Just picked up my SP5 and SBR'ed it. Now looking for a German HK MP5 Rear Sight Drum or Sight Assembly with Diopter.

Anyone have any leads on one? I prefer switching the sight assembly for ease.

@under9

There is one on GB right now for 89.00. Look in HKParts category.

Off topic but what parts did you change for 922r compliance?

As of right now, none. Not totally sure what the best route would be.

Is that needed when the german rear sight is swapped to another German one?  What about putting a US made thread protector on it?

Or do you mean if adding another German part such as a stock you have to add another US compliant part?  Sorry not too familiar with 922r stuff lol

6 parts need to be of USA origin to make an imported pistol 922r compliant in order to become an SBR. So you need to pick your poison on which you choose to do. The fore arm, charge handle, magazine (counts as 3 yet anything other than HK dont function fer shit).... A PTR rear diaopter sight all in itself might count as the 6 if all manufactured in USA and you can get one. Others are saying that even a suppressor if made in USA counts as flash hider so that is 1 part? An after market butt stock..Me, since I'm buying German for German engineering, I would choose those that are more cosmetic vs mechanically functional. I'm leaving my lower internals alone but those could be change out as well.

I got mine from HK parts. They sent me a fake one, claimed they made a mistake and send me the real HK after.

I would/did choose all German parts for that reason. 922(r) isn't something most people ever have an issue with. They'd have to prove you assembled it anyway. If anyone besides the possessor assembled it, no problem.

Possession of a non-922(r)-compliant firearm is not illegal; only the assembly is.

The statute of limitations is 5 years.

{Invokes Fifth Amendment right about now.}

If they're asking about 922(r) though, you likely have other, far more serious problems.

Just FYI, I don't think the flash hider is included in the count of 6.

Most don't come with a flash hider so adding one (including a silencer) doesn't count towards swapping 6 parts out.

Ive always wondered how one could tell if something is 922r compliant

Sure usually some of the 922r options are marked USA. But whos to say your no marking sight is or isn't American?

Furthermore say you modify a foreign part. Is this now a USA part?

Good to know. Thank you for the correction.

does form 1'ing not count as adding a US made part since you are manufacturing a short barreled rifle here in the USA?

There are only certain parts that qualify.  A rear sight is certainly not any that qualify toward 922r.

Yes. Is see that from that list linked. What a shame. Almost like they don’t want your German, reliable gun to be so with the list the compiled. I can get to six but would have to change out the sear. But that USA trigger box  is expensive from HK parts. Wonder if any of the customs shops make their own boxes and do they fit HK. Someone like Dakota Tactical.
