“Mister Five-Five-Six” is finally here: the Heckler & Koch MR556-A1 — the civilian version of the HK416. Until now, this piston-driven powerhouse has only been available to the world’s most elite commandos. Well folks, it’s no longer vaporware for us civvies. They’re actually shipping to dealers and we just received our first unit (serial #500) yesterday. Upon inspection, I can tell you it was worth the wait!

Not unlike an Audi, BMW, or Mercedes saloon– the MR556-A1 is the fusion of high performance and subtle, elegant features. This is German engineering at its finest. Minute details include detent springs built into the receiver’s take-down pins, a beveled magazine well, and ingenious storage compartments found within the proprietary pistol grip and buttstock– both of which utilize o-rings for weatherproofness.

It’s amazing someone hasn’t thought of this before now: the ambidextrous safety selectors on the MR556 can be engaged at all times and don’t require a cocked hammer. The barrel extension, internal trigger parts, and bolt carrier group are all treated to HK’s own super-slick, self-lubricating coating. HK calls the trigger “an enhanced two stage,” and after dry firing, I can attest to that claim. It’s crisp and has a very smooth and definitive reset. The buffer is the best looking in the business. Who could miss the giant red center dot and brilliant HK logo? The buffer, along with its spring and buffer locking pin, are more robust than their standard mil-spec counterparts. The dust cover is polymer, which was odd– but I’m sure Heckler & Koch had a good reason for designing it that way.

The thick and heavy contoured 16-inch, 1:7 twist barrel is German-made, hammer-forged, and is NOT chrome-lined. HK believes the best accuracy is achieved via an unlined bore. In addition, the muzzle end has been swaged to achieve a slightly smaller diameter– which HK says improves velocity and accuracy.

The bolt is spring loaded into the carrier group and stays in the extended position– making assembly easier than a conventional BCG. The firing pin retaining pin is captive, so you won’t have to worry about losing it. The piston system itself is easily one of the most elegant and serviceable in its class– and that’s saying a lot. And the MR556-A1 ships with one of Heckler & Koch’s legendary steel maritime magazines, a handy tool, and HK’s signature front and rear diopter sights.

Perhaps most surprising of all is the price point. An HK aficionado is no stranger to exorbitant figures. At under $2400 for members of our exclusive VIP program, the HK MR556-A1 is in line with other premium gas piston ARs on the market and dare I say it, an excellent value. That’s all for today, my friends.

Have a good one and God bless!
