Overview

The Maxim Defense CQB Pistol PDW Brace represents the pinnacle of compact AR pistol design with an ultra-short 5.375-inch collapsed length. At 18.59 ounces, the Gen 6 system integrates a 7075 aluminum alloy construction with SB Tactical's pistol stabilizing brace component. The system includes Maxim's proprietary buffer with options for Standard, Heavy, or 9mm weight JP Silent Captured Springs, providing reliable cycling in an impossibly compact package.

The CQB extends from 5.375 inches collapsed through intermediate positions (6.875 inches first position, 8.375 inches second position) to 9.24 inches fully extended. One-hand operation is possible with the Maxim collapse lever, enabling rapid length adjustments. The brace easily installs on mil-spec AR15 lowers and is compatible with all Maxim Defense CQB series buffer systems. Found on the legendary DDM4 PDW, it represents the shortest PDW brace available.

While the CQB delivers unmatched compactness, the 18.59-ounce weight and approximately $399 price point position it as a premium solution. The integrated JP buffer system requires commitment to the Maxim ecosystem, but for shooters prioritizing absolute minimum length for vehicle use, covert carry, or ultra-compact builds, the Maxim CQB PDW brace is the industry standard for compact AR pistol performance.
