hk machine gun briefcase

The HK machine gun briefcase, officially known as the 

Heckler & Koch MP5K Operational Briefcase, is a covert weapon system designed for discreet carry and quick deployment. 

Here's a breakdown of its features and history:

Features

• Concealment: The briefcase is designed to resemble a standard briefcase, allowing for the discreet carrying of an MP5K submachine gun.
• Rapid Firing: The ingenious design allows the user to fire the MP5K directly from the briefcase, without needing to open it.
• Integrated Trigger: A trigger mechanism is built into the briefcase handle, connected via linkages to the MP5K's trigger.
• Specialized Briefcase: The case is constructed with durable materials, often featuring a plastic body molded over an aluminum frame with stainless steel clasps, according to The Armourers Bench.
• Internal Mount: A modified STANAG claw mount secures the MP5K within the briefcase.
• Shell Deflector: Spent casings are deflected down into the briefcase body, preventing them from interfering with firing and keeping them concealed.
• One-Hand Operation: The design allows the user to operate the weapon with one hand.
• Safety Mechanism: A built-in safety on the handle prevents accidental firing.

They meant to say the plastic plugs that you can shoot off.  They are pictured in the ziplock.
