The Daniel Defense AR-15 Omega Rail is a 2-Piece, Free Float Handguard featuring an uninterrupted top rail platform, a detachable lower rail, a pair of QD sling swivel sockets, 6061-T6 Aircraft Grade Aluminum construction, and a Type III Hard Coat Anodized finish. Installation of the Omega Rail is simple and fast, with no permanent modifications to the host rifle necessary, nor intensive disassembly of the rifle's gas system or delta ring assembly required. Once the original polymer handguards have been removed, the Omega Rail is then secured in their place to the factory barrel nut with the supplied set of Allen Head screws. All of the handguard's rail interface surfaces are precision CNC-machined to military M1913 Picatinny Rail specifications for ease of use with rail-mounted tactical accessories. Includes 3 black santoprene ladder-style rail covers.
