Thanks for the post and the detailed explanations of your work! I am new to this site (as a member, anyways) and am glad that I looked in the forum section! I originally only came here to drool over the gear that these fine people make, but soon realized that there was a forum! I installed the flush cups and mounted a rail on my rifle as well as added my own paint job. Here is a picture of my finished product, thanks again for the guidance!
