Hey guys,
Many moons have passed since I've posted anything on AR15. Maybe a year or two by now.

Got a quick question I know my fellow HK owners can help me with.

Is the HK MP5 Collapsible stock compatible with the HK91/G3?

I know it is compatible with the 94, and 93.

Thanks in advance

Well, you would need a backplate assembly that's compatible with an HK91. HK91 collapsible stocks use two stock pins and have an integral recoil rod/spring assembly, as opposed to an independent recoil rod/spring and single stock pin with an HK94.

91 receiver cross section is larger.

Just to add, putting a collapsible stock on a 91/G3 is a bad idea, due to the pounding that your going to take.

Nope.... MP5 collaspsible won't work on an HK-91/G3 or clone. You can get a stock like that though for around $200 if you look. Wouldn't be worth the time to convert an MP5 stock. Just sell it & get one designed for the G3.
