A high flow bolt for a paintball marker increases the efficiency of energy transfer from a propellant charge to the paintball projectile by increasing the flow rate of propellant through the bolt. Gradual transitions, increased sectional area flow passages and an equalizing chamber synergistically combine to improve the efficiency of the marker by up to 30% or more. A more efficient marker provides more shots per unit of propellant.

A gas release valve for a paintball marker employs a uniquely configured gas flow passage to improve gas flow through the valve and enhance the performance and efficiency of the marker. A short axial intake portion of the gas flow passage meets an angled exhaust portion at an angle of approximately 120. A transition surface at the intersection of the intake and exhaust portions is at least partially defined by a portion of a sphere. The valve body defines an internal spring chamber in which an elastic o-ring engages a radial groove on the valve stem to hold the valve bias spring in compressed relationship inside the spring chamber. The o-ring also seals the valve stem to the valve body and supports the valve during reciprocation. The disclosed valve configuration improves the efficiency and ease of assembly and disassembly of the gas release valve.

A gas distribution device for a paintball marker includes an exhaust hole for venting pressurized gas from the device and associated plumbing. The exhaust hole is axially located to be uncovered after the valve pin of the compressed gas cylinder is released. A controlled venting of pressurized portions of the gas distribution device and plumbing is effected without cycling the paintball marker or removing the gas cylinder.

Disclosed herein is a magazine release. The magazine release includes a spring retainer slot and a spring channel. The spring retainer slot is spaced between a first end and a second end of the magazine release. The spring channel is at a bottom side of the magazine release. The spring channel is adjacent the spring retainer slot. The spring channel is spaced from a top side of the magazine release. The spring channel extends between a front side and a back side of the magazine release. The spring retainer slot includes a first depth from the bottom side. The spring channel includes a second depth from the bottom side. The first depth is substantially equal to the second depth.
