HK MR762A1 LRP III Semi-Automatic Rifle 7.62 NATO 16.5" Barrel (1)-10Rd & (1)-20Rd Magazines Vortex Viper PSTII Optic Included Green Furniture Black Finish
Taking an essentially standard MR762A1 (caliber 7.62 x 51 mm NATO) semi-automatic rifle, Heckler & Koch USA turns it into a more effective precision rifle by an astute addition of the right optics and accessories. A Vortex Viper PSTII 3-15×44 FFP MRAD, HK G28 adjustable cheekpiece buttstock, and LaRue Tactical BRM-S bipod are the primary add-ons that make the MR762A1 Long Rifle Package (LRP) more than a sum of parts.
Like its 5.56 mm counterpart, the MR762A1 is a direct descendent of the HK416/417 series, only in a semi-automatic rifle configuration developed for civilian users. It is assembled in the USA using US and German-made components and uses many of the same parts and assemblies developed for the legendary HK416 and 417.
The MR762A1 uses a proprietary HK short-stroke gas piston in place of the direct-gas-impingement system found on lesser AR15-style rifles that propels exhaust gas into the upper receiver to operate the action. In the “closed” HK piston system, exhaust gasses never enter the receiver, which means the HK runs cooler, cleaner and more reliably. And when adverse conditions, like dust, sand and mud are introduced, the advantage of the HK system becomes even more drastic. That is why so many of the world’s elite military and law-enforcement customers have absolute trust in their HKs.
The MR762A1 has a cold hammer forged barrel made from the highest quality cannon-grade steel, producing a barrel that ensures superior accuracy, even after firing thousands of rounds. And while the material and cold hammer forging process themselves greatly enhance durability, HK’s processes include many additional steps not taken by other manufacturers to produce superior accuracy and service life, ensuring performance well beyond “mil-spec.”

particular item.
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.
