Heckler & Koch INC MR-556 30+1 5.56 NATO 16.5

**Mouse over image above to zoom any area, or click on image to zoom the entire image.

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.

One of the best and most reliable 5.56 that I have ever shot. It may weigh more than the AR, but far superior. H&K by far makes the best rifles.

Too bad they don't have user profiles here. But anyway 30+yr gun collector and 12+yr Buds and Team Buds customer. One of my favorite brands is HK I own just about every gun they sold since the 80's I own pre-ban Mp5's and G3's. Also G36, TG36, MR762, SP89, SP94,SP5,SP5K and most handguns again since the 80's my most recent HK pistol was a .45 tactical compact. I have 2 MR556's one is a MR556 416 clone built from a 416 parts kit the other I keep NIB for my collection, only HK guns I do not own is the UMP which I dislike and the MP7 which I love. Lets face it HK products are pretty expensive as are spare parts, also many parts are proprietary so be aware of this when buying any HK firearm. From the one I do shoot its has the best fit and finish of any AR in my collection (DD,LWRC, SIG or Colt etc) and its also the smoothest shooting out of all my AR's. Its heavier than your standard DI gun but the weight helps if your shooting for groups or accuracy etc. I shoot everything from steel to match ammo thru this gun and it eats everything no problem runs suppressed fine even though it has a self regulating gas piston system. It fits standard STANAG mags, hang grips and stocks but hand guards are proprietary if I am not mistaken. The one thing I like about this gun is that you can put the gun on safe even with the hammer down. So if you want a premium German made piston AR I highly recommend it. Some always ask if its worth the $3k+ I always say price or worth is subject to the individual. For me yes its worth it as you are NOT just paying for the name and that goes for every HK firearm nothing really compares.

I will keep this review simple. After shooting it a few times I have to say it is the best rifle I have ever owned. Fit and finish was flawless. It is very accurate and I have not had a malfunction of any kind, although I have only been to the range twice with it. Very happy with my purchase.

The HK MR556, civilian model to the HK416, is a fine weapon and built like a heavy tank. It is a bit heavy at 8 pounds empty and over 9 pounds loaded. Very accurate out of the box.and never jams. The short stroke piston system is a huge advancement over the direct impingement gas system of the M4/M16. It shoots cooler and cleaner. After 500 rounds, the bolt carrier group was as clean as when I started. I can see why the Special Ops guys like this rifle. It is indestructable , reliable, but too heavy for me. I much prefer my FN SCAR.

I bought a HK 556, I originally had it on my wish list, I was informed when they were available and I purchased it. No problems. I have purchased over a dozen firearms over the past four years with Buds and have never had a problem. You must inspect the firearm before accepting the transfer and know what you are buying, especially when you buy online and are not able to inspect the firearm. Be a smart consumer.
