Dave (or anyone else) quick question... I bought one of these locally, internally blocked with extended floor plate tongue. I just got one from you (HiCal) and it is pinned with a rivet through the side near the bottom (where it would have no limiting effect that I could figure). Follower only goes down to 5 round limit, so I figure it also has the internal tongue on the floorplate.
Any idea why the rivet?
