H&K MR762-A1 7.62 x 51mm .308, 16.5" barrel, No sights, 10 rounds
The Heckler & Koch MR 762 A1 rifle is chambered for 7.62 mm NATO. 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.
Using the HK-proprietary operating system,
the MR762A1 is gas operated and uses a piston and a solid operating
“pusher” rod in place of the common gas tube normally employed in
Pioneered by Heckler & Koch in the G36,
HK416, and HK417; this method virtually eliminates malfunctions common
to direct impingement gas systems since hot carbon fouling and waste
gases do not enter the receiver area. The MR762A1 stays cleaner,
reducing heat transfer to the bolt and bolt carrier, and drastically
reducing wear and tear on other critical components. The service life of
all parts is increased substantially.
The MR762A1 uses a barrel
produced by Heckler & Koch's famous cold hammer forging process.
This manufacturing process uses the highest quality steel, producing a
barrel that ensures superior accuracy, even after firing thousands of
rounds. The MR762A1 is produced at Heckler & Koch's American
manufacturing facilities from both American and German-made components.
The MR762A1 uses many of the assemblies and accessories originally
developed for the HK416/417 series including adjustable buttstocks,
ergonomic pistol grips, mechanical sights, and the HK free-floating
four-quadrant rail system/handguard. This MIL-STD-1913 “Picatinny” type
rail system allows all current accessories, sights, lights, and aimers
used on M4/M16-type weapons to be fitted to the MR series. The HK rail
system can be removed without special tools by the user and ensures 100%
return to zero when reinstalled.
Ambidextrous operating controls are
standard on the MR762A1, including a convertible charging handle and an
ambidextrous selector lever. The MR762A1 uses the same 10- and 20-round
translucent polymer box magazines made for the HK417; a 5-round magazine
is also under development. MR762A1 rifles are well-suited for a variety
of applications including law enforcement tactical, police patrol,
general sporting, and hunting (a 5-round magazine is under development).
The MR762A1 was introduced in January 2012
