The DDM4ISR is Daniel Defense’s Integrally Suppressed Weapon System that is constructed to perform incredibly using .300 Blackout. This second version of the DDM4 integrally suppressed rifle is built around a 9-inch, cold hammer forged barrel. Using a standard pistol-length gas system and a fluted barrel along with a target crown, the DDM4ISR fits the bill for performance and versatility.
As you may already know because of the ISR in this DDM4ISR name, the suppressor is built into the system, so it is ready for plinking right out of the box. Daniel Defense went above and beyond to ensure this integrally suppressed rifle is tuned and optimized for both subsonic and supersonic projectiles. This unique Milspec+ finish is a combination between burnt bronze and FDE that’ll be sure to have heads turning!
This DDM4ISR is a Milspec+ finish. The Daniel Defense DDM4ISR also comes in Green and Black.
