Military Specification Type III Hard Coat Anodized Finish
Made in the USA
Designed at the request of USSOCOM to provide M203 compatibility while still providing a free float rail system, the DANIEL-DEFENSE M4A1 RIS II Rail, 12.0, Black (DD-8001-BK) meets this requirement without the need for special tools.
The Rail Interface System II (RIS II) provides a rock-solid mounting surface via the patented "Bolt-Up System" and offers an uninterrupted top rail surface that runs from the rear of an A3 Flat-Top receiver to the end of the handguard. The "Bolt-Up System" is an extremely strong and proven design, tested thoroughly by USSOCOM, who ultimately selected it and the RIS II for the SOPMOD II Program.
Installation requires the removal of the factory barrel nut and replacing it with Daniel Defense's proprietary hardened steel barrel nut. This requires the use of the included Daniel Defense Barrel Nut Wrench. Six Grade-8 Mil-Spec fasteners are then used to secure the handguard tube to the upper receiver via a pair of matching aluminum Bolt-Up Plates.
All Daniel Defense rail systems carries a 100% satisfactions guarantee against defects in original materials and workmanship.
