Why Choose the Type 2 (Double Ridge) Design?

The Type 2 Tactile Lock-Plate features two raised ridges spaced to be instantly distinguishable by touch. This pattern allows shooters to differentiate between ammunition types or specific loadouts simply by feel — ideal for professional, defensive, and competition shooters who manage multiple calibers or magazine load configurations.

Practical Benefits:

  • Improved Grip: Raised texture offers a better hold during reloads or mag changes, even with gloves or in wet environments.

  • Enhanced Reload Speed: Gives the support hand a predictable reference point for positive, repeatable mag indexing.

  • Consistent Ergonomics: Keeps magazine shape standardized while improving tactile feedback.

  • Durable & Lightweight: Polymer construction resists impact, oil, and temperature extremes without adding unnecessary weight.


Compatibility & Fitment Notes

  • Fits all PMAG GEN M3 AR/M4 10/20/30-round magazines and PMAG GEN M3 300 BLK versions.

  • Not compatible with older PMAG GEN 1 or GEN 2 magazines (different floor plate geometry).

  • Works seamlessly with factory PMAG floor plates — no tools or permanent changes required.

  • Designed to maintain full compatibility with standard mag pouches, chest rigs, and carriers.


Easy Installation Instructions

  1. Ensure all magazines are unloaded and safe to handle.

  2. Press the floor plate release button on the PMAG and slide off the existing lock plate.

  3. Slide the new MAG804-BLK Tactile Lock-Plate into position until it locks securely.

This upgrade installs in seconds and can be reversed at any time without damaging the magazine.

  • Competitive Shooters: Improve speed and confidence during timed reloads.

  • Defensive Carriers: Maintain control and awareness in low-light or high-stress conditions.
