氣動(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)依照原理(li)與(yu)不同槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)機械(xie)設計方式有分(fen)(fen)(fen)為四種(zhong)五類：第(di)一(yi)(yi)種(zhong)是(shi)(shi)依賴活塞(sai)(sai)(sai)原理(li)進(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)(qiang)機運作(zuo)的(de)(de)方式，亦即(ji)透過(guo)導(dao)流(liu)使氣體推動(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)，活塞(sai)(sai)(sai)連動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機，透過(guo)這一(yi)(yi)串的(de)(de)程(cheng)序完成(cheng)槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運作(zuo)。然(ran)而活塞(sai)(sai)(sai)的(de)(de)運作(zuo)以行(xing)(xing)程(cheng)為主，以行(xing)(xing)程(cheng)移動(dong)(dong)(dong)(dong)(dong)距離的(de)(de)長短劃分(fen)(fen)(fen)，而非以活塞(sai)(sai)(sai)的(de)(de)重量或者大(da)小劃分(fen)(fen)(fen)。第(di)二種(zhong)是(shi)(shi)利用“收(shou)集”子彈的(de)(de)高(gao)壓氣之后再導(dao)流(liu)進(jin)入汽缸推動(dong)(dong)(dong)(dong)(dong)活塞(sai)(sai)(sai)或整個(ge)槍(qiang)(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)(dong)到(dao)槍(qiang)(qiang)(qiang)(qiang)機進(jin)行(xing)(xing)完成(cheng)槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運作(zuo)。第(di)三(san)種(zhong)是(shi)(shi)利用第(di)二種(zhong)“收(shou)集”氣體的(de)(de)原理(li)進(jin)行(xing)(xing)推動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)(qiang)(qiang)機完成(cheng)槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運作(zuo)。后一(yi)(yi)種(zhong)是(shi)(shi)經由氣導(dao)管導(dao)流(liu)氣體向后“吹送”槍(qiang)(qiang)(qiang)(qiang)機完成(cheng)槍(qiang)(qiang)(qiang)(qiang)枝(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)動(dong)(dong)(dong)(dong)(dong)運作(zuo)。因此我們大(da)約可(ke)以分(fen)(fen)(fen)為：短行(xing)(xing)程(cheng)活塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)式（Short stroke）。長行(xing)(xing)程(cheng)活塞(sai)(sai)(sai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)式（Long stroke）。氣井集氣操(cao)作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)(qiang)口增(zeng)壓器（Muzzle booster）。直(zhi)噴式氣動(dong)(dong)(dong)(dong)(dong)操(cao)作(zuo)（Direct impingement；也稱為Direct Gas Action）。
