Daniel Defense Ddm4 Pdw 300Blk Pistol Fde 7 30Rd

The Daniel Defense DDM4 PDW in 300 Blackout is a purpose-built AR pistol engineered for shooters who need serious firepower in a compact package. With a 7-inch cold hammer-forged barrel and overall length of just 20.75 inches, this 300 BLK pistol excels at close-quarters work while remaining nimble enough for vehicle-based or home-defense scenarios. The subsonic-capable barrel, combined with a direct impingement system, runs reliably whether you're launching subsonic loads through a suppressor or pushing supersonic rounds downrange unsuppressed.

Every component is built to Daniel Defense's exacting Mil-Spec standards and manufactured in the USA. The upper and lower receivers are CNC-machined from 7075-T6 aluminum; the chrome-moly vanadium barrel is cold hammer-forged with a 1:7 twist and heavy phosphate coat; and the bolt carrier group is M16-profile with a properly staked gas key. The Maxim Defense CQB Pistol Brace provides the ergonomic adjustment needed for consistent aim, while the enhanced buffer system delivers reliable cycling in suppressed or unsuppressed fire. A linear compensator redirects muzzle blast forward, and the 5/8×24 threaded muzzle accepts a wide range of suppressors and muzzle devices.

The 6-inch MFR XL handguard features M-LOK attachment points and includes an SLR M-LOK MOD2 plain front handstop, giving you plenty of real estate for tactical accessories and a solid grip platform. The ambi GRIP-N-RIP charging handle works smoothly for both left- and right-hand shooters. It ships with a Magpul PMAG 30 AR 300 B Gen M3 magazine and a Daniel Defense full-latch impact plastic case.

Built for hunters suppressing game, home defenders who value maneuverability, and shooters who want an AR pistol with uncompromising reliability, the DDM4 PDW 300 Blackout delivers professional-grade performance in an ultra-compact platform.
