Maxim Defense MDX 505 PDX Mil-Spec Complete Upper - 5.5" 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.
