氣動(dong)(dong)(dong)(dong)操作依(yi)照(zhao)原理(li)與不同槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)機(ji)械設計方式有分(fen)為(wei)四種(zhong)(zhong)五類：第(di)(di)一種(zhong)(zhong)是(shi)(shi)依(yi)賴活(huo)(huo)塞(sai)原理(li)進行(xing)(xing)(xing)槍(qiang)(qiang)機(ji)運作的(de)(de)方式，亦即透過(guo)導流使氣體推(tui)動(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)，活(huo)(huo)塞(sai)連(lian)(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)，透過(guo)這一串的(de)(de)程序完(wan)成(cheng)(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)運作。然(ran)而活(huo)(huo)塞(sai)的(de)(de)運作以行(xing)(xing)(xing)程為(wei)主(zhu)，以行(xing)(xing)(xing)程移動(dong)(dong)(dong)(dong)距離的(de)(de)長(chang)短劃(hua)分(fen)，而非以活(huo)(huo)塞(sai)的(de)(de)重量或(huo)者(zhe)大小劃(hua)分(fen)。第(di)(di)二種(zhong)(zhong)是(shi)(shi)利用“收(shou)集”子彈的(de)(de)高壓氣之后再導流進入汽(qi)缸推(tui)動(dong)(dong)(dong)(dong)活(huo)(huo)塞(sai)或(huo)整個槍(qiang)(qiang)管連(lian)(lian)動(dong)(dong)(dong)(dong)到槍(qiang)(qiang)機(ji)進行(xing)(xing)(xing)完(wan)成(cheng)(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)運作。第(di)(di)三種(zhong)(zhong)是(shi)(shi)利用第(di)(di)二種(zhong)(zhong)“收(shou)集”氣體的(de)(de)原理(li)進行(xing)(xing)(xing)推(tui)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)管連(lian)(lian)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)機(ji)完(wan)成(cheng)(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)運作。后一種(zhong)(zhong)是(shi)(shi)經(jing)由氣導管導流氣體向(xiang)后“吹送”槍(qiang)(qiang)機(ji)完(wan)成(cheng)(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)/半自(zi)(zi)(zi)動(dong)(dong)(dong)(dong)運作。因此我(wo)們(men)大約可以分(fen)為(wei)：短行(xing)(xing)(xing)程活(huo)(huo)塞(sai)傳動(dong)(dong)(dong)(dong)式（Short stroke）。長(chang)行(xing)(xing)(xing)程活(huo)(huo)塞(sai)傳動(dong)(dong)(dong)(dong)式（Long stroke）。氣井集氣操作（Gas trap）。槍(qiang)(qiang)口增壓器（Muzzle booster）。直(zhi)噴式氣動(dong)(dong)(dong)(dong)操作（Direct impingement；也(ye)稱(cheng)為(wei)Direct Gas Action）。
