Heckler & Koch HK437

The HK437 in calibre .300 Blackout is another building block of the modular HK433 multi-calibre platform. The special weapon with automatic capability has been designed primarily for use in medium-range tactical applications by special military and police forces who utilise the most compact weapons to achieve the maximum effect on the target.


 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.
