Compact and easy to transport, the Daniel Defense DDM4 PDW is the kind of pistol you can rely on for home and personal defense…plus it’s a ton of fun to shoot.

Featuring an overall length of 20.75", the DDM4 PDW easily fits into a backpack for convenient transport. The DDM4 PDW comes equipped with the Maxim Defense CQB Pistol Brace, which gives you the adjustments needed to more comfortably shoot your AR pistol. This highly maneuverable pistol comes with a 6" MFR XL flat front rail for fast handling, accuracy, and reliability while also providing compatibility with a wide variety of accessories. The DDM4 PDW features M-LOK attachment points and an SLR M-LOK MOD2 Plain Front Handstop to help ensure a safe shooting experience. Also available as SBR with Maxim Defense CQB Gen 7 stock.

Soy de Puerto Rico y aun que llevo unos 34 años tirando con armas cortas, escopetas y rifles o carabinas no fue hasta hace unos 2 años que supe del calibre 300, me dedique a buscar información y me intereso tanto que adquirí esta bestia de destrucción es un arma de excelente tamaño muy cómoda para disparar aunque es un poco pesado se acomoda perfectamente a mi y le coloque una mira telescópica qué donde apunto es donde impacto en fin lo recomiendo 100% excelente arma.

So much fun to shoot and with a can even better. Would have gave 5 stars but it (and most of their AR platform's do as well) comes with a pretty bad trigger. I upgraded the trigger and now it is definitely 5 stars.

Amazing firearm shoots great operation is flawless I’d expect nothing less from Daniel Defense

Oh man what can I even say about this other than absolute perfection? 10/10 gun.

Solid AR platform shot 1 inch groups at 30 yards. Love the retractable arm brace. Trigger could be better.

Daniel Defense is producing the finest AR’s on the market. This one exceeds the already high level of quality I am accustomed to from DD.

If your on the fence and you have the money to afford it I would recommend it. Great weapon for home defense. If you can just find the ammo a case of it will cost you more than the gun itself.
