John,
TR do sell the Bolt Action, they are the only distributor (I believe ) outside the US allowed to stock it as PSI are keeping the pen close to their chest until the initial demand has subsided then they will probably release it to the rest of the world. The Bullet kit from Timberbits, in my opinion is much superior to the bag of bits that you get from PSI, it is a much better engineered kit and the clip is stronger, the rifle points along the pen and not back at the writer meaning with the timberbits pen the rifle stock is the interface with the top of tyhe pen, not the end of the barrel which is obviously weaker and doesn't feel right, the gun pointing in the opposite direction of the pen is just odd! If you order more than $200 then the kit will arrive, if you order on a Thursday, on the Monday morning cost free courtesy of TNT but you will get a love letter from George and the boys at the HMRC.
