Umarex HK VP6 - HPA adapter

Hi guys
Just wanted to ask if anybody knows if there is a hpa adapter out their for a hk vp6, I’ve been told that they are very similar to glock mags and was wondering if it would fit onto the gbu “universal” hpa adapter.

Just asking if anyone has had experience with hpa adapting no common guns and since the gbu hpa adapter fits “glock style” and the hkvp6 is similar to glock? Sooo yeah…
