Thanks Jon, it's all in the FAQs, the only change I know H&R is really interested in is the lower hammer spur and lighter hammer extension ala M94 Winchester style, I sent pics of that to them. It's real easy to improve a factory extractor by using a factory ejector and a short spring between the extractor cam and the ejector to push the case out further, I haven't modified a factory extractor to work that way yet, but it could be done, the extractor is longer than an ejector, so it would have to be shortened and the forward end modified.
