The Daniel Defense DDM4 ISR MILSPEC+ is an integrally suppressed AR-15 platform optimized for the .300 AAC Blackout cartridge, blending superior performance with legal compliance. It features a 9-inch cold hammer-forged, chrome-lined S2W® barrel with a fluted profile and target crown, permanently attached to a stainless steel suppressor with 17-4PH monolithic baffles and high-temp Cerakote-C finish. With integral suppression, the system achieves a total barrel length of 16 inches without designation as an SBR. A pistol-length direct-impingement gas system ensures consistent cycling with both subsonic & supersonic rounds, relieving the user from re-zeroing for suppressed fire. Built on 7075-T6 aluminum upper & lower receivers with type III hardcoat anodizing and enhanced flared magwell, the DDM4 ISR MILSPEC+ incorporates a 15" MFR XL KeyMod handguard and full-length Picatinny rail for accessory compatibility. Controls are fully ambidextrous, including GRIP-N-RIP charging handle, safety selector, and flared magazine release. A glass-filled polymer stock and grip with soft-touch overmolding offer ergonomic comfort. At approximately 7.57 lbs, with overall length ranging from 31.5" to 34.75" (stock adjusted), it delivers tactical ergonomics and suppressed accuracy in a mission-ready package
