1. In an efficient, high-velocity compressed-gas-powered air gun, the improvement comprising
a) an action bolt assembly positioned between an upper body and a lower body of said air gun, said action bolt assembly including an action bolt which reciprocates within the upper body to fire a pellet from a rifle bore, said action bolt including
i) a probe carrier assembly comprising a carrier body, a probe piston which can reciprocate in said carrier body, and a probe extending from said probe piston and lying partially within said probe piston, said probe carrier assembly operative in a pellet-loading sequence;
ii) a striker for activating a firing sequence when released by a drop sear in response to a trigger being pulled;
b) a bolt guide encapsulating said action bolt, said bolt guide being manufactured of low friction polymer material facilitating reciprocation of said action bolt within and relative to said bolt guide.
