H&K rifles

I would think all Nato countries use stanag?

I don't know where this internet FUD comes from. There is another rifle called the MR223 that sells in Europe and Canada. It is NOT AR15 compatible.

The MR556A1 is AR compatible, and the upper works just fine on any AR lower.

Here's a review from MAC, fast forward to about 17 minutes in if you want to see the MR upper on an AR lower:

Does the 416 upper work with the AR lower? It sounds like it does. Haven't seen the video.

Yes, the 416, and MR556A1 uppers both will mount and work on a standard, in spec, AR lower. Initially, before the the MR556A1 actually came out, word was they were going to have non standard pin spacing and were not going to be compatible with standard AR lowers. That proved to be untrue. That's where the continued mis-information comes from. It is a marvelously designed and finished rifle. There is a steep price of admission, and whether or not the features and quality justify the price is purely up to the individual buying or passing on it. The HK mags are typical HK quality. Again, only the end user can determine if they are "worth" it. Pmags are not made to USGI/stang spec. That the MR556 doesn't jive with them is of no concern to HK. Neither does the scar 16 or the fs2000 and I'm sure several others. Doesn't make pmags pos, just means you need USGI in the HK and FN's.

Congrats to your buddy on his new rifle op. I'm sure it will serve him well.

The HK "High Reliability" mags were designed as VERY EXPENSIVE USGI mags because PMAG's won't fit in a HK416 lower and the HK416's couldn't reliably use standard USGI mags.

Honestly, they were a solution to an HK problem.

For the price of one HK "High Reliability" mag, you can get three PMAG's. And I'll take the PMAG's over the HK mags any day of the week.

Yes, the HK416 is unreliable, in fact USMC awarded HK a contract to produce the M27 IAR after beating all well known competition. Although unreliable, the HK416 proves to be the "best of the best".

The HK416 and the M27 IAR are not the same firearm.

I've read MANY stories of the 416 being unreliable with anything other than the HK High Reliability mag.

If your gun is not consistently reliable without a $60 magazine, then I'm not interested.

Then again.. It's a piston gun. I'm not interested to begin with

CHS, I usually have a lot of respect for what you have to say, but you're starting to sound like a crusty old fogie that only likes colts and 1911's, lubes his guns with grease, and thinks anything that wasn't made 100 years ago is crap. I know you're too good a guy and too smart a person to fall into that silly stereotype.

HK416's and M27's are almost identical insofar as working mechanisms are concerned. The 416 has evolved somewhat over the years, and the most recent 416 is actually very similar to the MR556 insofar as the BCG modifications that have taken place.

The M27 IAR is exactly the same as an HK416D with several exceptions:

1.) The M27IAR has an 11" handguard, the 416 and 556 has a 9" handguard (stock, the 11" is available from HK and fits any of their varients) The longer handguard allows the attachment of night vision equipment forward of the standard issue ACOG (same ACOG that comes on the SAW)

2.) Because the handguard covers the piston block, the M27 has a forward bayonet lug around the barrel, facilitating the attachment of a bayonet.

3.) The M27 IAR comes with KAC full height m16 style BUIS instead of HK diopters that come on the 416 and 556.

Everything else is exactly the same. As I mentioned, the USMC uses USGI mags in the M27. The lower is exactly the same as the 416 and MR556.



IF, for some reason, using Pmags is an issue for someone, replace the lower. Lowers are what, $99 these days? That's small potatoes, most people spend more then that for a "tactical" light they never use.

The Magpul P-Mag are not STANAG.
Hence the reason why Magpul makes the E-Mag, which is suppose to be STANAG.

Agreed, I respect that a reliable Pmag is more important to you than the firearm. I guess the thought process of USMC in spending $60 for a magazine is Marine lives are on the line.

HKs' don't break

....but your wallet will.

So true. LOL.

Good to hear. Does it really make a difference in my Spikes lower? I'm assuming it's milspec, that said, I wonder if I should go with Emags just because there stanag?

PMAG's were designed strictly for the standard forged AR15/M16/M4 magwell, which is what your Spikes is. For that, they work excellently.

STANAG magazines (like USGI mags, or EMAGS) are designed to store and feed 5.56 cartridges for NATO weapons INCLUDING the AR15/M16/M4 but also include things like the British L85/SA80 which DOES NOT have an AR15/M16/M4 magwell.

A magazine not being STANAG compliant is only a problem if you're not running the AR platform.

Now, if you ever plan on getting a MR556/416 or an SA80, maybe you should invest in EMAGS

Aye ok right on. Damn....my dream rifle was that SA80, to bad no one imports them!

thanks for the mag knowledge.

Emags are also more expensive. So, unless you really need to, I would just stick with the Pmags.

^ good to know!
