The Daniel Defense M4A1 RIS II handguard is a 12.25 in, free-float, two-piece quad rail built from 6061-T6 aluminum with the multi-bolt Bolt-Up interface. It features T-marks on the top rail, patent reference, CAGE code marking, and the NSN 1005-01-547-2684. This configuration delivers a robust mounting platform while maintaining a free-floated barrel.
The 16.1 in cold-hammer-forged, threaded barrel is designed for durability and consistency. It is paired with an A2-type flash suppressor and operates via a direct impingement system. The bore condition and rifling are both rated excellent.
