The 7 inch chrome-moly-vanadium barrel is cold hammer forged with Daniel Defense’s S2W profile and a 1:7 twist, optimizing it for .300 AAC Blackout. It is threaded 5/8x24 and paired with a pistol-length gas system to support the cartridge’s typical use cases.
The factory linear compensator has been replaced with a compact two-port muzzle brake/compensator. A low-profile M-LOK handstop is installed at the 6 o’clock position to aid indexing while keeping the front end streamlined.
The free-floated Daniel Defense MFR XL 6.0 M-LOK handguard provides M-LOK slots at 3, 6, and 9 o’clock and a full-length Picatinny top rail with T-marks. The right side of the receiver is marked “DDM4 PDW,” the upper is marked “300,” and the handguard is marked “MFR XL 6.0 M.”
The tan-finished receiver set is 7075-T6 aluminum. Controls include a manual safety selector and an ambidextrous charging handle. The pistol wears a Maxim Defense PDW-style brace in tan with dual guide rods and a black textured pistol grip.
Capacity is 30+1. This example includes three 30-round magazines (Hexmag and Magpul PMAG window variants), and it ships in the original black hard case.
