Can anyone mill an extra notch in the MP5 collapsible stock to make it a 3 position instead of 2. Its too long all the way open.

Thank you

Of course someone can. Consult local machine shops, or ship it off to ADCO.

Contact TPM Outfitters, Investment Grade Firearms or TSC Machine.

Dremel can set you up with a fix.

I would recommend getting one of the A3 "F" stocks which have multiple lock positions. An original H&K A3 "non-F" stock is a pretty valuable piece to be hacking on these days.

I had this done to an earlier G3 A3 stock. My local gunsmith said that thing was made out of Valerian steel....I ended up sending it to HKparts.net and they did a great job on it. It is a lot more complicated than hacking on it with a dremel...

Thanks y'all.

Yea I tried with a dremel for about 5 minutes and realized that was not going to work haha.
I contacted ADCO, TSC, TPM, we'll see you emails me back. I'm happy to pay to have it done right.

I have a F 4 position but I don't like it. I don't like having to hold the lever over to get all the way to the third position. Just want to pull straight through to the one I want. Also I don't like the curved pad on them. And yea these damn HK parts are such a rip off, but not much choice I guess. I have $2,500 just in stocks haha. Crazy! It makes the suppressors seem like a great deal haha.
