Let’s Talk About Choate Tool Hk Mp-5 Housing & Tube
The Choate Tool Hk Mp-5 Housing & Tube is designed as an all-metal end cap that fits into the back of the receiver, securing the trigger group and offering an M-4 housing attachment point. This product directly addresses the need to modernize or modify the classic HK MP5K platform with AR-15 style stock options. Choate Tool aims to provide a robust solution for those seeking to adapt their MP5K or compatible firearms with greater modularity.
I had been looking for a way to add a more modern, adjustable stock to my MKE Z-5K pistol, and the common adapters seemed flimsy or not quite up to the task. This Choate Tool offering appeared to be a solid, all-metal solution, giving me the confidence I needed for serious range use.
Upon unboxing, the Choate Tool Hk Mp-5 Housing & Tube immediately impressed me with its heft and solid feel. The all-metal construction exuded quality, and the threads for the AR-15 buffer tube were cleanly cut and looked durable. It felt like a component built to withstand serious use.
Compared to other adapters I’ve seen online, often made of polymer or less substantial metal, the Choate Tool option inspired significantly more confidence. I almost went with a cheaper polymer adapter, but the potential for breakage under heavy recoil or stress swayed me to invest in this more robust option. I wanted something that would hold up, and this looked the part.
My first impression was one of excited anticipation. This seemed like the perfect solution to modernize my MP5K clone without compromising the integrity of the firearm. I was eager to install it and see how it performed.

First Use Experience
I tested the Choate Tool Hk Mp-5 Housing & Tube at my local outdoor shooting range. The weather was sunny, and the temperature was in the mid-70s, perfect for a comfortable shooting session. I ran several magazines through the Z-5K with the new stock installed.
The setup performed flawlessly. Recoil was managed effectively with the adjustable stock and the solid connection of the Choate Tool adapter. There were no unexpected issues or malfunctions.
Installation was straightforward, requiring only the removal of the original end cap and the push pins, and reassembly with the Choate Tool housing. I did have to use a rubber mallet to tap it into place, ensuring a snug fit. After that, it was rock solid.
Extended Use & Reliability
After several range sessions and a few hundred rounds fired, the Choate Tool Hk Mp-5 Housing & Tube has proven its durability and reliability. There are no signs of wear or loosening of the adapter. It remains as solid as the day I installed it.
