RA-Tech NPAS Kit for WE Open Bolt Rifles
RA-Tech NPAS Kit for WE Open Bolt Rifles. The simple fact is that a great many WE Open Bolt rifles come from the factory shooting too "hot" for UK site limits, so if you turn up on site with a standard GBB rifle and depending on various factors, you can be shooting over the site FPS and Joule limits. With this NPAS kit installed, you can fine tune your FPS to be within legal limits even if you decide to use more powerful gasses. Also helps to prevent the Joule Creep phenomenon associated with using heavier BBs in Gas Blow Back rifles.
