氣動(dong)(dong)(dong)操(cao)作(zuo)依照(zhao)原理與不同(tong)槍(qiang)(qiang)(qiang)枝的(de)(de)(de)機(ji)械設計方式(shi)(shi)有分(fen)(fen)為四種(zhong)(zhong)五類：第一種(zhong)(zhong)是(shi)依賴活塞(sai)原理進(jin)行(xing)(xing)槍(qiang)(qiang)(qiang)機(ji)運作(zuo)的(de)(de)(de)方式(shi)(shi)，亦即(ji)透過(guo)導(dao)(dao)流使(shi)氣體推(tui)動(dong)(dong)(dong)活塞(sai)，活塞(sai)連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)，透過(guo)這(zhe)一串(chuan)的(de)(de)(de)程(cheng)(cheng)序(xu)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)運作(zuo)。然而活塞(sai)的(de)(de)(de)運作(zuo)以(yi)行(xing)(xing)程(cheng)(cheng)為主，以(yi)行(xing)(xing)程(cheng)(cheng)移動(dong)(dong)(dong)距離(li)的(de)(de)(de)長短劃分(fen)(fen)，而非(fei)以(yi)活塞(sai)的(de)(de)(de)重量或者大小(xiao)劃分(fen)(fen)。第二(er)種(zhong)(zhong)是(shi)利用“收集(ji)”子彈的(de)(de)(de)高壓氣之后再導(dao)(dao)流進(jin)入汽缸推(tui)動(dong)(dong)(dong)活塞(sai)或整個(ge)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)到槍(qiang)(qiang)(qiang)機(ji)進(jin)行(xing)(xing)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)運作(zuo)。第三種(zhong)(zhong)是(shi)利用第二(er)種(zhong)(zhong)“收集(ji)”氣體的(de)(de)(de)原理進(jin)行(xing)(xing)推(tui)動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)管連動(dong)(dong)(dong)槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)運作(zuo)。后一種(zhong)(zhong)是(shi)經由氣導(dao)(dao)管導(dao)(dao)流氣體向后“吹送”槍(qiang)(qiang)(qiang)機(ji)完(wan)成(cheng)槍(qiang)(qiang)(qiang)枝的(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)/半(ban)(ban)自(zi)(zi)動(dong)(dong)(dong)運作(zuo)。因此我們大約可以(yi)分(fen)(fen)為：短行(xing)(xing)程(cheng)(cheng)活塞(sai)傳(chuan)動(dong)(dong)(dong)式(shi)(shi)（Short stroke）。長行(xing)(xing)程(cheng)(cheng)活塞(sai)傳(chuan)動(dong)(dong)(dong)式(shi)(shi)（Long stroke）。氣井集(ji)氣操(cao)作(zuo)（Gas trap）。槍(qiang)(qiang)(qiang)口增壓器（Muzzle booster）。直噴式(shi)(shi)氣動(dong)(dong)(dong)操(cao)作(zuo)（Direct impingement；也稱(cheng)為Direct Gas Action）。
