So that I can be a good subject while still in The Bay State, does anyone have any tips/suggestions for pinning a collapsable stock for an AR-15 build?
See that sliding locking pin? Order a few, using a dremmel, cut it so it sits flush or below the edge of the stock surface, install, Done. Correct me if I'm wrong but that should be legal pin job.
If it needs to come out. Use a dabba S-Glue, pull it back, slide off stock over tube.
