Maxim Defense CQB PDW Pistol Brace


SKU: N/A Categories: , ,


Perfect for PDW pistols, the Maxim Defense Arm Brace gives you the adjustments needed to more comfortably shoot your AR pistol, and makes your pistol more compact for easier transport. Built on the same housing as our PDW stocks, you get the same durability and features. It’s also the perfect stock to run on your pistol while waiting on your Form 1 to clear. When that day comes, keep the same housing installed and simply swap out the arm brace for one of Maxim Defense’s butt stocks (not included). You can use your existing BCG.  Available with Standard Buffer & Spring, or JP Silent Spring. Silent Captured Springs are Maxim exclusives made by JP Rifles. By Eliminating the friction found in standard buffer setups, the JP Silent Captured Spring also allows for smoother action resulting in less sound as the bolt cycles.

Built in Sling Mounts, 7075 Aluminum Housing
The Maxim CQB features built in anti-rotational sling mounts on each side of the housing. Both the housing and the stock are made of 7075 aluminum for maximum strength to weight performance.

Length of pull preset & Steel Guide Rods
With the “grab and pull” operation of the Maxim Defense Arm Brace, you may want the brace to stop in the same position each time it’s deployed. Install the provided set screw and you can have consistent length of pull every time you expand the arm brace.
3/8” Black Nitride Steel guide rods for strength and stability.

Knurled collapse lever
One hand operation is possible with the Maxim collapse lever. The take down lever is knurled for positive gripping when hands are wet or wearing gloves.

“All Maxim Defense products are engineered and manufactured for durability. Extensive field testing with experienced operators ensure any weak points are extinguished, and all functionality has a purpose. You can trust that if a product is in our offerings, it is not built for safe queens.”
