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 including the HK free-floating four-quadrant rail system.

The HK Free Floating Rail System (FFRS) handguard has four MIL-STD-1913 “Picatinny” rails and allows all current accessories, sights, lights, and aimers used on M4/M16-type arms to be fitted to the MR Series. The HK rail system can be 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 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.

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 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.

Excellent 223 AR a little pricey but definitely top of the line. Fed 600 rounds thru it over the weekend nothing but spectacular performance and as always Buds was second to none in customer satisfaction. Excellent layaway program, quick shipping and fast delivery thru local FFL

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.

I will review in 2 parts, customer service and product.

Customer Service. This is the second firearm I've purchased from Buds's. Search around, you probably won't find a price lower than Bud's, and if you do, it probably doesn't include shipping. Ordering is a breeze with the selected FFL feature. The rifle shipped within 24 hours and arrived 72 hours later, in perfect condition with all accessories and documentation. Another flawless Bud's transaction.

As for the weapon, I haven't fired it yet, only finger-banged it. I have experience with the 416, the 556 is every bit as fine a weapon. You cannot overstate the quality and attention to detail on this weapon. I will shoot this weapon using the excellent H&K diopter sight (I have an adjustment tool) with a Magpul AFG foregrip and Emags, no other bling required. Yes, it's heavy, but it's tight as a drum and rock solid. I have no doubt it will perform flawlessly. The only negative reviews you will read on this weapon is from those who can't or won't spend the money on a weapon they'd love to own. If you only have one 5.56 in your safe, it's this one - a combat proven tank of a weapon that will take whatever you can throw at it. Can't wait to hit the range. Overall a tremendously positive buying experience.

Excellent craftsmanship from hk once again! Excellent service from buds! Once you get used to the weight nicest ar platform I've fired.(I have colt, sig, and now hk) Only complaint is there is no ready-to-use sling mounts. Sig 516 gets the nod in that department.But if you can grab one there HOT and you know how that saying goes.purchase number 5-6 for me and 4 for my younger brother.Not sure if I can overpay anywhere again after finding buds!
