The 6.8 SPC-chambered M468 rifle employed the same direct gas-impingement system as the M4. The result was a system that jetted hot gases directly into the rifle’s receiver, leading to potential stoppages if regular maintenance and cleaning protocols were overlooked. To enhance potential mechanical reliability, Barrett incorporated a short-stroke, piston-driven system that offers the potential for cleaner and cooler operation than one with direct gas-impingement. Barrett is still selling its limited stock of the M468 but only as an upper receiver kit and not as a complete rifle.〔(M468 16" Upper Kit )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Barrett REC7」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
