Some of the features include:

+  Excellent power upgrade.

+  Easy to adjust for a flatter shooting and more powerful shot string, for lots of accurate shots per fill.

+  Valve body and valve cap are precision CNC machined from a solid piece of 7075 aluminum, then are anodized blue to prevent corrosion.

+  The valve body and end cap both have a large internal volume, for more air capacity. 

+  Works with the factory or hill transfer ports and hammer springs.

+  Flows more air than a factory valve, for more power with lower or higher – comparable fill pressures

+  Can be used in an otherwise stock airgun, or can be used to help create the ideal tune in your customized airgun project. 

+  Durable – built to last forever.

+  No missed shots:  No internal o-rings that can hang up, break, or create negative issues and no expensive parts to have to replace.

+  Best choice for regulated or unregulated applications.
