I found this at a dealer and was attracted to the ambi stock with some nice figure in the wood. The Hawke 4-16 SFP AO and IR was already on the gun. I added the DonnyFL KOI moderator I found used. It really likes JSB 10.34 gr pellet. At our indoor 50-foot range it is fun turning aspirin tablets into dust. As I understand it, the Streamline was replaced by the Dreamline. I have not had the opportunity to handle a Dreamline, but I like this one.
