The Daniel Defense DDM4ISR is an integrally suppressed .300 Blackout rifle that only requires the buyer to acquire a single tax stamp because the barrel/suppressor combination comes out to 16". The DDM4ISR is built on a pistol length direct impingement gas system due to its 9" barrel. The DDM4ISR removes all the complications usually associated with suppressor use like correct timing or re-zeroing optics for suppressed and unsuppressed fire. The baffle core can be easily removed for cleaning and general maintenance.

The Daniel Defense DDM4ISR uses the MFR XL fifteen inch modular handguard with a KeyMod attachment points and a full length top rail for the mounting of optics and NV/thermal devices. The pistol grip of DDM4V11 rifle is a proprietary Daniel Defense design with soft touch over molding and the 6-position buttstock features the same soft touch over molding at contact areas. Additionally the DDM4ISR ships with a Daniel Defense vertical grip for improved maneuverability and fire control.
