Hi John,
I wrote this as you were replying, but I will post anyway. Hopefully Mike will reply also.
Good job on your first rifle. Inletting looks well done. To echo Mike, the lock panels aren't bad, but could be better. I would suggest not following the lock outline so closely around the nose and tail of the lock. Stretch those out a bit, 1/2" or even a little more, and blending them into the narrow upper and lower edges will look more graceful.
What are you think of for your next build?
