Description
Product Overview
The HK MR556A1 is a premium civilian AR-pattern rifle built as a direct descendant of the HK416. It uses HK’s proprietary gas piston system with a solid operating pusher rod to keep fouling and waste gases out of the receiver area, helping provide reliable operation with match-capable accuracy potential. The 16.5-inch cold hammer forged, non-chrome-lined barrel and enhanced two-stage trigger support consistent shot-to-shot performance with 5.56 NATO ammunition and most quality .223 Remington loads.
Key Features
- HK proprietary gas piston operation with a solid operating rod for cleaner cycling
- Ambidextrous manual safety selector for left- and right-handed use
- Rail platform designed for mounting common optics (rail system may vary by package)
- Enhanced two-stage trigger for a more precise break
- 16.5-inch cold hammer forged barrel with unlined bore for accuracy-focused performance
If you want an AR-pattern rifle built around HK416-style reliability and match-oriented components, the MR556A1 is engineered for that role.

One of the best and...
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...
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.
