)(shi)利(li)用第二種(zhong)(zhong)“收集(ji)”氣體的(de)(de)原理進(jin)(jin)行(xing)(xing)推(tui)(tui)動(dong)(dong)槍(qiang)(qiang)管連動(dong)(dong)槍(qiang)(qiang)機(ji)(ji)(ji)完成(cheng)槍(qiang)(qiang)枝(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)/半(ban)自(zi)(zi)(zi)動(dong)(dong)運作(zuo)(zuo)(zuo)。后(hou)一(yi)種(zhong)(zhong)是(shi)(shi)經由氣導(dao)管導(dao)流(liu)氣體向后(hou)“吹(chui)送(song)”槍(qiang)(qiang)機(ji)(ji)(ji)完成(cheng)槍(qiang)(qiang)枝(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)/半(ban)自(zi)(zi)(zi)動(dong)(dong)運作(zuo)(zuo)(zuo)。因此我們大約可以(yi)(yi)分為：短行(xing)(xing)程(cheng)(cheng)(cheng)活塞(sai)傳動(dong)(dong)式(shi)(shi)(shi)（Short stroke）。長行(xing)(xing)程(cheng)(cheng)(cheng)活塞(sai)傳動(dong)(dong)式(shi)(shi)(shi)（Long stroke）。氣井集(ji)氣操作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)口增壓(ya)(ya)器（Muzzle booster）。直噴式(shi)(shi)(shi)氣動(dong)(dong)操作(zuo)(zuo)(zuo)（Direct impingement；也稱為Direct Gas Action）。
