Maxim Defense PDX .300 AAC 5.5 inch Complete Upper

Description

Product Overview

The Maxim Defense PDX U.R.G. is a compact 5.5 inch .300 AAC complete upper receiver group built for mil-spec lower compatibility and direct impingement operation. Engineered for close-quarter use, the PDX U.R.G. combines an HK-height rail, an M-slot handguard interface, and the Maxim HATEBRAKE muzzle booster to help reduce recoil and muzzle signature while directing gases and concussion effects downrange away from the operator.

Key Features

• Direct impingement operation matched to Maxim PDX U.R.G. configuration
• Maxim HATEBRAKE muzzle booster installed under the handguard to improve execution in short-barrel use

If you’re building a compact, mil-spec lower–compatible .300 AAC setup, the Maxim Defense PDX 5.5 inch complete upper delivers the core package in a single ready-to-install configuration.
