This is an adapter to attach the Gear Head Works style Tailhook to the HK MP5 A3-F retractable stock. This is not compatible with the K model. This adapter was inpsired by Flood's Tailhook adapter for MP5 A3 retractable stock (see video below).
* Trim off the excess material from the stock for clearance, as seen in Renders/picture5.png and Renders/picture6.png. Note you will be cutting into some metal.
* Cut the entire rubber butt pad off.
* Use the Adapter as a drill guide and drill and tap the holes in the back of the stock where the rubber butt pad use to be. There is a piece of metal in rear of the stock, as seen in Renders/picture3.png and Renders/picture7.png, so you will be threading metal holes for your bolts.
* Install the adapter to the end of the stock with the bolts.
