I have a nice Hungarian T3 kit that I am wanting to build! I have a couple of questions! First off what makes a threaded receiver better then a press and pin? Is it really that big of a deal to turn the threads off and press and pin? Also is it possible to get the receiver Serial number to match the kit? And finally I would like to keep the original finish on the rifle. Can just the receiver be blued to match? Any advice would be appreciated! I don't have any T3's in my collection right now and just really want this one to be as nice as possible!
