Heckler & Koch has been awarded the US Army’s Compact Semi-Automatic Sniper System (CSASS) with a potential USD44.5 million initial contract, according to a 1 April announcement.

The German company’s US subsidiary bested seven other bids for the work, understood to be with its Heckler & Koch G28 (Gewehr-28) Designated Marksman Rifle, meant to supplement the army’s 7.62 mm M110 Semi-Automatic Sniper System (SASS) fleet.

Under the deal the army could order up to 3,643 CSASS units, after initial qualification and operational testing on 30 CSASS units.

According to the programme’s February 2014 presolicitation notice, the army wanted enough CSASSs “to match the current M110 Army Acquisition Objective” of no more than 3,643.

“The CSASS will more effectively execute a broad spectrum of missions” than the M110, that notice said. “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.”

According to Jane’s Infantry Weapons , the Heckler & Koch G28 is a development of the civilian MR308 competition rifle (also known as the Distinguished Match Rifle – DMR762). The G28 is in service with the German Bundeswehr.

Heckler – Koch HK G28 designated marksman / sniper rifle was born as a result of recent experiences, gained by Bundeswehr (German army) in Afghanistan. This rifle is intended to extend effective range of infantry fire against enemy personnel beyond capabilities of the standard issue 5,56mm NATO assault rifles and light machine guns. While maximum effective range of 5,56mm weapons is about 400 meters, the 7,62mm HK G28 designated marksman / sniper rifle can provide accurate fire to ranges of up to 600 meters and suppressive fire at ranges of up to 800 meters. It is to be used as a support weapon at squad level during foot patrols and other operations, where use of 7,62mm general purpose machine guns and heavier support weapons is unavailable or undesirable. The HK G28 rifle is already in service with German army units in Afghanistan.

HK G28 designated marksman / sniper rifle is based on the Heckler-Koch MR308 civilian competition rifle, which is, in turn, an adaptation of the HK 417 automatic military rifle. The HK G28 is said to have about 75% parts commonality with HK 417. According to the Heckler & Koch literature, every HK G28 rifle is guaranteed to deliver accuracy of 1.5 MOA or better for 10-round groups with standard issue ammunition.

Heckler – Koch HK G28 rifle is semi-automatic, gas operated weapon. It uses short-stroke gas piston system with 2 position gas regulator, which allows for effective and reliable use of standard or subsonic ammunition (latter with sound moderator / silencer). Barrel is locked by conventional AR-15-style rotary bolt. Upper receiver of HK G28 rifle is manufactured from steel, lower receiver is made of aluminum alloy. Feed is from detachable box magazines with 10- and 20-round capacity, made of translucent plastic. Barrel is free-floated inside handguards.

As of now, Heckler – Koch HK G28 designated marksman / sniper rifle is available in two configurations, which can be changed from one to another at the base. These are Standard configuration (with long forend, bipod, telescoping shoulder stock with adjustable cheek rest, and Schmidt & Bender PMII 3-20×50 daytime telescope sight with laser rangefinder installed on the top) and Patrol configuration (with shorter and lighter forend, simplified telescoping buttstock and Schmidt & Bender PMII 1-8×24 daytime telescope sight). Rifle is equipped with new STANAG 4694 NATO accessory rails (backward compatible with Mil-Std 1913 / Picatinny rails) on the top of receiver and on the forend.
