New Sniper System

Heckler & Koch Defense Inc. was awarded a contract worth up to $44.5 million from the U.S. Army for a new compact sniper rifle. The Compact Semi-Automatic Sniper System (CSASS) will provide the service with a small, lightweight, highly accurate weapon, addressing a critical need to replace older and heavier rifles currently in use.

Under terms of the award, HK Defense will produce up to 3,643 rifles. The new HK rifle is a lightweight variant of the 7.62-mm G28 in use by the German Army. The HK CSASS capitalizes on the proven G28 and HK417 designs, meeting the U.S. Army’s requirements for accuracy, reliability, size, and weight. Heckler & Koch will also provide spare parts, support, and training to the U.S. Army.

«This award represents another significant achievement for Heckler & Koch», said Wayne Weber, President of Heckler & Koch USA. «The HK CSASS rifle is a substantial upgrade over the U.S. Army’s current sniper rifles, enhancing accuracy and reliability while providing for a handier, more compact arm. It also confirms Heckler & Koch as a leader in providing small arms to the U.S. military».

According to Daniel Wasserbly, IHS Jane’s Defence Weekly correspondent, the CSASS will more effectively execute a broad spectrum of missions than the current M110. The CSASS will provide the following upgrades: improved reliability, improved accuracy, and improved ergonomics; reduced weight and length; advanced coatings; improved optics; reduced felt recoil; enhanced suppressor performance; enhanced modular rail capabilities; an improved bipod, trigger, pistol grip, and butt-stock.
