[edit] History

The CAWS - Close Assault Weapon System - programme started in the early 1980s in the United States. The main goal of this programme was to develop a new generation personal firearm, capable of firing high-impulse, multiple projectiles with effective range of 100-150 meters. Using multiple projectiles should increase the chances of hitting the target in combat. One of the teams entered in the CAWS race was Heckler & Koch Germany, coupled with Winchester Corp. USA. Heckler & Koch was responsible for developing a weapon, while Winchester was responsible for the development of new types of ammunition. Although tested by the US military, the CAWS was cancelled, and production, both military and civilian, has halted.

[edit] Technical Definitions

HK CAWS is a select-fire, smoothbore weapon, designed to fire special, high-pressure shotshells, loaded with tungsten buckshot or flechettes. HK CAWS utilised a patented recoil-operated action with a moving barrel and an additional, self-regulated gas assist system (used to help unlock breechblock from the barrel if low-power ammo is used). The main goal of this system was to decrease felt recoil down to a suitable level.

HK CAWS in appearance is somewhat similar to the HK G11 advanced assault rifle, being built in bull-pup configuration, with integral carrying handle. The charging handle is located under the carrying handle, at the top of the receiver, and is ambidextrous. The standard HK-style safety-switch/fire selector has 3 positions: Safe, Semi-auto and Full-auto. It had a rate of fire of approximately 240 shots per minute.
