Blowforward Mechanics
Overview
Blowforward mechanics describe systems where stored gas drives a bolt or internal assembly forward to chamber and fire a paintball, often using returning springs or opposing air chambers for reset.
Key Points
- Gas pressure is applied to move the bolt or internal shuttle toward the breech.
- Forward motion both chambers the paintball and initiates gas release.
- Return forces are provided by springs or differential pressure arrangements.
- Designs emphasize directed forward motion rather than rearward blowback.
- Blowforward behavior appears in multiple mechanical and pneumatic architectures.
Details
In blowforward based systems, compressed gas is used to push a bolt or shuttle forward instead of relying on rearward reaction forces for cycling. When activation occurs, a controlled volume of gas acts on a surface area of the bolt assembly, driving it toward the breech. As the bolt reaches its forward position, ports or openings align to allow gas into the firing chamber, accelerating the paintball.
Once the firing event is complete and pressure equalizes or vents, a spring or opposing air chamber returns the bolt assembly to its resting position. The sequence separates forward actuation from the reaction driven mechanisms seen in traditional blowback platforms. This approach can provide more direct control over how gas pressure is applied to the bolt during the chambering and sealing stages.
Blowforward concepts appear in several marker families and can be combined with various valve types. The characteristic feature is that gas energy is used primarily to move the bolt forward as part of the firing process rather than to push the bolt rearward after firing.
