The heart of this PDW is its 7-inch .300 AAC Blackout barrel paired with a compact linear-type muzzle device and a threaded muzzle. The format keeps overall length minimal while retaining the caliber's performance from short barrels. The free-float Daniel Defense MFR XL 6.0 M-LOK handguard adds rigidity and accessory flexibility, with a T-marked top Picatinny rail for precise slot reference.
The factory-marked DDM4.PDW upper includes caliber marking "300" and an "A" forging mark on the receiver. Controls are marked SAFE/SEMI, and the bolt carrier bears the DD logo. A Daniel Defense ambidextrous-latch charging handle is installed, offering easy manipulation from either side.
A Maxim Defense PDW sliding brace with dual guide rods and a hook-and-loop strap delivers a compact, adjustable rear interface. The black polymer pistol grip features an aggressive texture for a solid hold.
The pistol uses a direct impingement operating system on the AR-15 platform, built on aluminum receivers with a matte black hardcoat anodized finish. It is configured for 30+1 capacity in .300 AAC Blackout and ships without sights, letting the buyer configure the top rail to preference.
