Had a blued WH M1A1 that we had to re-machine the mag well in. I then had the local gunsmith re park it a dark blue/black . Came out a very light gray . Would not correct it. At our last spring shoot , the front sight pin broke and the sight came loose , and the rear sight pulled it's rivets almost out. As per recomendations I contacted Tommygunner to fix . He reinstalled the front sight , rear sight , replaced the foreend hanger with a one -piece , and blasted off the old park and "blued" it with the black oxide. Just had her out this last weekend after getting her back a month or so ago. Function perfectly and all six shooters gave the refinish two thumbs up. Works for me. http://tommygunner.com/pages/services/index.htm Chris
