I bought a stock for a MP5/SP5 off a guy who has been collecting HK stuff for a long time.

I can’t tell if it’s actually H&K or a MKE copy (A3 type). There doesn’t appear to be any kind of identify identifying mark on it anywhere that I can see.

If I understand correctly, the German ones aren’t made any more and are actually pretty valuable.

Is there any easy way to tell whether it’s one or the other?

I’ll post pics later if I can get around to it.

The older German stocks usually have a date code inside a little rectangle on the top right side of the plastic butt piece (viewed from the rear). The newer versions still have the rectangle but no date code in it. I have a Turkish HK33 A3 stock and it does not have that rectangle, but I'm not sure if the MP5 stocks are the same or not.

other than what has been said above check the weld quality on the underside where it mates to the receiver, all my German stocks have a smooth clean fill, the clones have always been rough

Pics as requested…



Number on buttstock (or is it “IS”?)

Same number where it meets the receiver



Weld on bottom

Is the left side rail cut for a bolt hold open?

It looks like it is, I wonder if it is a universal stock or a tight close 10mm stock?

OP does the stock close all the way or when closed does it stick out a little?

There are two locks, one all the way closed and one just a little bit open.  I haven’t put it on a receiver, because that would be illegal without the right paperwork, but (theoretically, of course), it looks like the “all the way closed” setting would be pretty tight, with the little pin pressing into the buffer.

My guess is it is a universal stock (designed to fit either an MP5 in 9mm or 10mm or a buffered carrier HK33/93). When you get it on the gun it probably won't close all the way, because the rails will be too long (designed for the longer HK33, which is what the second further back notch is for). On an MP5 it will close sticking out a little bit.

Without putting the stock on your gun you should be able to put it alongside the receiver and see how long the stock rails are.

I believe that you are correct.

MKE stocks do not use that style of plastic lever/release, they use the older steel triangle lever.

My conclusion is that JsARCLIGHT is correct.

It’s an interesting stock- interesting enough that I need to get my form 1 in order…

1995 Oberndorf universal Hk53/MP5 stock.

Good pick up, OP.

Very interesting.

Not bad, considering it was literally sitting on top of a heap of other parts, prompting me to ask “hey, how much you want for this?”

Thanks for the info, folks…
