( LIVE ON GUN BROKER ) 2019 Heckler Koch MR556A1 & VP9 *2-GUN SET W/CUSTOM FITTED HK CASE*

Bryant Ridge's Analysis:
EXAMPLE AThe MR556A1 is a semi-automatic rifle developed by Heckler & Koch as a high-end commercial/civilian firearm with match rifle capabilities. It is a direct descendant of the HK416 and is a significant improvement over traditional AR-type carbines and rifles. The MR556A1 is a firearm that utilizes HK's exclusive gas piston operating system, which replaces the gas tube found in AR15/M16/M4-style firearms with a piston and a solid operating pusher rod. This innovative operational method virtually eliminates the malfunctions that are common in direct impingement gas systems due to the absence of hot carbon fouling and waste gases in the receiver area. This feature has been instrumental in the success of the HK416 rifles among the leading military and law enforcement customers.
The MR556A1 is produced in the USA using American and German-made components. It uses many of the same assemblies and accessories originally developed for the plate_number_1, including the HK free-floating four-quadrant rail system. The HK Free Floating Rail System (FFRS) handguard has four MIL-STD-1913 “Picatinny” rails, allowing all current accessories, sights, lights, and aimers used on M4/M16-type arms to fit the MR Series. The HK rail system can be easily installed and removed with simple tools and returns to zero when reinstalled.
The MR556A1 also has a Picantinny rail machined into the top of its upper receiver for mounting optics and mechanical sights. Unlike earlier prototypes, major subassemblies, including the MR556A1 upper receiver/barrel assembly, are fully interchangeable with other high-quality AR-style firearms. MR556A1 upper receiver kits can be used to retrofit competing legacy AR systems. Like the famous HK416, the MR556A1 uses a German-made barrel produced by Heckler & Koch’s famous cold hammer forging process. The manufacturing process uses the highest quality steel, producing a barrel that provides superior accuracy and long service life.
However, unlike the HK416, the MR556A1 does not use a chrome-lined barrel. Chrome-lining can mask bore imperfections and negatively affect accuracy. For the new series of Heckler & Koch semi-automatic MR rifles, HK designers and engineers believe that the best accuracy comes with an unlined bore. Used with the HK Free Floating Rail System, the barrel does not touch the handguard, ensuring the barrel is truly free-floating for maximum accuracy. The unchromed barrel has an internal profile of 6 lands and grooves with a 1 in 7 inch (178 mm) twist. It is also moderately “swagged” with a slightly smaller internal diameter at the muzzle end than the chamber end. This feature has a positive effect on bullet accuracy and velocity. The thick, heavy contour 16.5-inch MR556A1 barrel also contributes to its excellent accuracy.
A precise enhanced two-stage trigger significantly adds to the accuracy of the MR556A1, and an extended latch charging handle makes operating the rifle with a telescopic sight easier. The retractable buttstock can be locked into a solid, non-moving position by tightening an Allen screw in the bottom of the stock. Special target rifle takedown pins ensure the upper and lower receivers are firmly mated for accurate performance. The MR556A1 is capable of functioning with a diverse range of high-quality 5.56 x 45 mm ammunition, thanks to its C.I.P. dimensioned chamber. This chamber has dimensions specified by the Commission Internationale Permanente. Additionally, the MR556A1 has demonstrated reliable performance with most quality Caliber .223 Remington ammunition.
The MR556A1 is being produced with the same commitment to quality as German-made HK firearms. By using joint U.S./German manufacturing, Heckler & Koch combines the design innovations of the USA and Germany into one new product, making the preeminent AR-type firearm.
