Glad u got ur rail bro!!!!

I was checking pictures and I found the opposite "Hkey", in some MP5-MLI and MR762A1. Anyone know why? (opposite means small heads towards shooter, its weird)

[@Feldmutze]

As far as I'm aware, the MP5 MLI furniture is regular HKey. I'm not sure why they flipped it but HKey can be installed either way so I assume maybe it has to do with clearance on the MP5. As for the MR762 MRS "HKey", as mentioned in the video, that one is HK USA's own design and is completely incompatible with European HKey.

[@jhonsteke1596]

@@Feldmutze thanks, it seems HK USA's "HKey" also not available now. maybe it was just a little mistake during past time LOL.

[@jhonsteke1596]

@@Feldmutze some answers in Internet is that only the regular Hkey design can make attachment still during automatic fire. And HK use wrong design in few years in the past. Anyway at least now all Hkey is just like the video

Excellent info , now I'm curious about weapon light laws over there 🤷

[@borkwoof696]

In Germany? They‘re legal to own but not legal to mount on a gun for hunting or competing (which is most gun owners here)

Very interesting

[@merkava23]

watched all your videos - you've done a great job! Can you summarize all changes you've made to mr556 with some sort of rating from "must have" to "not worth it"? Thank you

[@Feldmutze]

Thanks! A comprehensive list would be too lengthy for a comment but I can do an in-depth video on it some time in the future. For a few of the key parts, I'd say: - NA5 gas block. Helps a ton when shooting suppressed - Non-locking takedown pin so you don't need a tool to field strip - Nefarious Arms chrome-lined barrel (very dependent on use case, but I like it as it requires less maintenance) Only part I've used so far that I'd say isn't worth it is the Waffen Burk gas block, especially now that the NA5 gas block exists as the NA5 is way better designed.

[@spinny2593]

@@Feldmutze Wait. I'm confused. NA5 has a 556 gas block or am I missing the "mr556" part of the question?

[@Feldmutze]

I didn't know there was another NA5, but in this case the NA5 I'm referring to is Nefarious Arms' MR556/416 adjustable gas block, which is a clone of HK's 416A5 gas block.

[@spinny2593]

@@Feldmutze No... that's my point. MR556 makes me think it would work on a 556 ar. That's what I don't understand. Does it?

[@Feldmutze]

Ah gotcha. No, it's just for the MR556, it won't work on an AR.
