Born from the SOCOM PDW solicitation, the Maxim Defense PDX™ U.R.G. is designed to handle the fierce demands of the Tier 1 community. The PDX™ U.R.G. dominates in close-quarter encounters and achieves maximum energy on target without sacrificing accuracy at distance. At just 14” in overall length, the PDX™ U.R.G. is the ultimate choice for when concealment and personal defense is non-negotiable.

At the heart of the PDX™ KIT is our Maxim SCW™ system. This patent-pending design cuts down the length of the stock to 4” and offers an integrated BCG with interchangeable buffer weights to give you the flexibility to maximize performance and versatility without sacrificing functionality or form.

The PDX™ KIT is also equipped with Maxim’s HATEBRAKE™ Muzzle Booster. This patent-pending device significantly reduces recoil, decreases the flash signature, pushes gasses and concussion waves downrange away from the operator improving overall execution. The PDX Kit uses a Direct Impingement system.

The PDX Kit comes with everything you need to turn your lower receiver into a Maxim Defense PDX.
