Some pics of my Remington P14.

I don't know when this repair was done possibly during it's Weedon refurb. It's very solid.
The crack is between the red lines the dark circles of 2 dowels can be seen on top next to the sight base.

I don't believe any other type of repair will hold as long or be as strong as this one.
There is no trace of this repair on the inside of the stock.
From a few inches away none of it can be seen you couldn't say that about a repair done with screws.

Please excuse the spastic lines I did them on my phone. Bill
