The US Army’s new sniper rifle will be rolled out later this year

WHEN you combine the skill of US soldiers with this new mighty sniper rifle, it means very bad news for those foolish enough to take on the United States. Army squads’ designated marksmen have been using the M110A1 7.62mm semiautomatic sniper rifle — but threats have evolved and US soldiers deserve the best rifle for the job. 

Enemy body armour is one of these evolving challenges. Russian-made advanced armour increasingly protects US adversaries. In war zones, US boots on the ground have had to contend with terrorist group ISIS protected by armour — and by ever stronger armour. 

US soldiers need a sniper rifle that they can always rely on to penetrate these types of strong armour and stop the threat. Once the Army announced that it was on the hunt for an upgrade, there was an intense competition to become the new sniper rifle. In 2016, the Army selected Heckler & Koch’s 7.62mm rifle based on their G28, with specific modifications tailored to meet the military’s requirements. And it is this compact semiautomatic sniper system that will be the new Squad Designated Marksman Rifle. (SDMR) Recently, the Army confirmed that this new, powerful sniper rifle should be in soldiers’ hands this year.

 WHAT’S THE CHANGE? The modified HK G28 will replace the Army’s current SDMR, the M110 SASS 7.62 compact sniper rifle. The last significant change was in 2010 when the Army aimed to standardise sniper rifles in use and introduced the M110 to replace models like the M14 (modified Remington 700). For starters, this will be a harder-hitting rifle than the rifle it replaces. The goal is to provide infantry soldiers with an upgraded, deadly capability. As well as providing better penetration of enemy forces’ armour, it is expected to be lighter, shorter, easier to carry and more ergonomic to use.

(Heckler & Koch)Source:Supplied G28 CLUES The new Army sniper rifle continues to be shrouded in mystery. Even when the Army announced it chose Heckler & Koch for the new weapon, the company kept quiet. No details emerged immediately from the Army either. Eventually, it was confirmed that the SDMR would be a modified version of the G28 to meet the Army’s requirements … but the details of the new sniper rifle remain the subject of much speculation and curiosity. 

While the details have yet to be confirmed on how the rifle will be modified, we can look at the G28 to get an idea of what soldiers might expect. Familiar with the civilian semiautomatic competition rifle MR308? The G28 is Heckler & Koch’s military version. One of the military upgrades to the civilian rifle is the G28’s green and brown camouflage looks. The German Army has been using the G28. Designed to meet the needs of designated marksmen tackling current threats, the G28 fires the same 7.62mm ammunition as the M110. It remains to be revealed whether the cutting-edge hard-hitting ammo underway by the genii at Fort Benning, and elsewhere, will be integrated. SIZE The Army was looking for accuracy and reliability in a more compact package. According to Heckler & Koch’s announcement, it looks like the modified G28 will give soldiers a shorter and lighter rifle than the M110. 

The M110 weighs about 1.1kg more than the G28 — so this new modified US Army G28 could potentially be even lighter than 5.7kg. How much shorter will the new gas-powered sniper rifle be? The G28 is 96cm long, so that is about 6.3cm smaller than the M110. A FEW G28 FEATURES In terms of accessories, the G28 rifle incorporates the new Stanag 4694 NATO accessory rails and mounts and backward compatibility with MIL-STD-1913 rail. The G28 has a telescopic stock with an adjustable cheek rest. Suppressor needed for the job? This rifle has a “toolless” gas regulator. In terms of safety, Heckler & Koch has incorporated safety/cocking in every hammer position.

For example, if a lighter version is needed for a patrol or assault rifle purposes, then the approximately 635g lighter patrol variant can be used. There is also an “Over the Beach” capability available. Leveraging thermal and starlight imaging, the G28 is designed for fighting at night as well. For close quarters threats, the modified G28 should deliver enhanced accuracy and performance while being easier to use. ACCURACY The G28 is designed to provide accuracy of 1.5 MOA. What’s the maximum effective range?

 The company indicates high first round hit probability up to about 792 metres. ESCALATING THREAT OF ENEMY BODY ARMOR Body armour made by some overseas companies can be bought by terrorists for less than $AU385 — and some types can stop US Army M110 rifle rounds and other weapons like the M4s firing 5.56mm rounds. Some Russian-made body armour models worn by ISIS will resist multiple hits of 5.56 and 7.62 rounds. 

One smart proposal was to take a currently available sniper system and adapt it so it can use remarkable new munitions created at places like Fort Benning. These munitions have the potential to penetrate any of these super tough armour plates. Two new weapons to penetrate enemy body armour $AU57.1 million worth of new upgraded sniper rifles — possibly as many as 3643 — will soon be in soldiers hands’ this year if plans continue on track. In addition to the new sniper rifle, there may also be a new replacement for the M249 squad automatic weapon that fires 5.56m rounds.
