The Daniel Defense DDM4 ISR is an integrally suppressed rifle optimized for .300 Blackout. Its 9.00" cold hammer forged, fluted barrel with a target crown runs a pistol-length gas system, and the integral suppressor extends the barrel assembly to 16.00", so the rifle is not classified as a short-barreled rifle and needs only a single NFA tax stamp, for the suppressor.
With the suppressor built in, there is no mounting a can, checking alignment or re-zeroing between suppressed and unsuppressed fire, and the platform runs both subsonic and supersonic loads. The suppressor's outer tube wears a high-temperature Cerakote finish and its baffle core is user-serviceable for cleaning, while the MFR XL 15.0 handguard provides a continuous Picatinny top rail for optics and sights.
