氣動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)依(yi)照(zhao)原(yuan)理(li)與不同(tong)槍(qiang)枝(zhi)的(de)(de)(de)(de)(de)機械設計方(fang)式(shi)有分為(wei)(wei)四種五類：第(di)一種是依(yi)賴(lai)活(huo)塞原(yuan)理(li)進(jin)行(xing)(xing)槍(qiang)機運(yun)作(zuo)(zuo)的(de)(de)(de)(de)(de)方(fang)式(shi)，亦即透過導(dao)(dao)流使氣體推動(dong)(dong)(dong)(dong)(dong)活(huo)塞，活(huo)塞連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)機，透過這一串的(de)(de)(de)(de)(de)程序完成(cheng)槍(qiang)枝(zhi)的(de)(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。然(ran)而活(huo)塞的(de)(de)(de)(de)(de)運(yun)作(zuo)(zuo)以(yi)行(xing)(xing)程為(wei)(wei)主，以(yi)行(xing)(xing)程移動(dong)(dong)(dong)(dong)(dong)距離的(de)(de)(de)(de)(de)長(chang)短劃分，而非以(yi)活(huo)塞的(de)(de)(de)(de)(de)重量(liang)或(huo)者大小(xiao)劃分。第(di)二種是利用“收(shou)集”子彈的(de)(de)(de)(de)(de)高壓氣之后(hou)(hou)再導(dao)(dao)流進(jin)入汽缸推動(dong)(dong)(dong)(dong)(dong)活(huo)塞或(huo)整個槍(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)到槍(qiang)機進(jin)行(xing)(xing)完成(cheng)槍(qiang)枝(zhi)的(de)(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。第(di)三種是利用第(di)二種“收(shou)集”氣體的(de)(de)(de)(de)(de)原(yuan)理(li)進(jin)行(xing)(xing)推動(dong)(dong)(dong)(dong)(dong)槍(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)槍(qiang)機完成(cheng)槍(qiang)枝(zhi)的(de)(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。后(hou)(hou)一種是經(jing)由氣導(dao)(dao)管導(dao)(dao)流氣體向后(hou)(hou)“吹送”槍(qiang)機完成(cheng)槍(qiang)枝(zhi)的(de)(de)(de)(de)(de)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)/半(ban)自(zi)(zi)動(dong)(dong)(dong)(dong)(dong)運(yun)作(zuo)(zuo)。因此我們(men)大約可以(yi)分為(wei)(wei)：短行(xing)(xing)程活(huo)塞傳動(dong)(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)行(xing)(xing)程活(huo)塞傳動(dong)(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣井集氣操作(zuo)(zuo)（Gas trap）。槍(qiang)口(kou)增壓器（Muzzle booster）。直噴式(shi)氣動(dong)(dong)(dong)(dong)(dong)操作(zuo)(zuo)（Direct impingement；也稱為(wei)(wei)Direct Gas Action）。
