The intermediate distance weapon for Special Forces
The HK237 is an indirectly gas operated weapon with push rod drive in connection with a rotating bolt head having locking lugs, in caliber .300 Blackout/.300 Whisper for special ballistical operational scenarios. From the point of view of operational tactics, this intermediate caliber is used especially by police and military special units in connection with a suppressor in low noise close range fights against protected and unprotected targets. The strengths of this caliber are shown above all in urban confined spaces such as fighting in built up areas where the issue is maximum mobility and target effect at short ranges. These are both the fight against primary targets up to a distance of 150 meters and against secondary targets such as monitoring cameras, light sources, guard dogs, etc.
From a design point of view the HK237 in calibers .300 Blackout/.300 Whisper has been designed on the basis of the tried and proven G36 in caliber 5.56 mm NATO. An absolutely identical operating and field stripping drill as well as completely ambidextrous operation are thus ensured to the user for both caliber groups. No additional training will be required.
Depending on the customer’s requirement, caliber change will either be carried out by exchanging the complete upper receiver or by changing the barrel inside the weapons original receiver.
The HK237 is available in the barrel lengths 9” and 12.5”.
