Hi Edgard, no this will not fit the MP5. HK makes a stock for the MP5 >>> https://hkparts.net/all-parts/hk-mp5-22lr-ump-style-folding-stock/
Stay safe & have a great day!

sorry this stock will not fit

Edgard, unfortunately the mp5 22lr and gsg16 stocks aren't interchangeable. So this wouldn't fit. Not alot of options available for the 22lr version. Here's a link to one I found on the hk website but little pricey. Sorry but hope this helps, link here....................... https://hkparts.net/product/mp5-22lr-ump-style-folding-stock.htm/
