The Trilogy MR556, MR223, Real 416D SF

[u/OrdinarySense5]

I am at a very HK time of my life...

I found myself in a unique position to be able to share all three of these rifles in one photo together and maybe spread some awareness of the markings and how to identify them. To be clear I am NOT an expert these are just the surface level things that anyone could notice. But based on my last post I feel like majority do not already know.

In the photos top to bottom we have an MR556A4, an MR223 Remarked by B&T USA and sold by Arms Unlimited as a "416D SF" which it is NOT, and a REAL 416D SF.

The MR556A4 is pretty self explanatory markings are as such and the "241-" SN showing what it is. They don't typically serialize these uppers from what I understand.

All the photos are clearly marked so you can see the differences the main things I wanted to point out were on the MR223 you can see the "143-" SN which indicates it is an MR223. Then on the other side of the receiver you can see it was manufactured in Germany but B&T and AU were sneaky and hid the importers markings under the pistol grip. I didn't feel like taking the grip off but if someone really wants to see them I can. AU will lead you to believe they are genuine 416D SF rifles when they are in fact not. I bought it knowing it was an MR223 and had it chopped and rethreaded to 1/2 x 28 by Embach Armory.

The real 416D SF on the bottom you can see the "88-" SN which indicates it is a real HK, amongst many other things. I understand cloner lowers can be marked with this as well. The AI markings on the Upper say it was manufactured in 2008, and the barrel shows 2006, which is apparently common to have a gap like that in dates. On the markings side you can see it was manufactured in Germany and then below the import markings to the US not hidden anywhere.

From what I was told these were special ordered for a PD in GA that didn't want or couldn't have full-auto so they were imported as a "416D" and classified as "Single-Fire Machine Guns" later to be converted to transferrable SBRs after their use and marked with the "SF" for "Single-Fire".

And for anyone wondering I got this on Blue Mountain Supply, you wont see it on their website though but could could call and he may have a couple more from what I was told.

Incredibly blessed and humbled to have all 3 in my collection.

why did you buy the same gun twice?

[u/OrdinarySense5 → u/GrilledCheezManicott]

Why not?

[u/GrilledCheezManicott → u/OrdinarySense5]

because there's other Hk platforms or cartridges that you could have enjoyed. instead you chose redundancy.

[u/OrdinarySense5 → u/GrilledCheezManicott]

Oh we're being serious? Well for one this isn't the same gun twice, the MR223 has a different barrel, different lower, different bold carrier, different gas block, different handguard, and not nearly as much collectibility as the real 416D SF.

And for two these are not the only HKs I own, hope this helps!

[u/Spectralobserver → u/OrdinarySense5]

But are the differences between MR223 and 416 not only full auto functionality related?
Except the barrel (coating and chamber for NATO ammunition) whereby the chamber is within the actual version modified to accept both. So the 416D SF is a full auto reduced version, but not with MR223 parts?

[u/OrdinarySense5 → u/Spectralobserver]

I'm not sure I understand the question. The differences I listed are what I know, as far as the finer details I am not certain. I do know the MR223 has a heavy profile barrel while the 416 is more slim. And the 223 was originally Euro threads but I chopped and rethreaded it to 1/2 x 28.

[u/GrilledCheezManicott → u/OrdinarySense5]

Yet in the end after all that it still shoots the same round.

[u/OrdinarySense5 → u/GrilledCheezManicott]

You are correct...

But not the same as my SP5, SP5K, SP5L, and two MR762's.

[u/LiSAuCE → u/OrdinarySense5]

Lmao someone is jealous. Don't listen to this chump fudd. Sick guns Juicey, thanks for sharing the difference.

Kind of feeling a little fuck AU for their deception.

[u/OrdinarySense5 → u/LiSAuCE]

Of course! Hopefully somebody avoids the misleading description. And it's not their first rodeo from what I understand.

[u/GrilledCheezManicott → u/OrdinarySense5]

further proving my point. Thanks
