HK has some impressive barrel technology. Of course, the price tag is also impressive:
The price tag is full blown retarded… like HK fanboys.
Ambi lower - hate that nonsense
45 degree selector - more silly nonsense
MLOK rail - HELL NO. At least the Czechs got real pic rails.
And the big no no - A piston AR. The cherry atop the unnecessary nonsense features cupcake.
The B&T can was the only interesting thing in the video. But I’m not into running suppressed ARs much these days… even with the “flow” can designs, I’m not convinced it’s safe.

Exactly. I fail to see what this rifle actually does in real world use that a $1k Colt Trooper doesn’t do equally well.
Saw the neutered civi version is still 9lbs. Eat a dick.
Unlined barrel, 9.5 lbs unloaded, all for $3,900.00, I’ll pass. You could fully outfit a 6920 and save $500 for that kind of money.
Fully outfit as in:
Colt 6920 $1,100
KAC RAS handguard $450
KAC rear iron sight $250
Surefire scout $350
ACOG $1400
That adds up to $3,550.00
For a little extra flavor, you could toss in a Geissele SSA-E on a Black Friday deal for about $175.00.

I completely disagree with some of you. It’s another cool weapon. Nobody claimed it was the best. I own 7 colts, A few Sigs (MCX, 516, 716 G2, LMT and others. The price is high for sure. Putting down HK fans is stupid. Why do some of you hate on other weapons so much. Damn.

I don’t see enough difference to justify it over the two MR556’s I already own. I have no need for ambi controls and I already have MLOK handguards on both.

Could buy the Brownell’s BRN-4 which is a great copy and have lots of money left over for optics etc. Theirs has the chrome lined barrel and isn’t ambi. Nefarious Arms has the dimpled cool guy barrels and A5 gas block if you want to cut weight and fancy it up.

HK still won’t chrome line a barrel for us peons. WTF? I know, I know, import/export regulations…hell, chrome line them here since we obviously have the ability to do so.
That price tag is a bit over-the-top.

Barrels are high chromium content machine gun steel that are supposed to be more corrosion resistant than standard barrel steel like 4150… HK USA claims they’ll withstand huge round counts without losing accuracy, AND that they will replace the barrel for free if you shoot it out.

Most people would never shoot out there barrel regardless. And while I get that its a great guarantee its also a marketing tool. Unless you simply want a HK in the safe, which is cool don’t get me wrong I dig their products, your money could be spent better if your wanting a solid piston based M4 option.
Does the pistol version have a pistol buffer tube or is it the same tube that’s found on the 16.5” version?
Seriously considering one of these
The funny thing is HK fanboyism is easily outdone by anti-HK fanboyism.
Yes, they are pricey, but let’s get one thing straight, they make good sh*t no matter what you think of the price. Same with KAC, LMT, Barret, etc. You decide if it’s worth it or not.
The “shitty un-chromed lined barrel” is =<1 moa and is considered to be “out of spec” and recommended to be replaced by HK at over 10,000 rounds when it shoots 2moa. Wow…what complete sh*t 
Here is a direct HK response about that specific question:
Why not offer a proper chrome lined version as well?
For a semi-automatic firearm, using HK’s steels, US chrome lining provides no significant benefit and can actually hurt performance (more on this later).
However, one might argue we are offering a chrome infused barrel.
The common barometer for a barrel in the US is “Mil-Spec” which is governed by MIL-B-11595E, commonly referred to as 4150 CMV. This chemistry is required to have .8 % to 1.15% chrome. Due to this low chrome-content, a chrome lining is effectively required to provide the barrel corrosion and abrasion resistance.
As comparison, the alloys HK uses are typically 3% or above. This high chrome content (and other alloyed materials) makes the HK steel naturally more resistant to corrosion, abrasion, and wear.
We are offering the barrel with the best combination of accuracy and durability we can. Each MR A4 leaves HK having been tested for accuracy. All rifles must meet a 30mm maximum dispersion at 100 meters (effectively 1 MOA or less). We consider a barrel shot-out when the base dispersion doubles, which should far exceed 10,000 rounds. We’ve taken guns well past this.
We are so confident in this, we guarantee it. To our knowledge, no other semi-auto rifle manufacturer provides a lifetime guarantee against barrel wear.

An inch is 25, not 30mm.
SOLGW offers a lifetime guarantee on unlined barrels. I’m guessing HK didn’t look very hard before claiming that no one else they know of does.
Whoa, a whole 5mm…(4.6 to be exact). That makes a huge difference! OK…One other manufacturer offers that guarantee but does not have that type of accuracy. That’s your argument? Seriously?
Argument? Nah, I think they’re probably high quality barrels and good shooting guns. Just clarifying a 20% conversion error.

Ah, the magic HK “Pixie Dust” ingredients for barrel steel! SMH
That comment from HK, specifically “US chrome lining provides no significant benefit”, leads one to wonder if they are suggesting that THEY can chrome line one better than us? Also, if chrome lining is so unnecessary, why are the real-deal 416’s chrome lined? I’m not talking the ones made for mil/LE here, but for the military contracts they have in Europe too. I don’t see the real 416’s being sold to militaries reliant upon the “Pixie Dust” barrel steel alone.
While I prefer chrome, HK could at least Melonite/QPQ/nitride the barrels, which is better than nothing.
The offer of barrel replacement is dandy up until such time as HK changes their mind or it is legally impossible to do so (i.e. some future AW ban or similar).
As someone on another site pointed out, if you’re going to pay a premium price for a firearm—and damn near $4K is “premium” in my book—then it should include such minor things like chrome lining.

I get it…some people want the chrome lining, but if you look into why they didn’t provide it, their conclusion was that it only benefited in the case of extended full auto fire. Other than that, it lessened the accuracy. So if you are HK and are providing a semi auto version of a weapon, what benefit does chrome lining provide to this platform when they have tested it past 10,000 rounds? Nothing. It just takes away accuracy. They are being logical Germans.
Well, “They are being logical Germans” with a hint of Germanic snootyness when it is suggested that THEY are the primo purveyors of chrome lining! Fvcking Euros…

When it comes to military style firearms, I want my semiauto to be as close to the fullauto version as possible. If the fullauto has chrome lining, I want it, logic be damned.
Back when I was a teenager, my mother was looking at buying a BMW. She noticed that it didn’t have a cup holder and asked the sales representative about it. He said that they didn’t include them in the design because the engineers don’t think that people should be drinking while they’re driving. Perhaps that’s true, but it cost them a sale. The Japanese car that she bought had two cup holders. Apparently, the Japanese don’t have an issue with giving people what they want.
