C you can soft solder on the ramp. I use the ribbon solder Brownells sells.
If you brought that to me to fix, I would but barreled action in my Foster jig and drill a spotting hole that the screw would fit into. Not tapped , just major diameter.
Clean blue off of barrel and bottom of shorty ramp
A twist of tie wire and a kittle flux and a piece of ribbon solder.
Propane torch and presto.
That how this Trinadad State Junior College graduate (84) would do it.
