Maxim MDX 505 PDX Upper - 300 BLK (Black)

The NEW Maxim Defense PDX™ U.R.G is built to handle the fierce demands of the Tier 1 community and designed to install on any Mil-Spec lower receiver. With the PDX™ U.R.G, you dominate close quarter encounters and achieve maximum energy on target without sacrificing accuracy at distance. At just 14” in overall length and a 5.5” barrel, the PDX™ U.R.G. is the ultimate choice for when concealment and personal defense is non-negotiable.

The PDX™ U.R.G. is also equipped with newly invented Maxim 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 in short barrel pistols and rifles. The PDX U.R.G. uses a Direct Impingement system.
