I knew you used rifles with recovered receivers from some of your other threads. When I picked up the receiver I asked if it was covered and he admitted it was but were easy to repair. He let me pick the best looking one out of 5 he showed me.
By the way I enjoy your how to threads. I like picking other people's brains on how they do things. I listen try different techniques and then use the one I like best. My Dad always told me you can learn more with your mouth shut than with it open.
