M4/M15 DD Lite Rail 4inch. The innovative Lite Rail 4.0 gives the weapon system an uninterrupted upper rail platform and also allows the Armorer to install the rail system with simplified alignment to the upper receiver. This kit is the lightest rail system available, and it also provide features that no other rail system possesses.
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.
