Pics
Go back to the AR15 thread, titled Hy-tech fitting... I updated it last week, added some pics. I like you am challenged by lack of pics to go along with the text. All work was done with a 8" flat lathe file from Sears and a course 5/16x8" rat tail file, though small finer cut chainsaw file might tak a bit longer, and look nicer, but you just want to open the radius to allow radius on mag' rear corner to slide in.
