I just received mine from this recent batch, ordered 5/21 delivered 5/26
It is WAY out of spec.  I will be contacting @atlanticfirearms for a replacement and just hope it’s better

Any details on what is out of spec?

Mine should be here in a day or two, will see how it fits on my AP5.

Basically the entire end cap.  I spent about 1hr this morning bending & reshaping and was finally able to get it on.  At least the pin hole did line up.  My only concern now is removing it for cleaning, maintenance etc.

Mine arrived today, went right onto my AP5 Navy with zero issues. In fact, it fit on and slides better than my H&K A3F stock.



Only complaint is the release is clocked at about 6:30-45 instead of dead nuts 6:00.

The release on mine is clocked the same, about 7

My only other experience with MP5 retractable stocks is with second gen HK A3s and the A3Fs, both have the plastic release that sits right at 6:00. But, perusing photos online last night of the older first gen HK A3 stocks, I found many that appear to be offset like my MKE A3.

It’s difficult to slide in and out. I’m used to these types of stocks, im sure it will wear in with enough time
