Hammerless is a brilliant way to go for a semi auto since there is not near as much air usage because there is no need to operate a bolt probe to load a pellet and cock a hammer. Indexing a magazine is most of the air usage which is tiny by comparison. The slickest "new" feature is the ability to change magazines which other Huben type actions do not have. In this design (like the Huben) it appears the magazine is the bore since the pellet is fired directly from the magazine rather than requiring a bolt probe to load it into the barrel. IMHO
