I have this B&T stock...

HK MP5 UMP Side Folding Buttstock - BT20155-D S Arms

Seems like it would fit on the HDPS block and give it a shorter LOP. Has anyone tried it? Should I try it?

Haven't tried it personally, but wow that's a lot of money for a stock. You can find US-made stocks for $100.

Well, I already have it and it's just laying around... Thought it would be cool to try and give the UMP a different look.

Does it have the same holes as the UMP stock block for the stock pin? It says in the description what guns it fits. Just curious...

 

[Lohe]

I've read in a few different places that it will fit. No personal experience with it though!

The stock fits but the pin holes don't line up... no way around it unless you make a permanent modification.
