    Congratulations! You have just obtained the originl, classic 9mm muzzle suppressor designed for the Heckler & Koch MP5 submachine gun. While an older design, the MK-9K remains one of the most efficient 9mm subma- chine gun suppressors available anywhere. Before use, please take a few moments to read this instruction manual.
  • Page 5: Mounting On Weapons

    For mounting on other weapons, the sup- pressor can be special ordered to mount on a 1/2-28 threaded barrel. The MK-9K using the Tri-Lock 3-lug coupler must never be mounted on a 3-lug threaded barrel without a thread protector in place. Failure to observe this caution may result in misalignment.
