What was supposed to be a much anticipated clone of a Beeman R-9 by the Chinese.
RWS started importing them but Fun Supply who had been selling the Xisco B-20 which RWS relabels stopped carrying them because of so many quality control problems from the factory even after he's complained. He gives a lifetime warrranty on the chines guns he sellls, so he's picky on what he carries.
He now carries the Xisco B-21 and B-22 which are chinese clones of the RWS 52 and the XS B-19 which is a chinese clone of the Gamo rifles.
