I just found and joined the forum. I only own a lowly semi auto but I have a form 4 in the works for the short barrel. I'm also looking for a M1 buttplate with the milled trapdoor. The only place I found that has them for sale is Tommygunner.com. No emails have been returned and no one answered the phone today. Anybody do business with this individual? Can anybody direct me to a source for this part? Thanks for any help, CB
