HECKLER & KOCH HK417

The Heckler & Koch HK417 is a battle rifle and designated marksman rifle. It is designed and manufactured by Heckler & Koch in Germany.  Being the larger caliber version of the Heckler & Koch HK416, and chambered for the 7.62×51mm NATO rifle cartridge, it is intended for use where the penetrative power, stopping power, and range of the 5.56×45mm NATO HK416 would otherwise be insufficient. The HK417 is gas-operated, has a rotating bolt and is capable of selective fire.  The HK417 has been adopted for service by a number of armed forces, special forces, and police organizations throughout the world, including the Bundeswehr, United States Joint Special Operations Command, the United States Army, Russian Spetsnaz forces such as FSB Alpha Group, and others.  The HK417 is similar in internal design to the HK416, although the receiver and working parts are enlarged to suit the larger 7.62×51mm cartridge. The bolt is a seven-lug rotating type, which sits in a bolt carrier and operates in a forged alloy receiver resembling those of the Stoner-designed AR-10, AR-15 and M16 rifles.  Like the HK416, the HK417 is gas-operated with a short-stroke piston design similar to that of the Heckler & Koch G36. The short-stroke piston may be more reliable than the original direct impingement operation of the AR-15 design because, unlike these weapons, it does not vent propellant gases directly into the receiver, which deposits carbon fouling onto the bolt mechanism as well as heating it up. The early HK417 prototype used 20-round magazines from the Heckler & Koch G3 rifle family, which did not feature a bolt hold-open device. Later prototypes, however, switched to a polymer magazine with bolt hold-open. The magazine resembles an enlarged version of the G36's transparent magazine, except without the pins for holding more than one magazine together.

G28 | A DMR-System – far more than just another rifle with a scope The G28 is a military version of the civilian semi automatic competition rifle MR308. Deployed in the established 7.62 x 51 calibre, the “Designated Marksman Rifle” (DMR) ensures accuracy of 1.5 MOA whilst enabling a full night fighting capability.  Providing a maximum effective range and a high first round hit probability up to 600 meters, the HK241 will also allow suppressive fire against man size targets accurately up to 800 meters.  With its green brown tone, the G28 offers a camouflage color scheme that is being accepted around the world. An additional conversion kit supports user and mission specific requirements where the G28 can be configured to a Patrol version and be used as an Assault rifle.
