Transform Your Magazine Well Into A Close Ergonomic Foregrip
The FAB Defense MWG Mag-Well Grip is a useful accessory that will transform your AR-15 magazine well into a comfortable, close ergonomic foregrip for enhanced maneuverability and lower signature profile especially in CQB scenarios.
This unique tool attaches to the magazine well on the AR-15 and converts it to a more ergonomic vertical grip. By positioning the vertical grip so close to the firearms’ natural balance point target, it allows the operator to achieve faster transitions and ultimately improve weapon handling.

Works As A Flared & Extended Magazine Well Funnel
The FAB Defense MWG Mag-Well Grip is constructed from durable and lightweight fiberglass reinforced polymer adding no extra weight on the AR. Additionally the MWG functions as a magazine well funnel for an easier, faster, and more reliable magazine change.
Enhance your ability to maneuver in close-quarter combat zones with the FAB Defense Mag-Well Grip.
Features:
- Provides a tight and close hold for speed and maneuverability in CQB
- Prevents pressure on the magazine, reduce feeding-related malfunctions
- Functions as a flared and extended magazine well enhances reload speed, and allows keeping eye contact with target during reloading.
- Quick and easy installation, no gunsmith required
- Incorporates a serial number window
- Durable and lightweight fiberglass reinforced polymer construction
- Available in black, olive drab green, or flat dark earth
Compatibility:
- M16 5.56×45 lower receiver variants, without a flared magazine well.
- The MWG is not compatible with PMAG-GEN3
