氣(qi)(qi)動(dong)(dong)(dong)(dong)(dong)操(cao)(cao)作(zuo)依照原理與不同(tong)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)機(ji)(ji)械設(she)計方式有分(fen)為四(si)種五類：第一種是(shi)依賴活(huo)塞原理進行(xing)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)運(yun)作(zuo)的(de)(de)方式，亦即透過(guo)導流使氣(qi)(qi)體(ti)推(tui)(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)塞，活(huo)塞連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)，透過(guo)這一串的(de)(de)程(cheng)(cheng)序完成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。然而活(huo)塞的(de)(de)運(yun)作(zuo)以(yi)行(xing)程(cheng)(cheng)為主，以(yi)行(xing)程(cheng)(cheng)移動(dong)(dong)(dong)(dong)(dong)距(ju)離的(de)(de)長短劃(hua)分(fen)，而非(fei)以(yi)活(huo)塞的(de)(de)重量或(huo)者大(da)小(xiao)劃(hua)分(fen)。第二種是(shi)利用“收(shou)集(ji)(ji)”子(zi)彈的(de)(de)高壓氣(qi)(qi)之后再導流進入汽(qi)缸推(tui)(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)塞或(huo)整(zheng)個槍(qiang)(qiang)(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)進行(xing)完成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。第三種是(shi)利用第二種“收(shou)集(ji)(ji)”氣(qi)(qi)體(ti)的(de)(de)原理進行(xing)推(tui)(tui)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。后一種是(shi)經由氣(qi)(qi)導管導流氣(qi)(qi)體(ti)向后“吹送”槍(qiang)(qiang)(qiang)(qiang)(qiang)機(ji)(ji)完成(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)。因(yin)此(ci)我們大(da)約可以(yi)分(fen)為：短行(xing)程(cheng)(cheng)活(huo)塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長行(xing)程(cheng)(cheng)活(huo)塞傳(chuan)動(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)井集(ji)(ji)氣(qi)(qi)操(cao)(cao)作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)(qiang)口增(zeng)壓器(qi)（Muzzle booster）。直噴式氣(qi)(qi)動(dong)(dong)(dong)(dong)(dong)操(cao)(cao)作(zuo)（Direct impingement；也稱為Direct Gas Action）。
