Omega all fixed. I found the screws at the local hardware.
I got 2 socket head 10-32 screws. I decided to get stainless.

3/4" long for the front and 1/2" for the rear lug.

I had to cut off 2 threads on the front screw so the ramrod had clearance.
The addition of the neoprene washers to the lug slots totally floated the barrel.

I'll be checking how it'll group in the morning. If all is OK, I'll be off to my stand in the afternoon.
