An improved paintball marker bolt and bolt head uses a curved gas inlet ramp and geometrically designed outlet holes to provide pressurized gas flow with decreased turbulence and more uniform distribution over the paintball surface. The improvements in gas flow and pressure distribution are combined with other mechanical improvements related to drive transfer, friction reduction, and bolt assembly, resulting in a significantly improved marker bolt. Improvements are realized in increased gas flow efficiency, increased paintball velocity (by 30 feet per second or more), increased range, improved shot consistency (less than a 2½% variation in shot-to-shot paintball velocity), decreased jamming, and decreased premature paintball breakage.
