Born from the SOCOM PDW solicitation, the NEW Maxim Defense PDX SBR 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 sub compact platform.

At the heart of the PDX SBR is Maxim’s newly developed Maxim SCW stock 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 SBR 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.

Maxim Defense HATEBRAKE Muzzle Booster

A common problem in short barrel PDW’s with low-pressure cartridges is reliable cycling. Maxim Defense Hate Brake muzzle booster is designed to regulate firearm exhaust gases to ensure PDW’s cycle more reliably.

The primary design features include the redirection of the sound signature, decreasing the flash signature, significantly reducing recoil, and increasing accuracy.

The HATE BRAKE installs with a 3/8” drive socket from the front, enabling it to be installed under a handguard without removing the handguard. During installation, the HATE BRAKE locks into place with K-Taper, a patent-pending taper locking technology, replacing the need for proprietary tapered barrels. The external shape of the HATE BRAKE is designed to work with M-Slot compatible hand guards.
