Daystate Mk4 iS

The Daystate Mk 4 takes the revolutionary electronic system to the next level. Featuring a new version of the Harper Patent electronic firing system called MCT (Mapped Compensated Technology) which uses pressure feedback from the air cylinder to "regulate" power. The Mk4 also features the new Harper "sling-shot" valve. These new systems increase shot count and consistency greatly over previous versions. The increase in efficiency also makes it more quiet to shoot. The Mk4 S has a Sporter walnut stock with modern lines, while the ST has a Sporter-Thumbhole walnut stock with similar lines.

The CDT electronic firing system comes complete with features such as shot counter, magazine counter, and single-shot mode. The Daystate Mk4 comes with all of the fancy features disabled, but they are easily activated as needed.
