Does anyone know if the GsG5 uses the same end cap as the HK .22 MP5. Has anyone tried to use one end cap on the other?

Im not sure but I have the HK branded 22 and I bought an end cap from CSM.

No, there not interchangeable. Some of the airsoft models will work, might need slight modification.
Unfortunately I can't remember atm what brand airsoft is compatible with the gsg.

Ok. I just ordered one off of Evike. Gonna try it out. I’m looking for a different local source other than Classic Army. They’re getting hard to get and from overseas.

Old post but what did you order from evike and did it work? I’m in the same boat.

Normal MP5 airsoft stocks will work on the GSG. I have an A2 on mine… the HK .22 versions won’t fit- they made the receivers a different size so people couldn’t go this, for some odd reason.
