About this handguard
Daniel Defense M4A1 RIS II FSP Rail Assembly is a handguard for AR-15, 12.
Match the handguard to your barrel nut system and length to your gas block: a free-float handguard needs to cover the gas block or stop short of it. Check accessory mounting (M-LOK, KeyMod or Picatinny) against the lights and grips you plan to run.
Manufacturer details
The Daniel Defense Rail Interface System (RIS II) was designed at the request of the United States Special Operations Command (SOCOM) for the SOPMOD II program. SOCOM had a specific requirement for a free float M203 solution and Daniel Defense responded designing a revolutionary product to meet the government's need. The Daniel Defense RIS II allows the individual operator to free float the M203 grenade launcher without additional parts. As important special tools are not required to mount the M203 grenade launcher. This was accomplished by integrating all of the needed parts to free float the M203 into the rail itself. - KEY FEATURES - Aircraft Grade 6061-T6 Aluminum - Free-Floating Barrel Design For Increased Accuracy - Two-Piece Design for USSOCOM Allows For the Attachment of an M203 Grenade Launcher When Lower Rail Section is Removed. - Battle-Proven 6-Bolt Bolt-Up System Securely Attaches Handguard to the Upper Receiver - Grade 8 Military Specification Fasteners - Uninterrupted Upper Rail Platform & Mil-Spec 1913 Picatinny Rails - Mil-Spec Type III Hard Coat Anodized Finish (FDE) - Product Weight: 17.1 oz - Rail Length: 12.25 - Width: 2.23 - Height: 2.25 - Inside Diameter: 1.15 - Barrel Nut: Steel (For Patented Bolt-Up System) - Gas System: Carbine - Free Float: Yes - Continuous Upper Rail: Yes
