barrel blank 中文意思是什麼
barrel blank
解釋
槍管半成品-
It is therefore surprising that the proposed standard version of the xm8 was to be the carbine with a barrel only 318 mm long, from which fragmentation is only likely to occur at point - blank range, if at all
因此xm8投標標準中卡賓槍的槍管只有318毫米長十分令人驚訝,這個長度下碎片效果根本上只有在近距離射擊時才出現。
