Maybe this should have gone to the stock forum. Wasn't sure, so here we go.

I am working on bedding my 12. It has a machined lug from Northland. The index on the lug is a socket head machine screw.

The allen head opening on the screw peaks out a little under the receiver, creating what appears to be a perfect cavity for a small mechanical lock with the bedding compound. How should I prep this? Pack it full of clay? Tape?

I look forward to hearing your opinions and advice, thanks.
