The M4/M15 Lite Rail features our patented “Bolt-Up System” which provides modern flat-top upper receivers with a continuous, uninterrupted upper rail platform and allows for simplified alignment to the host weapon upper receiver. The battle proven “Bolt-Up System” is also used on the renowned DD RIS II (selected by SOCOM for the SOPMOD II program). Every component of the M4/MR15 Lite Rail has been meticulously assessed, thoroughly shot and tested, improved upon, and manufactured tough enough to become the new bench-mark in AR rail systems. The M4/M15 Lite Rail is specifically designed for those who demand peak performance and ease of use.
The Lite Rail is a 1-piece, free float handguard featuring an uninterrupted upper rail platform. Installation requires the removal stock barrel nut and installation of the included "Bolt-Up System" barrel nut, this requires the use of a barrel nut wrench. All rails are CNC machined to 1913 Military Specifications.
