Maxim Defense MDX-505 PDX-SP .300 AAC BLK

Born from the SOCOM PDW solicitation, the NEW Maxim Defense PDX™ is designed to handle the fierce demands of the Tier 1 community. The PDX™ dominates close-quarter encounters and achieves maximum energy on target.

At just 471mm in overall length, the PDX™ delivers groundbreaking power and performance in a subcompact platform.

At the heart of the PDX™ is our Maxim SCW™ system. This patent-pending system cuts down the length of the stock to 4″. The integrated BCG with interchangeable buffer weights gives you maximum performance and versatility without sacrificing form and functionality. The PDX uses a Direct Impingement system.

The PDX™ comes equipped with Maxim’s HATEBRAKE™ muzzle booster. This patent-pending device significantly reduces recoil, decreases the flash signature, pushes gasses, and concussion wave downrange away from the operator, and improves overall performance.
