AR-15 fans rejoiced with the introduction of the Law Tactical Gen 3-M folding-stock adapter, which allowed them to fold the buffer-tube extension along the side of the AR receiver for compact storage and transport. Now, with the Law Tactical Gen 3HK folding-stock adapter, users of any rifle equipped with Heckler & Koch's proprietary receiver extension can now take advantage of the same features. Each Law Tactical Gen 3HK folding-stock adapter is constructed from steel and features a durable DLC finish. The adapter can be used on the HK417, MR762, MR308 and the G28, as well as any other gun featuring the same receiver extension. 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.
