A direct descendent of the HK416, the MR556A1 is a semi-automatic rifle developed by Heckler & Koch as a premium level commercial/civilian firearm with match rifle capability. Like the HK416, the MR556A1 is a major product improvement over conventional AR-type carbines and rifles.

The MR556A1 uses the HK proprietary gas piston operating system, employing a piston and a solid operating “pusher” rod in place of the gas tube normally found in AR15/M16/M4-style firearms.

This method of operation virtually eliminates malfunctions that are common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area. This is the same key feature critical to the success of the HK416 rifles used by leading military and law enforcement customers.

The MR556A1 is produced in the USA using American and German made components. The MR556A1 uses many of the same assemblies and accessories originally developed for the HK416.

Like the famous HK416, the MR556A1 uses a German-made barrel produced by Heckler & Koch’s famous cold hammer forging process. The highest quality steel is used in this unique manufacturing process producing a barrel that provides superior accuracy and long service life.

But unlike the HK416, the MR556A1 does not use a chrome-lined barrel. Chrome-lining can sometimes mask bore imperfections and negatively affect accuracy. For the new series of Heckler & Koch semi-automatic MR rifles, HK designers and engineers believe best accuracy comes with an unlined bore.

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 adds significantly 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.

Designed to function with a wide variety of high quality 5.56 x 45 mm ammunition, the MR556A1 uses a C.I.P. dimensioned chamber (a chamber with dimensions specified by the Commission Internationale Permanente).The MR556A1 also functions reliably 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 leverages the relative strengths of two continents to make the preeminent AR-type firearm, combining the designs innovations of the USA and Germany into one new product.

what can i say, it is expensive but totally worth it, i wish HK not mess with the bolt carrier( i know is to prevent full auto employment)and pls for the price they need to give you at least two of that beautiful magazines, it shots great just put 100 rounds without really zero the sights at 50 yards and the group is 1and half inch from standing and dime size from supported prone, i will take it to a proper range to see what can do with a proper zero, as well with eo-tech. BUDS as usual super professional, yes maybe 200 usd more expensive that what other sites offers, but they don't lie to you and when they tell you is in stock, it really is and 3 days later i have it at the FFL, instead other IMPACTG... sites who have you in backorder for "couple of weeks" (more like 47 days until i cancelled) so great job BUDS from now on you're my first choice for any online gun related buy.

Thanks to Buds for the great service and prompt shipping. Buds layaway program can be a huge help sometime, and it is the easiest system to use. I always check Buds 1st for just about all my firearm needs. As for my new MR556A1, well its almost mind blowing in every way. Function, operation, and the quality of this rifle is head and shoulders above every other AR platform rifle i have ever shot/held. All you have to do is hold this rifle to realize how special this weapon is. As always, BUDS GETS 5 STARS!!!

I just purchased this 3 weeks ago. It took until yesterday to receive it, but what a beauty. The fit/finish is unmatched. I'm taking it to the range this weekend. I'm so excited!

It arrived in excellent condition with all the parts and accessories. This is one solid, well built firearm.
