氣(qi)(qi)(qi)動(dong)(dong)(dong)操(cao)(cao)作依照(zhao)原理與不同槍(qiang)(qiang)(qiang)枝(zhi)的(de)機械設計方式有分(fen)(fen)為(wei)四種(zhong)(zhong)(zhong)(zhong)五類：第(di)一種(zhong)(zhong)(zhong)(zhong)是(shi)依賴活(huo)(huo)塞(sai)原理進(jin)(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)機運作的(de)方式，亦即(ji)透過導流使氣(qi)(qi)(qi)體推(tui)(tui)動(dong)(dong)(dong)活(huo)(huo)塞(sai)，活(huo)(huo)塞(sai)連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機，透過這一串(chuan)的(de)程序完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)動(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)運作。然(ran)而(er)活(huo)(huo)塞(sai)的(de)運作以(yi)行(xing)(xing)程為(wei)主，以(yi)行(xing)(xing)程移動(dong)(dong)(dong)距離的(de)長短劃(hua)分(fen)(fen)，而(er)非(fei)以(yi)活(huo)(huo)塞(sai)的(de)重量或者大(da)小(xiao)劃(hua)分(fen)(fen)。第(di)二種(zhong)(zhong)(zhong)(zhong)是(shi)利用“收集”子彈的(de)高(gao)壓氣(qi)(qi)(qi)之后再導流進(jin)(jin)入汽缸推(tui)(tui)動(dong)(dong)(dong)活(huo)(huo)塞(sai)或整個(ge)槍(qiang)(qiang)(qiang)管(guan)(guan)連動(dong)(dong)(dong)到(dao)槍(qiang)(qiang)(qiang)機進(jin)(jin)行(xing)(xing)完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)動(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)運作。第(di)三(san)種(zhong)(zhong)(zhong)(zhong)是(shi)利用第(di)二種(zhong)(zhong)(zhong)(zhong)“收集”氣(qi)(qi)(qi)體的(de)原理進(jin)(jin)行(xing)(xing)推(tui)(tui)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管(guan)(guan)連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)動(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)運作。后一種(zhong)(zhong)(zhong)(zhong)是(shi)經(jing)由氣(qi)(qi)(qi)導管(guan)(guan)導流氣(qi)(qi)(qi)體向后“吹(chui)送”槍(qiang)(qiang)(qiang)機完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)動(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)運作。因此我(wo)們(men)大(da)約可以(yi)分(fen)(fen)為(wei)：短行(xing)(xing)程活(huo)(huo)塞(sai)傳動(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程活(huo)(huo)塞(sai)傳動(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)(qi)井集氣(qi)(qi)(qi)操(cao)(cao)作（Gas trap）。槍(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直噴式氣(qi)(qi)(qi)動(dong)(dong)(dong)操(cao)(cao)作（Direct impingement；也稱為(wei)Direct Gas Action）。
