氣(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作依照原理與不同(tong)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)機械(xie)設計(ji)方(fang)式有分為(wei)四(si)種(zhong)五類：第一種(zhong)是(shi)依賴活塞(sai)(sai)原理進行(xing)(xing)槍(qiang)(qiang)(qiang)(qiang)(qiang)機運(yun)作的(de)方(fang)式，亦即透過導流使氣(qi)(qi)體(ti)推(tui)動(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)，活塞(sai)(sai)連動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機，透過這一串的(de)程(cheng)序完(wan)(wan)成(cheng)(cheng)(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作。然而活塞(sai)(sai)的(de)運(yun)作以(yi)(yi)(yi)行(xing)(xing)程(cheng)為(wei)主，以(yi)(yi)(yi)行(xing)(xing)程(cheng)移動(dong)(dong)(dong)(dong)(dong)(dong)距離(li)的(de)長短劃分，而非以(yi)(yi)(yi)活塞(sai)(sai)的(de)重量或者(zhe)大(da)(da)小劃分。第二(er)種(zhong)是(shi)利用(yong)“收(shou)集”子彈(dan)的(de)高(gao)壓(ya)氣(qi)(qi)之后再導流進入汽缸推(tui)動(dong)(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)或整個槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)(qiang)(qiang)機進行(xing)(xing)完(wan)(wan)成(cheng)(cheng)(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作。第三種(zhong)是(shi)利用(yong)第二(er)種(zhong)“收(shou)集”氣(qi)(qi)體(ti)的(de)原理進行(xing)(xing)推(tui)動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)管(guan)連動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)(qiang)機完(wan)(wan)成(cheng)(cheng)(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作。后一種(zhong)是(shi)經(jing)由(you)氣(qi)(qi)導管(guan)導流氣(qi)(qi)體(ti)向后“吹送(song)”槍(qiang)(qiang)(qiang)(qiang)(qiang)機完(wan)(wan)成(cheng)(cheng)(cheng)槍(qiang)(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)作。因此我們大(da)(da)約可以(yi)(yi)(yi)分為(wei)：短行(xing)(xing)程(cheng)活塞(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程(cheng)活塞(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣(qi)(qi)井集氣(qi)(qi)操(cao)作（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)(qiang)口增壓(ya)器（Muzzle booster）。直噴式氣(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作（Direct impingement；也稱為(wei)Direct Gas Action）。
