Product Description
The Haga Defense HK MP5 Buffer Tube Assembly adds a mil-spec AR-15 buffer tube to the rear of HK MP5 platforms, opening up the full universe of AR-15 stocks and braces. This complete aluminum assembly includes the end plate, castle nut, and buffer tube so you can install it and immediately run your favorite AR-style stock or brace.
Machined entirely from aluminum, the assembly gives you a solid, durable interface that replaces the factory rear configuration with a standard mil-spec buffer tube. No more being limited to proprietary HK stocks—pick the length of pull, cheek height, and style that fits you best.
This assembly is part of the modular HDA3 system. If you ever want a different setup later, you can simply remove the buffer tube and swap in a 1913 end plate or an HDA3 stock/brace—no other changes needed.
