HK437
        Convincing argument with a penetrating effect
      
Speaks fluently supersonic and subsonic - also at the same time.
The HK437 is available in 7 and 9 inch barrel lengths. With the appropriate gas adjustment, the HK437 can fire both supersonic and subsonic ammunition in mixed mode. The weapon shares the operating concept of the HK433. There is a choice of the push-button operating mode for users trained on HK416/AR-15 systems as well as paddle operating for trained G36/MP5 users.


Modular in application
For situation-oriented threat scenarios using ballistic protective helmets, we offer two other buttstock options. The first is our tactical helmet buttstock for use with ballistic helmets with a short protective visor. It features a detachable and height-adjustable cheek rest, and is also length-adjustable. It can be folded down to the right against the receiver as required. The second option is our dedicated helmet buttstock. It is geometrically designed for protective helmets that are equipped with a long protective visor. The helmet buttstock is also length-adjustable, but as a special feature, it can also be folded to the left or to the right. In this case, its end position is below the receiver. Pistol grip and trigger remain within easy reach.
