Daniel Defense DDM4 PDW 300 Blackout SBR 7" CHF Barrel - 30 Rd

The Daniel Defense DDM4 PDW SBR is an ultra‑compact powerhouse designed for shooters who demand reliability, maneuverability, and performance in a short‑barreled platform. Built by Daniel Defense, this premium short‑barreled rifle combines battle‑proven AR‑15 engineering with a purpose‑built 7" cold hammer forged .300 Blackout barrel, making it exceptionally well‑suited for both subsonic and supersonic ammunition.

Compact enough for tight spaces yet powerful enough for serious defensive applications, the DDM4 PDW is built around a rugged 7075‑T6 aluminum receiver set and equipped with a Maxim Defense CQB Gen 7 stock and enhanced buffer system. This advanced buffer system allows the platform to run reliably whether suppressed or unsuppressed, delivering smooth cycling and dependable operation.

A 6" MFR XL M‑LOK handguard provides a lightweight and modular interface for accessories while maintaining a slim profile for improved handling. The included SLR M‑LOK MOD2 handstop enhances control and safety during rapid manipulation. Paired with Daniel Defense’s GRIP‑N‑RIP ambidextrous charging handle, this rifle offers intuitive operation for both right‑ and left‑handed shooters.

The linear compensator directs muzzle blast forward and away from the shooter, improving comfort in confined environments while maintaining compatibility with 5/8×24 threaded muzzle devices for customization.

Built with Daniel Defense’s renowned attention to detail—including HP/MPI‑tested bolt carrier groups, chrome‑lined barrels, and precision CNC machining—the DDM4 PDW SBR is engineered for durability, reliability, and consistent performance.

Whether configured for defensive use, suppressed shooting, or compact tactical applications, the DDM4 PDW delivers exceptional capability in one of the most compact .300 Blackout platforms available.
