氣(qi)動(dong)(dong)(dong)操(cao)作依照原(yuan)理(li)與不(bu)同槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)機(ji)(ji)械(xie)設計方式有分為四種(zhong)(zhong)(zhong)五類：第(di)一種(zhong)(zhong)(zhong)是(shi)依賴活(huo)(huo)(huo)(huo)塞原(yuan)理(li)進行(xing)槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)運作的(de)(de)(de)(de)方式，亦(yi)即透過導(dao)流使氣(qi)體推(tui)動(dong)(dong)(dong)活(huo)(huo)(huo)(huo)塞，活(huo)(huo)(huo)(huo)塞連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)，透過這一串的(de)(de)(de)(de)程(cheng)(cheng)序(xu)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作。然而(er)活(huo)(huo)(huo)(huo)塞的(de)(de)(de)(de)運作以(yi)(yi)行(xing)程(cheng)(cheng)為主，以(yi)(yi)行(xing)程(cheng)(cheng)移動(dong)(dong)(dong)距離的(de)(de)(de)(de)長短劃(hua)分，而(er)非以(yi)(yi)活(huo)(huo)(huo)(huo)塞的(de)(de)(de)(de)重量或(huo)者大(da)小(xiao)劃(hua)分。第(di)二種(zhong)(zhong)(zhong)是(shi)利用“收(shou)(shou)集(ji)”子彈的(de)(de)(de)(de)高壓氣(qi)之(zhi)后再導(dao)流進入汽缸推(tui)動(dong)(dong)(dong)活(huo)(huo)(huo)(huo)塞或(huo)整(zheng)個(ge)槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)進行(xing)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作。第(di)三種(zhong)(zhong)(zhong)是(shi)利用第(di)二種(zhong)(zhong)(zhong)“收(shou)(shou)集(ji)”氣(qi)體的(de)(de)(de)(de)原(yuan)理(li)進行(xing)推(tui)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連(lian)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作。后一種(zhong)(zhong)(zhong)是(shi)經由氣(qi)導(dao)管(guan)導(dao)流氣(qi)體向后“吹送”槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完(wan)(wan)成槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)(de)(de)自(zi)動(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)運作。因此我們大(da)約可(ke)以(yi)(yi)分為：短行(xing)程(cheng)(cheng)活(huo)(huo)(huo)(huo)塞傳(chuan)動(dong)(dong)(dong)式（Short stroke）。長行(xing)程(cheng)(cheng)活(huo)(huo)(huo)(huo)塞傳(chuan)動(dong)(dong)(dong)式（Long stroke）。氣(qi)井(jing)集(ji)氣(qi)操(cao)作（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直噴式氣(qi)動(dong)(dong)(dong)操(cao)作（Direct impingement；也稱(cheng)為Direct Gas Action）。
