yip-Curious as to where your friend got his nosecap at or did he craft it himself? Would like to add one to a Kibler SMR build I have. They may not be correct, but I think a MZ without one looks as if something is missing and they do IMO protect the end of the stock. Not concerned about not being correct or they didn't have them 'back in the day'. I'm aware of the SMR rifle stock being thin and light at the end but I've seen pictures here and there with the K SMR having them.
