Maxim Defense PDX U.R.G 300 AAC Blackout Upper 5.5 In Complete Upper

The Maxim Defense PDX U.R.G. 300 Blackout upper blends innovative engineering with rugged reliability, delivering an optimized personal defense weapon upper built around a Direct Impingement system and a 5.5 inch barrel for compact versatility. At the heart of this configuration is the newly invented Maxim HATEBRAKE muzzle booster, a patent-pending device installed under the handguard that significantly reduces recoil, decreases the flash signature, and pushes gases and concussion waves downrange away from the operator to improve overall execution in short-barrel pistols and rifles. The 14 inch overall length and a matte black finish underscore a purpose-built design that pairs with any Mil-Spec lower receiver, while the 4 lb weight and precise HK height rail contribute to a rigid, dependable upper with enhanced reliability and enhanced low-flash, low-sound signatures. Built from military-grade materials including 6Al-4V Titanium, 17-4 Stainless Steel, 7075 and 6061 Aluminum, the PDX U.R.G. also features an M-slot compatible handguard for modularity and a high-strength upper rail. This complete upper is tailored for shooters seeking controlled recoil, streamlined handling, and enhanced performance in a compact, .300 AAC Blackout platform.
