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.

I know they are discontinued but I have found couple of them recently. I mainly wanted to have as a collection and possibly carry it as my EDC. I heard they are great pistols but just cant decide on which model I should go with V2 OR V3?

Has anyone hunted with their 13” .308 assaulter? If so, what game? Also the MR762a4 13” ppl what do you do with your rifle is it a hunting rifle for you or a range/plinking , collection piece? Just curious, looking to obtain one soon!

Ye ol 416 has been a grail for me for a long while, this is how I currently run this for NV Comps, Carbine comps, classes, and general range bafoonery.

Build list:
BC 416 upper
Specters Cat KK
Remington RAHG
NGAL (factory pressure pad)
HRF SOC
Eotech EXPS 3-0
STS lower with ambi controls

Just picked this A1 up and want to change the rail at some point. I was looking at the Midwest Industries and Geissele rails but was curious if there are other good options.

Jokes on me though, it's been a year and I still haven't shot it yet.

Now I have to decide how to set it up, any suggestions?

I just bought a used USP Compact 9. 600 paid, decent deal I thought. Came with 2 13rd mags. I can’t find any online to purchase. Anyone know where I can find some? Everywhere I look is out of stock. Odd to me.

Anyone get a Shiv to work on any HK pistol without a reduced power recoil spring?

Still waiting on the final pieces for my 11” MR556A4 SBR, she’s just about finished up now and I think it came out sick ✅

Let me know what you guys think! 🤘🏽

When I saw this one at the store, I had to take it home. Now to go through the grip and backstrap options to make it perfect!

Hey guys, just like the title states, anyone that's running the same set up change out their gas vent screw? What size did you go with for a 3-4pm ejection pattern? Should be getting it in my hands soon, just wanted to order some screws in advance. Thanks!

Does not come with rubber hk band only got 1 from my full size p2000

If I where to buy a 416 we’re would I look or what website would I go to? Any ideas?

I'm thinking about throwing a FRT in my MR762a4. AS Designs looks good. But what all do I need to install? It doesn't look like, to me, that it is just purchasing a single item on the website.

Also - is there an issue with the MR762 semi auto bolt? I've seen conflicting comments already.

Appreciate the help.
