Stern 001-Sd Mag-Add-Flare

The Stern Defense MAG-ADD Flare is a magwell funnel attachment engineered to speed up magazine changes during shooting sessions. Designed for use with Stern Defense conversion adapters on mil-spec forged lower receivers, this flared magwell guide helps you load rounds faster and more reliably when precision and speed matter. Whether you're running drills at the range or working through defensive scenarios, a properly sized magwell reduces fumbles and keeps your focus on the shot.

Built from black Delrin—a tough, durable polymer that resists wear and maintains consistent performance over time—the Stern Defense magwell is manufactured in the USA. Delrin's smooth, low-friction surface naturally guides magazines into the well, making the difference between a rushed reload and a smooth one. The flared design opens the magwell slightly wider at the top, giving your fingers more room to seat a magazine quickly and confidently.

If you're running a 9mm or .40 S&W conversion system with Stern Defense adapters on your AR platform lower, this magwell is a practical upgrade that fits cleanly into your setup without adding unnecessary bulk. The black finish blends with most builds and works equally well on the range or in duty applications.
