**The Maxim PDX U.R.G ships with your choice of a Standard Mil-Spec BCG to be used with most common M4 compatible lowers, or a PDX/SCW compatible BCG buffer and Spring. If you have any questions please contact Customer Services prior to placing your order.

The Maxim Defense PDXU.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 PDXU.R.G. is the ultimate choice for when concealment and personal defense is non-negotiable.

The PDXU.R.G. is also equipped with Maxim’s HATEBRAKEMuzzle 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.

    Dropped this bad boy on a SCW lower and that was a wrap. Works exactly as intended.
