Maxim Defense MDX 505 PDX 5.56 NATO Mil-Spec Complete Upper - 5.5" Urban Grey

The Maxim Defense PDX(TM) 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(TM) 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(TM) U.R.G. is the ultimate choice for when concealment and personal defense is non-negotiable. The PDX(TM) U.R.G. is also equipped with Maxim's HATEBRAKE(TM) 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 U.R.G. uses a Direct Impingement system.
