- description
The CM041J follows the MP5J — the Japanese Police pattern, distinguished by its retractable stock with a soft rubber butt pad for comfort. CYMA build it in metal under a Umarex licence, and this High Speed edition is geared for a brisker rate of fire while keeping the familiar MP5 handling.
What's on the outside
It wears the MP5J's rubber-padded retractable stock and classic MP5 furniture, with a tri-lug flash hider sitting on a 14mm-CCW threaded muzzle, ready for tracers, suppressors or other tri-lug devices.

Frequently asked questions

What sort of stock does this MP5J have?
It's the Japanese Police pattern stock: retractable, finished with a soft rubber butt pad for a more comfortable cheek and shoulder position.
What does "High Speed Edition" mean here?

Can I put a tracer or suppressor on the muzzle?
