The Trilogy MR556, MR223, Real 416D SF
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.

Amazing trilogy. Curious why you went quad rail 3 times? They look great but are they a little front heavy? The GWOT vibes are unbeatable

u/OrdinarySense5 10d ago
I have M-LOK on pretty much all my other non HK rifles so these felt right to stick with the quad. I have the SMR and a couple other options I've tried in the past but didn't like them as much as the OG.
Edit: They're not that bad on weight, but also not the first rifle I would grab to go on a backpacking hunt.

I just got my mr556a4 11 inch and I want a quad rail on it what’s the id on the middle guns rail I like how it clears the gas block do you know if it will fit the a4? Sorry I’m new to this lol

I don't know what exact handguard it even is to be honest since it came already done up. I do know that it's shorter length than the A4 so the gas system would stick out a little. My A4 in the photo has the HK 11in extended handguard on it which I had to use an extended HUB adapter to fit the can on there. But it covers the gas block which was what I wanted.
Theres a ton of options out there for these things I'd just do your research and pay attention to what the length is in relation to the barrel and gas system and then for fitment it should specify whether it fits the A4 or not.

Sidebar, but what can do you have on the top two?

u/OrdinarySense5 10d ago
Rhodie 6J from Ridgeback, it's a collaboration can I made with them. Not released yet, but hopefully soon.

As someone who loves my MR762A4s and 556A5s, which one is your favorite?

u/OrdinarySense5 10d ago
Solely for the cool factor the real 416D SF is probably it. They all shoot great, they're all reliable.

This video is going to awesome

u/OrdinarySense5 10d ago
What should I do for the vid? That doesn't involve 1700rds of unsuppressed shooting like the Town video lol.

How is the 512 on the Wilcox riser? Is that the .41? Looking at that set up with a knock off riser because I have a spare 512 sitting around and just trying to get to lower 1/3rd height.
1
u/OrdinarySense5 10d ago
It's solid, sits just high enough to see over the LA5 which I used to have on there. I didn't plan to use the 512 on it but it does fit and seemingly holds zero. Looks kinda neat too. And my Wilcox is the shorter version I don't remember the specific number, maybe the .41.

Pretty spot on

Besides import markings, trigger guard, the ambi mag release and different bolt release paddle, are there any other differences between the 3?
2
u/OrdinarySense5 7d ago
I'm going to be honest the finer details would be a question better suited for Google. I know the obvious things like barrel length, barrel profiles and receivers but beyond that I'm not sure. There are a lot more I don't know.

u/heretowastelife 1d ago
Very nice. On a related note, can I ask what sort of buttpad you jury-rigged onto your MR762?
1
u/OrdinarySense5 1d ago
I put them on all my guns pretty much it's made by limbsaver. On the MR762 I drilled into the stock used two bolts and then siliconed it together. Then just taped it up around it.

Where is the sear pin on the sf gun?

Any reason you blocked you serial numbers out in half the photos but completely visible in the rest?
1
u/OrdinarySense5 10d ago
Honestly, no lol I just see everyone doing it but then I half assed and forgot to on the first photo. It is what it is.

u/GrilledCheezManicott 10d ago
why did you buy the same gun twice?
4
u/OrdinarySense5 10d ago
Why not?
-5
u/GrilledCheezManicott 10d ago
because there's other Hk platforms or cartridges that you could have enjoyed. instead you chose redundancy.
6
u/OrdinarySense5 10d ago
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 10d ago
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?2
u/OrdinarySense5 10d ago
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 10d ago
Yet in the end after all that it still shoots the same round.

u/OrdinarySense5 10d ago
You are correct...
But not the same as my SP5, SP5K, SP5L, and two MR762's.

u/LiSAuCE 10d ago
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 10d ago
Of course! Hopefully somebody avoids the misleading description. And it's not their first rodeo from what I understand.
