The latest MR762 A4 represent an enhanced example of "no compromise" HK performance. Its short stroke gas piston operating system does not impart hot carbon fouling back into the action, allowing the weapon to run longer, with less maintenance and with less wear on internal components. Its adjustable gas regulator allows the operator to tune the action specifically for suppressed or unsuppressed operation. While fully ambidextrous controls, lighter weight and a slimmer profile make the new A4 easier to operate, manipulate and employ.

Caliber Dictionary
The Below Information Has Been Provided From Our Gun Caliber Dictionary And Is Meant For Informational Purposes Only. It Is Not Intended to Describe The Unique Specifications For This Ammunition.
The 7.62X51mm NATO cartridge was adopted by the U.S. in the M14 rifle in 1957. NATO adopted it in the same year, but in other platforms. The 7.62X51mm is essentially a shortened 30-06 case, allowing a more compact action and more compact ammunition at very minor cost in performance. A side benefit--which might not have been anticipated--is improved accuracy because of the greater efficiency of the shorter case. Although 7.62X51mm has been largely supplanted by the 5.56X45mm NATO cartridge in service rifles, it is still widely used by militaries around the world and remains a primary cartridge for light and medium machineguns. Due to its exceptional accuracy it is also a very common cartridge for military sniping at ranges to a bit beyond 1000 yards. The civilian version, the 308 Winchester, was introduced in 1952 while the 7.62X51MM was still in the experimental stages. — Craig Boddington
