Born from the SOCOM PDW solicitation, the 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 18.75" in overall length, the PDX delivers groundbreaking power and performance in a subcompact platform.

At the heart of the PDXtrade; is our Maxim SCWtrade; 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 PDXtrade; comes equipped with Maxim's HATEBRAKE muzzle booster. This patent-pending device significantly reduces recoil, decreases the flash signature, pushes gasses and concussion waves downrange away from the operator, and improves overall performance.

  • Maxim Defense HATEBRAKE muzzle booster
