Daniel Defense DDM4 PDW Compliant, 300 Blackout, 7" Barrel, No Magazine, No Brace, Black, Pistol The Daniel Defense DDM4 PDW is a compact 300 Blackout AR-style pistol built for home defense, personal protection and fun at the range. Its 7 inch cold hammer forged barrel keeps subsonic loads subsonic and still gives good ballistics with supersonic ammunition, and the pistol measures 20.75 inches overall in its shortest configuration. This listing is part number 02-088-22070-067, a black hard coat anodized compliant version shipped without a magazine or brace. It comes with a 6 inch MFR XL M-LOK rail and a Daniel Defense linear compensator in a Daniel Defense full-latch impact plastic case. A 5.7 lb, 300 Blackout pistol that fits where a full-size carbine will not. 7 Inch 300 Blackout Barrel Daniel Defense hammer forges its barrels in house from chrome moly vanadium steel. Cold hammer forging packs the steel tight around a mandrel, which gives long barrel life and consistent accuracy. Each barrel is chrome lined, Mil-Spec heavy phosphate coated and HP/MPI tested. The PDW barrel uses the S2W profile, Daniel Defense's proprietary heavy contour, with a 1:7 twist that stabilizes both heavy subsonic bullets and lighter supersonic loads. The muzzle is threaded 5/8x24 and wears a Daniel Defense linear compensator made of 17-4 PH stainless steel with a salt bath nitride finish. The linear comp pushes blast and noise forward, away from the shooter, which matters a lot on a barrel this short. The threads also let you swap in a different muzzle device or mount a suppressor, and 300 Blackout is one of the best calibers to run suppressed. Check your local laws before buying or using a suppressor. Compliant Configuration, Brace and Buffer This compliant model is listed by our distributor as shipping without a pistol brace and without a magazine, so it can be sold into states that restrict those items. Daniel Defense's standard DDM4 PDW pistol is shown in the photos with the Maxim Defense CQB Pistol Brace; on this compliant unit the buffer tube is bare as shipped. Check your state and local laws before you add any brace, stock or magazine. Everything else matches the standard PDW: the same 7 inch barrel, MFR XL 6.0 rail, linear compensator and controls. Daniel Defense sells a separate SBR model with the CQB Gen 7 stock for buyers who have completed the NFA process. Rail, Controls and Handling The MFR XL 6.0 handguard is CNC machined from 6061-T6 aluminum and Type III hard coat anodized. It has a continuous top rail and M-LOK slots for lights, lasers and grips. An SLR M-LOK MOD2 plain front handstop comes installed to keep your support hand behind the muzzle. The GRIP-N-RIP charging handle has independent latches on both sides, so left- and right-handed shooters can run the rifle the same way. The pistol length direct impingement gas system uses a low profile gas block machined from hardened 4140 steel. The upper and lower receivers are CNC machined from 7075-T6 aluminum and Type III hard coat anodized. The upper has indexing marks and M4 feed ramps, and the lower has an enhanced flared magazine well and a rear QD swivel attachment point. The bolt carrier group is M16 profile, Mil-Spec MP tested and chrome lined, with a properly staked gas key. Who the DDM4 PDW Is For The PDW makes sense if you want a defensive long gun that stores in a small case, rides in a vehicle or backpack, and is easy to move with inside a house. Shooters who already own a suppressor will like how quiet it is with subsonic 300 Blackout. If you want something with more barrel, look at the rest of our Daniel Defense firearms or other AR-style pistols.
