氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)依(yi)照原理(li)與不(bu)同(tong)槍(qiang)枝的(de)(de)(de)機(ji)械設計(ji)方式有分(fen)為(wei)四種(zhong)五類：第一種(zhong)是(shi)(shi)依(yi)賴(lai)活(huo)(huo)(huo)塞原理(li)進(jin)行(xing)(xing)槍(qiang)機(ji)運(yun)作(zuo)(zuo)(zuo)的(de)(de)(de)方式，亦即透過導(dao)(dao)流使氣(qi)體推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)(huo)(huo)塞，活(huo)(huo)(huo)塞連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)機(ji)，透過這一串的(de)(de)(de)程(cheng)序完成槍(qiang)枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。然而活(huo)(huo)(huo)塞的(de)(de)(de)運(yun)作(zuo)(zuo)(zuo)以(yi)(yi)行(xing)(xing)程(cheng)為(wei)主，以(yi)(yi)行(xing)(xing)程(cheng)移動(dong)(dong)(dong)(dong)(dong)距離的(de)(de)(de)長(chang)短劃分(fen)，而非以(yi)(yi)活(huo)(huo)(huo)塞的(de)(de)(de)重(zhong)量或者大小劃分(fen)。第二種(zhong)是(shi)(shi)利(li)用“收集(ji)”子彈(dan)的(de)(de)(de)高壓氣(qi)之后再(zai)導(dao)(dao)流進(jin)入汽缸推(tui)動(dong)(dong)(dong)(dong)(dong)活(huo)(huo)(huo)塞或整個槍(qiang)管(guan)(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)到(dao)槍(qiang)機(ji)進(jin)行(xing)(xing)完成槍(qiang)枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。第三種(zhong)是(shi)(shi)利(li)用第二種(zhong)“收集(ji)”氣(qi)體的(de)(de)(de)原理(li)進(jin)行(xing)(xing)推(tui)動(dong)(dong)(dong)(dong)(dong)槍(qiang)管(guan)(guan)連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)機(ji)完成槍(qiang)枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。后一種(zhong)是(shi)(shi)經由氣(qi)導(dao)(dao)管(guan)(guan)導(dao)(dao)流氣(qi)體向后“吹送(song)”槍(qiang)機(ji)完成槍(qiang)枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)(zuo)。因此我們(men)大約可以(yi)(yi)分(fen)為(wei)：短行(xing)(xing)程(cheng)活(huo)(huo)(huo)塞傳動(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長(chang)行(xing)(xing)程(cheng)活(huo)(huo)(huo)塞傳動(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)井集(ji)氣(qi)操作(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)口增壓器（Muzzle booster）。直噴式氣(qi)動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)(zuo)（Direct impingement；也稱(cheng)為(wei)Direct Gas Action）。
