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 18.75 inches in overall length, the PDX delivers groundbreaking power and performance in a subcompact platform. At the heart of the PDX is our newly developed Maxim SCW stock system. This patent-pending system cuts down the length of the stock to 4 inches. 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 is also equipped with newly invented Maxim 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 in short barrel pistols and rifles.
