Hello. I am currently working on an article about the rifles that militias own in Europe. During my research, I encountered with a Valmet rifle in Northern Ireland. I assume that its a milled M76 and thats why it has a long barrel (I'm not sure though). But Ive never seen this stock before. Some early valmet rifles have similar stocks but they are not the same. It would be great if you cam help me out. Thanks in advance.
