氣(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)(zuo)依照原理(li)與不同槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)機(ji)械設計方式(shi)(shi)有分(fen)為(wei)(wei)四(si)種五類：第一(yi)種是(shi)依賴活塞(sai)(sai)(sai)原理(li)進(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)運作(zuo)(zuo)(zuo)(zuo)的(de)(de)方式(shi)(shi)，亦即透過導(dao)流(liu)使氣(qi)(qi)體(ti)(ti)推(tui)動(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)，活塞(sai)(sai)(sai)連動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透過這一(yi)串的(de)(de)程(cheng)序完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)(zuo)(zuo)。然而活塞(sai)(sai)(sai)的(de)(de)運作(zuo)(zuo)(zuo)(zuo)以行(xing)(xing)程(cheng)為(wei)(wei)主，以行(xing)(xing)程(cheng)移動(dong)(dong)(dong)(dong)距離的(de)(de)長短劃分(fen)，而非以活塞(sai)(sai)(sai)的(de)(de)重量或者大小劃分(fen)。第二種是(shi)利用“收(shou)集(ji)”子彈(dan)的(de)(de)高壓氣(qi)(qi)之(zhi)后再導(dao)流(liu)進(jin)入汽(qi)缸(gang)推(tui)動(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)或整個(ge)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進(jin)行(xing)(xing)完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)(zuo)(zuo)。第三種是(shi)利用第二種“收(shou)集(ji)”氣(qi)(qi)體(ti)(ti)的(de)(de)原理(li)進(jin)行(xing)(xing)推(tui)動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)(zuo)(zuo)。后一(yi)種是(shi)經(jing)由氣(qi)(qi)導(dao)管導(dao)流(liu)氣(qi)(qi)體(ti)(ti)向后“吹送(song)”槍(qiang)(qiang)(qiang)機(ji)完成(cheng)槍(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)運作(zuo)(zuo)(zuo)(zuo)。因(yin)此我(wo)們(men)大約可以分(fen)為(wei)(wei)：短行(xing)(xing)程(cheng)活塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長行(xing)(xing)程(cheng)活塞(sai)(sai)(sai)傳動(dong)(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣(qi)(qi)井集(ji)氣(qi)(qi)操(cao)作(zuo)(zuo)(zuo)(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口(kou)增(zeng)壓器（Muzzle booster）。直噴(pen)式(shi)(shi)氣(qi)(qi)動(dong)(dong)(dong)(dong)操(cao)作(zuo)(zuo)(zuo)(zuo)（Direct impingement；也稱(cheng)為(wei)(wei)Direct Gas Action）。
