總重空槍：38 公斤（83.78 磅）
三腳架：58 公斤（127.87 磅）
全長 1,650 公釐（64.96 英吋）
槍管長度 1,140 公釐（44.88 英吋）

白朗寧M2（M2 Machine Gun）機槍是美國槍械大師約翰•白朗寧在一次大戰後設計的重型機槍，
由於採用12.7×99公釐（0.5英吋）大口徑彈藥，因此又俗稱為50機槍。

M2型機槍最大有效射程2,000公尺，每分鐘射速大約500至600發子彈，能夠摧毀敵軍的車輛以及射殺步兵。
該機槍重38公斤（83.8磅），如果使用三腳架，其重量更逼近60公斤，因此大多數M2型機槍都被用作為
車載、直升機搭載武器，或是部署於火力陣地使用。

自1921年以來，M2型機槍已經生產了大約300萬挺，經歴了二次大戰、韓戰、越戰、波斯灣戰爭、2001年阿富汗戰爭、
伊拉克戰爭等戰役，除了增加快拆槍管外，原始設計幾乎沒做太大更動。除了美軍使用外，另有超過50個國家加以採用，
我國軍方也是M2機槍的使用國。

美國有句俗語：「東西沒有壞掉就不要修理它。」M2機槍也是如此，由於M2機槍具有射擊精度高，性能穩定，堅固耐用，
操作靈活等特性，深獲前線士兵喜愛與信任，美軍士兵還暱稱M2機槍為「乾媽」（Ma Deuce）。

今年美國陸軍已經說服國會提供資金，將陸軍裝備的全部45000挺M2HB式12.7毫米機槍升級到M2A1標準，此次升級可
使機槍的操作更加容易和安全。

將M2HB式機槍升級到M2A1標準包括在設計上進行改變。M2A1機槍具有固定的上部空間，這不僅使士兵在更換槍管之後
無需對機槍進行手動校準，而且也可減少士兵在更換槍管時暴露在敵方火力之下的時間。

14個月前，美國國防部已經開始升級6000挺M2機槍。M2A1機槍能夠快速更換槍管，每支槍管的重量為10.9千克，還可安裝
戰術導軌，以供加裝瞄準工具等附件。目前已有5080挺新型 M2A1 機槍正在生產中。

在41張圖槍機進彈撥桿滑槽有彈壳嚴重撞傷痕跡!?這QCB應該有發生膛炸之類的事情.
