The Daniel Defense DDM4 PDW SBR (300 Blackout) is a short-barreled rifle built for compact performance, tactical versatility & suppressed operation. Its 7-inch cold hammer-forged, chrome-moly barrel with a 1:7 twist and linear compensator keeps subsonic rounds subsonic while directing muzzle blast forward. The pistol-length gas system & Maxim Defense CQB Gen 7 stock (brace on pistol variant) ensure smooth cycling in suppressed or unsuppressed configurations. A 6" MFR XL full-length M-LOK handguard, SLR MOD2 front handstop & GRIP‑N‑RIP ambidextrous charging handle provide modularity & ergonomic control for either-handed operation. Despite its compact 20.75" collapsed length and 5.7 lb unloaded weight, the PDW SBR delivers full-size AR performance. Built on durable 7075‑T6 aluminum upper & lower receivers, an M16-profile chrome-lined bolt carrier group, and Maxim enhanced buffer system, this SBR offers consistent reliability. Its ambidextrous selector & flared magazine well support rapid reloads, while its full-length Picatinny rail accepts optics and accessories. The DDM4 PDW SBR is a refined tool for personal defense, close-quarters use, and fun range shooting.
