So my MP5 22 SD has the collapsible stock on it which is cool, but has terrible cheek weld due to nothing but the two rods sliding back for you to rest your cheek on. So in my head I dreamed up something I might be able to fashion out of a hard block of foam, then either coat it with epoxy of use it to has a pattern and use a harder material. Mind you my sever lack of engineering skills dictates simple methods and easy materials to work so if it looks a little bit like a 3rd grader do it, that might be a compliment. lol I want something I can slip in between the rod of the stock and snap it in place and have a nice comfortable rounded top to allow a good cheek weld. I managed to go into Hobby Lobby (against my better judgement and wife spending $50) I managed to find a $2.99 block of hard foam to use. After about an hour and half I managed to come up with this basic shape to get the results I was looking for. I think I will try and coat this prototype with some clear epoxy and see how it does. If there need to be changes or I feel like scrapping it, no big deal. I would love to get something like this made using a 3D printer, but if it will cost alot I'll be happy using what I got. I don't know of anybody or local company that has such a thing so really I'm just stuck with this for now. Comments, suggestions.....
