The mag tube screws in so I dont worry there, and its only button mag. BUT, I wonder bout forewood shifting thus loosening forewood cap over time. So I wonder whats best there? Should I drill for threaded rod to hold wood to receiver, or what would be bast to keep things from jiggling loose. Before I hear it. Folks like wild west and Zhat will not divulge. They dont care if ya get killed. They care about adding to their already mammoth piles of $. So any help appreciated
