A guy brought me a 38" octagon to round barrel and Rice's new Nock lock. He said to make him something out of them that would be an appropriate use of the parts. Trouble is, I don't have a clue as to what would be appropriate. I don't want to just slap a bunch of parts together and call it a rifle. In the books I have, I haven't been able to find anything showing the Nock lock that I could go by. Even searching the internet hasn't helped. So, I'm scratching my head. I'm hoping someone can point me in the right direction.
