Law Tactical’s Gen-3HK folding stock adapter is made specifically for use with Heckler & Koch’s proprietary receiver extension on the HK417, MR762, MR308, M110A1 and the G28.
To use, simply push the single-button release to fold the stock. To fire, move the stock back to its full-length configuration, and the adapter automatically locks into place.
