The new quad-stack magazine design was developed as part of Desert Tech’s NGSW submission, the company in turn developed the Quattro-15 lower which paired with the QuadMag-53 aims to increase capacity stock AR-15 upper receivers with an enlarged magazine well. The magazine well is windowed to minimise additional weight and the magazine is quad-stack, double-feed.

To celebrate the launch, Desert Tech shared a new video, explaining the origins of the idea and how the new lower and magazine work. Check it out below:
