I'm looking in to getting a custom barrel for my t1x. I've seen in other forums that Shilen, Lilja, and PAC-NOR are all options. Lilja is undetermined right now, the forum posting was a few years old and I don't see 17cal on their site. I'm leaning towards PAC-NOR right now. Anyone put a custom barrel on their rimfire (stupid question)? Any other manufacturers I'm missing?
